[dev.cc] cmd/internal/obj: convert liblink C to Go This CL adds the real cmd/internal/obj packages. Collectively they correspond to the liblink library. The conversion was done using rsc.io/c2go's run script at rsc.io/c2go repo version 706fac7. This is not the final conversion, just the first working draft. There will be more updates, but this works well enough to use with go tool objwriter and pass all.bash.

This CL points to the right files by replacing http://code.google.com/p/inferno-os/source/browse with https://bitbucket.org/inferno-os/inferno-os/src/default To implement the change I wrote and ran this script in the root: $ grep -Rn 'http://code.google.com/p/inferno-os/source/browse' * \ | cut -d":" -f1 | while read F;do perl -pi -e \ 's/http:\/\/code.google.com\/p\/inferno-os\/source\/browse/https:\/\/bitbucket.org\/inferno-os\/inferno-os\/src\/default/g' $F;done I excluded any cmd/vendor changes from the commit.

// Loop alignment constants:
// want to align loop entry to LoopAlign-byte boundary,

// We define a loop entry as the target of a backward jump.
//
// gcc uses MaxLoopPad = 10 for its 'generic x86-64' config,
// and it aligns all jump targets, not just backward jump targets.
//
// As of 6/1/2012, the effect of setting MaxLoopPad = 10 here

Clean up encoding of PINSRQ, CMPSD to use explicit third arg instead of jamming it into an unused slot of a different arg. Also fix bug in old6a, which declared the wrong grammar. The accepted (and encoded) arguments to CMPSD etc are mem,reg not reg,mem. Code that did try to use mem,reg before would be rejected by liblink, so only reg,reg ever worked, so existing code is not affected. After this change, code can use mem,reg successfully. The real bug here is that the encoding tables inverted the argument order, making the comparisons all backward from what they say on the page. It's too late to swap them, though: people have already written code that expects the inverted comparisons (like in package math, and likely externally). The best we can do is make the argument that should and can take a memory operand accept it. Bit-for-bit compatibility checked against tree without this CL.

cmd/internal/obj/x86: take over i386 duty, clean up PINSRQ, CMPSD Make cmd/internal/obj/x86 support 32-bit mode and use instead of cmd/internal/obj/i386. Delete cmd/internal/obj/i386. Clean up encoding of PINSRQ, CMPSD to use explicit third arg instead of jamming it into an unused slot of a different arg. Also fix bug in old6a, which declared the wrong grammar. The accepted (and encoded) arguments to CMPSD etc are mem,reg not reg,mem. Code that did try to use mem,reg before would be rejected by liblink, so only reg,reg ever worked, so existing code is not affected. After this change, code can use mem,reg successfully. The real bug here is that the encoding tables inverted the argument order, making the comparisons all backward from what they say on the page. It's too late to swap them, though: people have already written code that expects the inverted comparisons (like in package math, and likely externally). The best we can do is make the argument that should and can take a memory operand accept it. Bit-for-bit compatibility checked against tree without this CL.

cmd/internal/obj/x86: take over i386 duty, clean up PINSRQ, CMPSD Make cmd/internal/obj/x86 support 32-bit mode and use instead of cmd/internal/obj/i386. Delete cmd/internal/obj/i386. Clean up encoding of PINSRQ, CMPSD to use explicit third arg instead of jamming it into an unused slot of a different arg. Also fix bug in old6a, which declared the wrong grammar. The accepted (and encoded) arguments to CMPSD etc are mem,reg not reg,mem. Code that did try to use mem,reg before would be rejected by liblink, so only reg,reg ever worked, so existing code is not affected. After this change, code can use mem,reg successfully. The real bug here is that the encoding tables inverted the argument order, making the comparisons all backward from what they say on the page. It's too late to swap them, though: people have already written code that expects the inverted comparisons (like in package math, and likely externally). The best we can do is make the argument that should and can take a memory operand accept it. Bit-for-bit compatibility checked against tree without this CL.

[dev.cc] cmd/internal/obj: convert liblink C to Go This CL adds the real cmd/internal/obj packages. Collectively they correspond to the liblink library. The conversion was done using rsc.io/c2go's run script at rsc.io/c2go repo version 706fac7. This is not the final conversion, just the first working draft. There will be more updates, but this works well enough to use with go tool objwriter and pass all.bash.

[dev.cc] cmd/internal/obj: convert liblink C to Go This CL adds the real cmd/internal/obj packages. Collectively they correspond to the liblink library. The conversion was done using rsc.io/c2go's run script at rsc.io/c2go repo version 706fac7. This is not the final conversion, just the first working draft. There will be more updates, but this works well enough to use with go tool objwriter and pass all.bash.

The accepted (and encoded) arguments to CMPSD etc are mem,reg not reg,mem.

* ycover[Yi0*Ymax + Ys32] = 1;
* ycover[Yi1*Ymax + Ys32] = 1;
* ycover[Yi8*Ymax + Ys32] = 1;
*
* which means that Yi0, Yi1, and Yi8 all count as Ys32 (signed 32)
* if that's what an instruction can handle.
*
* In parallel with the scan through the ytable for the appropriate line, there
* is a z pointer that starts out pointing at the strange magic byte list in
* the Optab struct. With each step past a non-matching ytable line, z
* advances by the 4th entry in the line. When a matching line is found, that
* z pointer has the extra data to use in laying down the instruction bytes.
* The actual bytes laid down are a function of the 3rd entry in the line (that
* is, the Ztype) and the z bytes.
*
* For example, let's look at AADDL. The optab line says:
* { AADDL, yaddl, Px, 0x83,(00),0x05,0x81,(00),0x01,0x03 },
*
* and yaddl says
* uchar yaddl[] =
* {
* Yi8, Yml, Zibo_m, 2,
* Yi32, Yax, Zil_, 1,
* Yi32, Yml, Zilo_m, 2,
* Yrl, Yml, Zr_m, 1,
* Yml, Yrl, Zm_r, 1,
* 0
* };
*
* so there are 5 possible types of ADDL instruction that can be laid down, and
* possible states used to lay them down (Ztype and z pointer, assuming z
* points at {0x83,(00),0x05,0x81,(00),0x01,0x03}) are:
*
* Yi8, Yml -> Zibo_m, z (0x83, 00)
* Yi32, Yax -> Zil_, z+2 (0x05)
* Yi32, Yml -> Zilo_m, z+2+1 (0x81, 0x00)
* Yrl, Yml -> Zr_m, z+2+1+2 (0x01)
* Yml, Yrl -> Zm_r, z+2+1+2+1 (0x03)
*
* The Pconstant in the optab line controls the prefix bytes to emit. That's
* relatively straightforward as this program goes.
*
* The switch on t[2] in doasm implements the various Z cases. Zibo_m, for
* example, is an opcode byte (z[0]) then an asmando (which is some kind of
* encoded addressing mode for the Yml arg), and then a single immediate byte.
* Zilo_m is the same but a long (32-bit) immediate.

cmd/internal/obj: switch to one global Aconv Aconv is the pretty-printer for instruction opcodes like AMOVQ. There was one for each architecture. Make the space of A names have a different region for each architecture, much as we did for the registers, so a single global Aconv function can do the work. Each architecture registers its region as a slice of names at a given offset. The global names like CALL and JMP are now defined only once. The A values are used for indexing tables, so make it easy to do the indexing by making the offset maskable. Remove a bunch of now-duplicated architecture-specific code.

Instead consolidate the basic information into a single new package cmd/internal/sys. Also, introduce new sys.I386, sys.AMD64, etc. names for the constants '8', '6', etc. and replace most uses of the latter. The notable exceptions are a couple of error messages that still refer to the old char-based toolchain names and function reltype in cmd/link. Passes toolstash/buildall.

cmd/5g etc: mechanical cleanup Run rsc.io/grind rev a26569f on C->Go conversions. The new change in grind is the inlining of goto targets. If code says 'goto x' and the block starting at label x is unreachable except through that goto and the code can be moved to where the goto is without changing the meaning of its variable names, grind does that move. Simlarly, a goto to a plain return statement turns into that return statement (even if there are other paths to the return statement). Combined, these remove many long-distance gotos, which in turn makes it possible to reduce the scope of more variable declarations. (Because gotos can't jump across declarations, the gotos were keeping the declarations from moving.) Checked bit-for-bit compatibility with toolstash + buildall. Reduces compiler runtime in html/template by about 12%.

cmd/5g etc: mechanical cleanup Run rsc.io/grind rev a26569f on C->Go conversions. The new change in grind is the inlining of goto targets. If code says 'goto x' and the block starting at label x is unreachable except through that goto and the code can be moved to where the goto is without changing the meaning of its variable names, grind does that move. Simlarly, a goto to a plain return statement turns into that return statement (even if there are other paths to the return statement). Combined, these remove many long-distance gotos, which in turn makes it possible to reduce the scope of more variable declarations. (Because gotos can't jump across declarations, the gotos were keeping the declarations from moving.) Checked bit-for-bit compatibility with toolstash + buildall. Reduces compiler runtime in html/template by about 12%.

cmd/5g etc: mechanical cleanup Run rsc.io/grind rev a26569f on C->Go conversions. The new change in grind is the inlining of goto targets. If code says 'goto x' and the block starting at label x is unreachable except through that goto and the code can be moved to where the goto is without changing the meaning of its variable names, grind does that move. Simlarly, a goto to a plain return statement turns into that return statement (even if there are other paths to the return statement). Combined, these remove many long-distance gotos, which in turn makes it possible to reduce the scope of more variable declarations. (Because gotos can't jump across declarations, the gotos were keeping the declarations from moving.) Checked bit-for-bit compatibility with toolstash + buildall. Reduces compiler runtime in html/template by about 12%.

cmd/5g etc: mechanical cleanup Run rsc.io/grind rev a26569f on C->Go conversions. The new change in grind is the inlining of goto targets. If code says 'goto x' and the block starting at label x is unreachable except through that goto and the code can be moved to where the goto is without changing the meaning of its variable names, grind does that move. Simlarly, a goto to a plain return statement turns into that return statement (even if there are other paths to the return statement). Combined, these remove many long-distance gotos, which in turn makes it possible to reduce the scope of more variable declarations. (Because gotos can't jump across declarations, the gotos were keeping the declarations from moving.) Checked bit-for-bit compatibility with toolstash + buildall. Reduces compiler runtime in html/template by about 12%.

Now register numbers are large, so a couple of fields in Addr need to go from int8 to int16 because they sometimes hold register numbers. Clean up their uses, which meant regenerating the yacc grammars for the assemblers. There are changes in this CL triggered by earlier changes to yacc, which had not been run in this directory.

cmd/5g etc: mechanical cleanup Run rsc.io/grind rev a26569f on C->Go conversions. The new change in grind is the inlining of goto targets. If code says 'goto x' and the block starting at label x is unreachable except through that goto and the code can be moved to where the goto is without changing the meaning of its variable names, grind does that move. Simlarly, a goto to a plain return statement turns into that return statement (even if there are other paths to the return statement). Combined, these remove many long-distance gotos, which in turn makes it possible to reduce the scope of more variable declarations. (Because gotos can't jump across declarations, the gotos were keeping the declarations from moving.) Checked bit-for-bit compatibility with toolstash + buildall. Reduces compiler runtime in html/template by about 12%.

[dev.ssa] cmd/compile: disable xor clearing when flags must be preserved The x86 backend automatically rewrites MOV $0, AX to XOR AX, AX. That rewrite isn't ok when the flags register is live across the MOV. Keep track of which moves care about preserving flags, then disable this rewrite for them. On x86, Prog.Mark was being used to hold the length of the instruction. We already store that in Prog.Isize, so no need to store it in Prog.Mark also. This frees up Prog.Mark to hold a bitmask on x86 just like all the other architectures.

cmd/internal/obj/x86: take over i386 duty, clean up PINSRQ, CMPSD Make cmd/internal/obj/x86 support 32-bit mode and use instead of cmd/internal/obj/i386. Delete cmd/internal/obj/i386. Clean up encoding of PINSRQ, CMPSD to use explicit third arg instead of jamming it into an unused slot of a different arg. Also fix bug in old6a, which declared the wrong grammar. The accepted (and encoded) arguments to CMPSD etc are mem,reg not reg,mem. Code that did try to use mem,reg before would be rejected by liblink, so only reg,reg ever worked, so existing code is not affected. After this change, code can use mem,reg successfully. The real bug here is that the encoding tables inverted the argument order, making the comparisons all backward from what they say on the page. It's too late to swap them, though: people have already written code that expects the inverted comparisons (like in package math, and likely externally). The best we can do is make the argument that should and can take a memory operand accept it. Bit-for-bit compatibility checked against tree without this CL.

cmd/internal/obj: make Rconv a global function Clean up the obj API by making Rconv (register pretty printer) a top-level function. This means that Dconv (operand pretty printer) doesn't need an Rconv argument. To do this, we make the register numbers, which are arbitrary inside an operand (obj.Addr), disjoint sets for each architecture. Each architecture registers (ha) a piece of the space and then the global Rconv knows which architecture-specific printer to use. Clean up all the code that uses Dconv. Now register numbers are large, so a couple of fields in Addr need to go from int8 to int16 because they sometimes hold register numbers. Clean up their uses, which meant regenerating the yacc grammars for the assemblers. There are changes in this CL triggered by earlier changes to yacc, which had not been run in this directory. There is still cleanup to do in Addr, but we're getting closer to that being easy to do.

Clean up encoding of PINSRQ, CMPSD to use explicit third arg instead of jamming it into an unused slot of a different arg. Also fix bug in old6a, which declared the wrong grammar. The accepted (and encoded) arguments to CMPSD etc are mem,reg not reg,mem. Code that did try to use mem,reg before would be rejected by liblink, so only reg,reg ever worked, so existing code is not affected. After this change, code can use mem,reg successfully. The real bug here is that the encoding tables inverted the argument order, making the comparisons all backward from what they say on the page. It's too late to swap them, though: people have already written code that expects the inverted comparisons (like in package math, and likely externally). The best we can do is make the argument that should and can take a memory operand accept it. Bit-for-bit compatibility checked against tree without this CL.

[dev.ssa] cmd/compile: fix PIC for SSA-generated code Access to globals requires a 2-instruction sequence on PIC 386. MOVL foo(SB), AX is translated by the obj package into: CALL getPCofNextInstructionInTempRegister(SB) MOVL (&foo-&thisInstruction)(tmpReg), AX The call returns the PC of the next instruction in a register. The next instruction then offsets from that register to get the address required. The tricky part is the allocation of the temp register. The legacy compiler always used CX, and forbid the register allocator from allocating CX when in PIC mode. We can't easily do that in SSA because CX is actually a required register for shift instructions. (I think the old backend got away with this because the register allocator never uses CX, only codegen knows that shifts must use CX.) Instead, we allow the temp register to be anything. When the destination of the MOV (or LEA) is an integer register, we can use that register. Otherwise, we make sure to compile the operation using an LEA to reference the global. So MOVL AX, foo(SB) is never generated directly. Instead, SSA generates: LEAL foo(SB), DX MOVL AX, (DX) which is then rewritten by the obj package to: CALL getPcInDX(SB) LEAL (&foo-&thisInstruction)(DX), AX MOVL AX, (DX) So this CL modifies the obj package to use different thunks to materialize the pc into different registers. We use the registers that regalloc chose so that SSA can still allocate the full set of registers.

[dev.ssa] cmd/compile: fix PIC for SSA-generated code Access to globals requires a 2-instruction sequence on PIC 386. MOVL foo(SB), AX is translated by the obj package into: CALL getPCofNextInstructionInTempRegister(SB) MOVL (&foo-&thisInstruction)(tmpReg), AX The call returns the PC of the next instruction in a register. The next instruction then offsets from that register to get the address required. The tricky part is the allocation of the temp register. The legacy compiler always used CX, and forbid the register allocator from allocating CX when in PIC mode. We can't easily do that in SSA because CX is actually a required register for shift instructions. (I think the old backend got away with this because the register allocator never uses CX, only codegen knows that shifts must use CX.) Instead, we allow the temp register to be anything. When the destination of the MOV (or LEA) is an integer register, we can use that register. Otherwise, we make sure to compile the operation using an LEA to reference the global. So MOVL AX, foo(SB) is never generated directly. Instead, SSA generates: LEAL foo(SB), DX MOVL AX, (DX) which is then rewritten by the obj package to: CALL getPcInDX(SB) LEAL (&foo-&thisInstruction)(DX), AX MOVL AX, (DX) So this CL modifies the obj package to use different thunks to materialize the pc into different registers. We use the registers that regalloc chose so that SSA can still allocate the full set of registers.

cmd/internal/obj/x86: position independent access to global data on 386 when -shared This works by adding a call to __x86.get_pc_thunk.cx immediately before any instruction that accesses global data and then assembling the instruction to use the appropriate offset from CX instead of the absolute address. Some forms cannot be assembled that way and are rewritten to load the address into CX first. -buildmode=pie works now, but is not yet tested.

cmd/8l, cmd/internal/ld, cmd/internal/obj/x86: stop incorrectly using the term "inital exec" The long comment block in obj6.go:progedit talked about the two code sequences for accessing g as "local exec" and "initial exec", but really they are both forms of local exec. This stuff is confusing enough without using the wrong words for things, so rewrite it to talk about 2-instruction and 1-instruction sequences. Unfortunately the confusion has made it into code, with the R_TLS_IE relocation now doing double duty as meaning actual initial exec when externally linking and boring old local exec when linking internally (half of this is my fault). So this stops using R_TLS_IE in the local exec case. There is a chance this might break plan9 or windows, but I don't think so. Next step is working out what the heck is going on on ARM...

cmd/5g etc: mechanical cleanup Run rsc.io/grind rev a26569f on C->Go conversions. The new change in grind is the inlining of goto targets. If code says 'goto x' and the block starting at label x is unreachable except through that goto and the code can be moved to where the goto is without changing the meaning of its variable names, grind does that move. Simlarly, a goto to a plain return statement turns into that return statement (even if there are other paths to the return statement). Combined, these remove many long-distance gotos, which in turn makes it possible to reduce the scope of more variable declarations. (Because gotos can't jump across declarations, the gotos were keeping the declarations from moving.) Checked bit-for-bit compatibility with toolstash + buildall. Reduces compiler runtime in html/template by about 12%.

cmd/internal/obj: make Rconv a global function Clean up the obj API by making Rconv (register pretty printer) a top-level function. This means that Dconv (operand pretty printer) doesn't need an Rconv argument. To do this, we make the register numbers, which are arbitrary inside an operand (obj.Addr), disjoint sets for each architecture. Each architecture registers (ha) a piece of the space and then the global Rconv knows which architecture-specific printer to use. Clean up all the code that uses Dconv. Now register numbers are large, so a couple of fields in Addr need to go from int8 to int16 because they sometimes hold register numbers. Clean up their uses, which meant regenerating the yacc grammars for the assemblers. There are changes in this CL triggered by earlier changes to yacc, which had not been run in this directory. There is still cleanup to do in Addr, but we're getting closer to that being easy to do.

cmd/internal/obj/x86: take over i386 duty, clean up PINSRQ, CMPSD Make cmd/internal/obj/x86 support 32-bit mode and use instead of cmd/internal/obj/i386. Delete cmd/internal/obj/i386. Clean up encoding of PINSRQ, CMPSD to use explicit third arg instead of jamming it into an unused slot of a different arg. Also fix bug in old6a, which declared the wrong grammar. The accepted (and encoded) arguments to CMPSD etc are mem,reg not reg,mem. Code that did try to use mem,reg before would be rejected by liblink, so only reg,reg ever worked, so existing code is not affected. After this change, code can use mem,reg successfully. The real bug here is that the encoding tables inverted the argument order, making the comparisons all backward from what they say on the page. It's too late to swap them, though: people have already written code that expects the inverted comparisons (like in package math, and likely externally). The best we can do is make the argument that should and can take a memory operand accept it. Bit-for-bit compatibility checked against tree without this CL.

cmd/internal/obj/x86: take over i386 duty, clean up PINSRQ, CMPSD Make cmd/internal/obj/x86 support 32-bit mode and use instead of cmd/internal/obj/i386. Delete cmd/internal/obj/i386. Clean up encoding of PINSRQ, CMPSD to use explicit third arg instead of jamming it into an unused slot of a different arg. Also fix bug in old6a, which declared the wrong grammar. The accepted (and encoded) arguments to CMPSD etc are mem,reg not reg,mem. Code that did try to use mem,reg before would be rejected by liblink, so only reg,reg ever worked, so existing code is not affected. After this change, code can use mem,reg successfully. The real bug here is that the encoding tables inverted the argument order, making the comparisons all backward from what they say on the page. It's too late to swap them, though: people have already written code that expects the inverted comparisons (like in package math, and likely externally). The best we can do is make the argument that should and can take a memory operand accept it. Bit-for-bit compatibility checked against tree without this CL.

cmd/internal/obj: switch to one global Aconv Aconv is the pretty-printer for instruction opcodes like AMOVQ. There was one for each architecture. Make the space of A names have a different region for each architecture, much as we did for the registers, so a single global Aconv function can do the work. Each architecture registers its region as a slice of names at a given offset. The global names like CALL and JMP are now defined only once. The A values are used for indexing tables, so make it easy to do the indexing by making the offset maskable. Remove a bunch of now-duplicated architecture-specific code.

cmd/5g etc: mechanical cleanup Run rsc.io/grind rev a26569f on C->Go conversions. The new change in grind is the inlining of goto targets. If code says 'goto x' and the block starting at label x is unreachable except through that goto and the code can be moved to where the goto is without changing the meaning of its variable names, grind does that move. Simlarly, a goto to a plain return statement turns into that return statement (even if there are other paths to the return statement). Combined, these remove many long-distance gotos, which in turn makes it possible to reduce the scope of more variable declarations. (Because gotos can't jump across declarations, the gotos were keeping the declarations from moving.) Checked bit-for-bit compatibility with toolstash + buildall. Reduces compiler runtime in html/template by about 12%.

If code says 'goto x' and the block starting at label x is unreachable except through that goto and the code can be moved to where the goto is without changing the meaning of its variable names, grind does that move. Simlarly, a goto to a plain return statement turns into that return statement (even if there are other paths to the return statement). Combined, these remove many long-distance gotos, which in turn makes it possible to reduce the scope of more variable declarations.

[dev.cc] cmd/internal/obj: convert liblink C to Go This CL adds the real cmd/internal/obj packages. Collectively they correspond to the liblink library. The conversion was done using rsc.io/c2go's run script at rsc.io/c2go repo version 706fac7. This is not the final conversion, just the first working draft. There will be more updates, but this works well enough to use with go tool objwriter and pass all.bash.

cmd/5g etc: mechanical cleanup Run rsc.io/grind rev a26569f on C->Go conversions. The new change in grind is the inlining of goto targets. If code says 'goto x' and the block starting at label x is unreachable except through that goto and the code can be moved to where the goto is without changing the meaning of its variable names, grind does that move. Simlarly, a goto to a plain return statement turns into that return statement (even if there are other paths to the return statement). Combined, these remove many long-distance gotos, which in turn makes it possible to reduce the scope of more variable declarations. (Because gotos can't jump across declarations, the gotos were keeping the declarations from moving.) Checked bit-for-bit compatibility with toolstash + buildall.

If code says 'goto x' and the block starting at label x is unreachable except through that goto and the code can be moved to where the goto is without changing the meaning of its variable names, grind does that move. Simlarly, a goto to a plain return statement turns into that return statement (even if there are other paths to the return statement).

If code says 'goto x' and the block starting at label x is unreachable except through that goto and the code can be moved to where the goto is without changing the meaning of its variable names, grind does that move. Simlarly, a goto to a plain return statement turns into that return statement (even if there are other paths to the return statement).

[dev.cc] cmd/internal/obj: convert liblink C to Go This CL adds the real cmd/internal/obj packages. Collectively they correspond to the liblink library. The conversion was done using rsc.io/c2go's run script at rsc.io/c2go repo version 706fac7. This is not the final conversion, just the first working draft. There will be more updates, but this works well enough to use with go tool objwriter and pass all.bash.

[dev.ssa] cmd/compile: fix PIC for SSA-generated code Access to globals requires a 2-instruction sequence on PIC 386. MOVL foo(SB), AX is translated by the obj package into: CALL getPCofNextInstructionInTempRegister(SB) MOVL (&foo-&thisInstruction)(tmpReg), AX The call returns the PC of the next instruction in a register. The next instruction then offsets from that register to get the address required. The tricky part is the allocation of the temp register. The legacy compiler always used CX, and forbid the register allocator from allocating CX when in PIC mode. We can't easily do that in SSA because CX is actually a required register for shift instructions. (I think the old backend got away with this because the register allocator never uses CX, only codegen knows that shifts must use CX.) Instead, we allow the temp register to be anything. When the destination of the MOV (or LEA) is an integer register, we can use that register. Otherwise, we make sure to compile the operation using an LEA to reference the global. So MOVL AX, foo(SB) is never generated directly. Instead, SSA generates: LEAL foo(SB), DX MOVL AX, (DX) which is then rewritten by the obj package to: CALL getPcInDX(SB) LEAL (&foo-&thisInstruction)(DX), AX MOVL AX, (DX) So this CL modifies the obj package to use different thunks to materialize the pc into different registers. We use the registers that regalloc chose so that SSA can still allocate the full set of registers.

cmd/5g etc: mechanical cleanup Run rsc.io/grind rev a26569f on C->Go conversions. The new change in grind is the inlining of goto targets. If code says 'goto x' and the block starting at label x is unreachable except through that goto and the code can be moved to where the goto is without changing the meaning of its variable names, grind does that move. Simlarly, a goto to a plain return statement turns into that return statement (even if there are other paths to the return statement). Combined, these remove many long-distance gotos, which in turn makes it possible to reduce the scope of more variable declarations. (Because gotos can't jump across declarations, the gotos were keeping the declarations from moving.) Checked bit-for-bit compatibility with toolstash + buildall. Reduces compiler runtime in html/template by about 12%.

Clean up encoding of PINSRQ, CMPSD to use explicit third arg instead of jamming it into an unused slot of a different arg. Also fix bug in old6a, which declared the wrong grammar. The accepted (and encoded) arguments to CMPSD etc are mem,reg not reg,mem.

The accepted (and encoded) arguments to CMPSD etc are mem,reg not reg,mem. Code that did try to use mem,reg before would be rejected by liblink, so only reg,reg ever worked, so existing code is not affected. After this change, code can use mem,reg successfully. The real bug here is that the encoding tables inverted the argument order, making the comparisons all backward from what they say on the page. It's too late to swap them, though: people have already written code that expects the inverted comparisons (like in package math, and likely externally). The best we can do is make the argument that should and can take a memory operand accept it. Bit-for-bit compatibility checked against tree without this CL.

Clean up encoding of PINSRQ, CMPSD to use explicit third arg instead of jamming it into an unused slot of a different arg. Also fix bug in old6a, which declared the wrong grammar. The accepted (and encoded) arguments to CMPSD etc are mem,reg not reg,mem. Code that did try to use mem,reg before would be rejected by liblink, so only reg,reg ever worked, so existing code is not affected. After this change, code can use mem,reg successfully. The real bug here is that the encoding tables inverted the argument order, making the comparisons all backward from what they say on the page. It's too late to swap them, though: people have already written code that expects the inverted comparisons (like in package math, and likely externally). The best we can do is make the argument that should and can take a memory operand accept it. Bit-for-bit compatibility checked against tree without this CL.

cmd/5g etc: mechanical cleanup Run rsc.io/grind rev a26569f on C->Go conversions. The new change in grind is the inlining of goto targets. If code says 'goto x' and the block starting at label x is unreachable except through that goto and the code can be moved to where the goto is without changing the meaning of its variable names, grind does that move. Simlarly, a goto to a plain return statement turns into that return statement (even if there are other paths to the return statement). Combined, these remove many long-distance gotos, which in turn makes it possible to reduce the scope of more variable declarations. (Because gotos can't jump across declarations, the gotos were keeping the declarations from moving.) Checked bit-for-bit compatibility with toolstash + buildall. Reduces compiler runtime in html/template by about 12%.

cmd/5g etc: mechanical cleanup Run rsc.io/grind rev a26569f on C->Go conversions. The new change in grind is the inlining of goto targets. If code says 'goto x' and the block starting at label x is unreachable except through that goto and the code can be moved to where the goto is without changing the meaning of its variable names, grind does that move. Simlarly, a goto to a plain return statement turns into that return statement (even if there are other paths to the return statement). Combined, these remove many long-distance gotos, which in turn makes it possible to reduce the scope of more variable declarations. (Because gotos can't jump across declarations, the gotos were keeping the declarations from moving.) Checked bit-for-bit compatibility with toolstash + buildall. Reduces compiler runtime in html/template by about 12%.

cmd/internal/obj/x86: position independent access to global data on 386 when -shared This works by adding a call to __x86.get_pc_thunk.cx immediately before any instruction that accesses global data and then assembling the instruction to use the appropriate offset from CX instead of the absolute address. Some forms cannot be assembled that way and are rewritten to load the address into CX first. -buildmode=pie works now, but is not yet tested.

cmd/internal/obj/x86: take over i386 duty, clean up PINSRQ, CMPSD Make cmd/internal/obj/x86 support 32-bit mode and use instead of cmd/internal/obj/i386. Delete cmd/internal/obj/i386. Clean up encoding of PINSRQ, CMPSD to use explicit third arg instead of jamming it into an unused slot of a different arg. Also fix bug in old6a, which declared the wrong grammar. The accepted (and encoded) arguments to CMPSD etc are mem,reg not reg,mem. Code that did try to use mem,reg before would be rejected by liblink, so only reg,reg ever worked, so existing code is not affected. After this change, code can use mem,reg successfully. The real bug here is that the encoding tables inverted the argument order, making the comparisons all backward from what they say on the page. It's too late to swap them, though: people have already written code that expects the inverted comparisons (like in package math, and likely externally). The best we can do is make the argument that should and can take a memory operand accept it. Bit-for-bit compatibility checked against tree without this CL.
