[dev.regabi] cmd/compile: add Linksym helpers
Syms are meant to be just interned (pkg, name) tuples, and are a purely abstract, Go-language concept. As such, associating them with linker symbols (a low-level, implementation-oriented detail) is inappropriate. There's still work to be done before linker symbols can be directly attached to their appropriate, higher-level objects instead. But in the mean-time, we can at least add helper functions and discourage folks from using Sym.Linksym directly. The next CL will mechanically rewrite code to use these helpers where possible. Passes toolstash -cmp.

[dev.regabi] cmd/compile: move type size calculations into package types [generated]
To break up package gc, we need to put these calculations somewhere
lower in the import graph, either an existing or new package. Package types
already needs this code and is using hacks to get it without an import cycle.
We can remove the hacks and set up for the new package gc by moving the
code into package types itself.

[dev.regabi] cmd/compile: group known symbols, packages, names [generated]
There are a handful of pre-computed magic symbols known by
package gc, and we need a place to store them.
If we keep them together, the need for type *ir.Name means that
package ir is the lowest package in the import hierarchy that they
can go in. And package ir needs gopkg for methodSymSuffix
(in a later CL), so they can't go any higher either, at least not all together.
So package ir it is.
Rather than dump them all into the top-level package ir
namespace, however, we introduce global structs, Syms, Pkgs, and Names,
and make the known symbols, packages, and names fields of those.

[dev.regabi] cmd/compile: remove Left, Right etc methods [generated]
Now that the generic graph structure methods - Left, Right, and so on -
have been removed from the Node interface, each implementation's uses
can be replaced with direct field access, using more specific names,
and the methods themselves can be deleted.
Passes buildall w/ toolstash -cmp.

[dev.regabi] cmd/compile: collect global compilation state
There are various global variables tracking the state of the compilation. Collect them in a single global struct instead. The struct definition is in package ir, but the struct itself is still in package gc. It may eventually be threaded through the code, but in the short term will end up in package typecheck.

[dev.regabi] cmd/compile: remove uses of Name.Offset, Name.copy
For globals, Name.Offset is used as a way to address a field within a global during static initialization. This CL replaces that use with a separate NameOffsetExpr (ONAMEOFFSET) node. For locals, Name.Offset is the stack frame offset. This CL calls it that (FrameOffset, SetFrameOffset). Now there is no longer any use of Name.Offset or Name.SetOffset. And now that copies of Names are not being made to change their offsets, we can lock down use of ir.Copy on Names. The only remaining uses are during inlining and in handling generic system functions. At both those times you do want to create a new name and that can be made explicit by calling the new CloneName method instead. ir.Copy on a name now panics. Passes buildall w/ toolstash -cmp.

[dev.regabi] cmd/compile: cleanup for concrete types - sinit
An automated rewrite will add concrete type assertions after a test of n.Op(), when n can be safely type-asserted (meaning, n is not reassigned a different type, n is not reassigned and then used outside the scope of the type assertion, and so on). This sequence of CLs handles the code that the automated rewrite does not: adding specific types to function arguments, adjusting code not to call n.Left() etc when n may have multiple representations, and so on. This CL focuses on sinit.go. Passes buildall w/ toolstash -cmp.

[dev.regabi] cmd/compile: move Type, Sym printing to package types [generated]
Move the printing of types.Type and types.Sym out of ir into package types, where it properly belongs. This wasn't done originally (when the code was in gc) because the Type and Sym printing was a bit tangled up with the Node printing. But now they are untangled and can move into the correct package. This CL is automatically generated. A followup CL will clean up a little bit more by hand. Passes buildall w/ toolstash -cmp.

[dev.regabi] cmd/compile: refactoring prep for ConstExpr
The next CL adds ConstExpr, which is a more memory efficient
representation for constant expressions than Name. However, currently
a bunch of Val helper methods are defined on Name. This CL changes
them into standalone functions that work with any Node.Val
implementation.
There's also an existing standalone function named Int64Val, which
takes a Type argument to specify what type of integer is expected. So
to avoid collisions, this CL renames it to IntVal.
Passes buildall w/ toolstash -cmp.

[dev.regabi] cmd/compile: clean up Name and Func uses
Now that we have specific types for ONAME and ODCLFUNC nodes (*Name and *Func), use them throughout the compiler to be more precise about what data is being operated on. This is a somewhat large CL, but once you start applying the types in a few places, you end up needing to apply them to many other places to keep everything type-checking. A lot of code also melts away as types are added. Passes buildall w/ toolstash -cmp.

[dev.regabi] cmd/compile: replace *Node type with an interface Node [generated]
The plan is to introduce a Node interface that replaces the old *Node pointer-to-struct.
The previous CL defined an interface INode modeling a *Node.
This CL:
- Changes all references outside internal/ir to use INode,
along with many references inside internal/ir as well.
- Renames Node to node.
- Renames INode to Node
So now ir.Node is an interface implemented by *ir.node, which is otherwise inaccessible,
and the code outside package ir is now (clearly) using only the interface.
The usual rule is never to redefine an existing name with a new meaning,
so that old code that hasn't been updated gets a "unknown name" error
instead of more mysterious errors or silent misbehavior. That rule would
caution against replacing Node-the-struct with Node-the-interface,
as in this CL, because code that says *Node would now be using a pointer
to an interface. But this CL is being landed at the same time as another that
moves Node from gc to ir. So the net effect is to replace *gc.Node with ir.Node,
which does follow the rule: any lingering references to gc.Node will be told
it's gone, not silently start using pointers to interfaces. So the rule is followed
by the CL sequence, just not this specific CL.
Overall, the loss of inlining caused by using interfaces cuts the compiler speed
by about 6%, a not insignificant amount. However, as we convert the representation
to concrete structs that are not the giant Node over the next weeks, that speed
should come back as more of the compiler starts operating directly on concrete types
and the memory taken up by the graph of Nodes drops due to the more precise
structs. Honestly, I was expecting worse.

[dev.regabi] cmd/compile: convert types.Node (a pointer) to types.IRNode (an interface)
The pointer hack was nice and saved a word, but it's untenable in a world where nodes are themselves interfaces with different underlying types. Bite the bullet and use an interface to hold the Node when in types.Sym and types.Type. This has the nice benefit of removing AsTypesNode entirely. AsNode is still useful because of its nil handling.

the compiler IR it defines into a separate package that can be
imported by packages that gc itself imports. This CL does that.
It also removes the TINT8 etc aliases so that all code is clear
about which package things are coming from.
This CL is automatically generated by the script below.

[dev.regabi] cmd/compile: introduce cmd/compile/internal/base [generated]
Move Flag, Debug, Ctxt, Exit, and error messages to
new package cmd/compile/internal/base.
These are the core functionality that everything in gc uses
and which otherwise prevent splitting any other code
out of gc into different packages.
A minor milestone: the compiler source code
no longer contains the string "yy".

[dev.regabi] cmd/compile: clean up flag handling [generated]
The flag values have grown fairly haphazard, with no organization
or even common naming convention. This CL moves all flag values
into the Flag struct (formerly misnamed Debug), except for a few
that live in Ctxt fields instead.
This CL is entirely automated changes.
A followup CL will make a few manual cleanups, leaving this CL
completely automated and easier to regenerate during merge
conflicts.
Cleaning up flags is necessary because the printing routines
look at some of them, and the printing routines need to move
out of package gc to a new package shared by gc and any
other packages that split out of gc.

[dev.regabi] cmd/compile: replace Val with go/constant.Value
This replaces the compiler's legacy constant representation with go/constant, which is used by go/types. This should ease integrating with the new go/types-based type checker in the future.

This commit contains the compiler support for //go:embed lines. The go command passes to the compiler an "embed config" that maps literal patterns like *.txt to the set of files to embed. The compiler then lays out the content of those files as static data in the form of an embed.Files or string or []byte in the final object file. The test for this code is the end-to-end test hooking up the embed, cmd/compile, and cmd/go changes, in the next CL. For #41191.

cmd/compile: rename strlit, Bool, and Int64 *Node accessors
The Node type has shortcuts to access bool and int Values:
func (n *Node) Int64() int64
for n.Val().U.(*Mpint).Int64()
func (n *Node) Bool() bool
for n.Val().U.(bool)
I was convinced we didn't have one for string literal nodes, until I
noticed that we do, it's just called strlit, it's not a method, and
it's later in the file:
func strlit(n *Node) string
This change, for consistency:
- Renames strlit to StringVal and makes it a *Node method
- Renames Bool and Int64 to BoolVal and Int64Val
- Moves StringVal near the other two

cmd/compile: make funccompile non-reentrant
Currently, there's awkward reentrancy issue with funccompile:
funccompile -> compile -> dtypesym -> geneq/genhash/genwrapper -> funccompile
Though it's not a problem at this moment, some attempts by @mdempsky to
move order/walk/instrument into buildssa was failed, due to SSA cache
corruption.
This commit fixes that reentrancy issue, by making generated functions
to be pumped through the same compile workqueue that normal functions
are compiled. We do this by adding them to xtop, instead of calling
funccompile directly in geneq/genhash/genwrapper. In dumpdata, we look
for uncompiled functions in xtop instead of compilequeue, then finish
compiling them.
Updates #38463
Fixes #33485

[dev.link] cmd/internal/obj: handle content-addressable symbols with relocations
For content-addressable symbols with relocations, we build a content hash based on its content and relocations. Depending on the category of the referenced symbol, we choose different hash algorithms such that the hash is globally consistent. For now, we only support content-addressable symbols with relocations when the current package's import path is known, so that the symbol names are fully expanded. Otherwise, if the referenced symbol is a named symbol whose name is not fully expanded, the hash won't be globally consistent, and can cause erroneous collisions. This is fine for now, as the deduplication is just an optimization, not a requirement for correctness (until we get to type descriptors).

[dev.link] cmd/internal/goobj2, cmd/link: add content addressable symbols
This CL introduces content-addressable symbols (a.k.a. hashed symbols) to object files. Content-addressable symbols are identified and referenced by their content hashes, instead of by names. In the object file, a new pseudo-package index PkgIdxHashed is introduced, for content-addressable symbols, and a new block is added to store their hashes. The hashes are used by the linker to identify and deduplicate the symbols. For now, we only support content-addressable symbols that are always locally defined (i.e. no cross-package references). As a proof of concept, make string constant symbols content- addressable.

cmd/compile: delete gdata
All callers to gdata knew the kind of node they were working with, so all calls to gdata have been replaced with more specific calls. Some OADDR nodes were constructed solely for the purpose of passing them to gdata for unwrapping. In those cases, we can now cut to the chase. Passes toolstash-check.

cmd/compile: remove gdata layer in slicesym
The previous change moved code around to create slicesym. This change simplifies slicesym and its callsites by accepting an int64 for lencap instead of a node, and by removing all the calls to gdata. It also stops modifying n, which avoids the need to make a copy of it. Passes toolstash-check.

cmd/compile, cmd/link, runtime: make defers low-cost through inline code and extra funcdata
Generate inline code at defer time to save the args of defer calls to unique (autotmp) stack slots, and generate inline code at exit time to check which defer calls were made and make the associated function/method/interface calls. We remember that a particular defer statement was reached by storing in the deferBits variable (always stored on the stack). At exit time, we check the bits of the deferBits variable to determine which defer function calls to make (in reverse order). These low-cost defers are only used for functions where no defers appear in loops. In addition, we don't do these low-cost defers if there are too many defer statements or too many exits in a function (to limit code increase). When a function uses open-coded defers, we produce extra FUNCDATA_OpenCodedDeferInfo information that specifies the number of defers, and for each defer, the stack slots where the closure and associated args have been stored. The funcdata also includes the location of the deferBits variable. Therefore, for panics, we can use this funcdata to determine exactly which defers are active, and call the appropriate functions/methods/closures with the correct arguments for each active defer. In order to unwind the stack correctly after a recover(), we need to add an extra code segment to functions with open-coded defers that simply calls deferreturn() and returns. This segment is not reachable by the normal function, but is returned to by the runtime during recovery. We set the liveness information of this deferreturn() to be the same as the liveness at the first function call during the last defer exit code (so all return values and all stack slots needed by the defer calls will be live). I needed to increase the stackguard constant from 880 to 896, because of a small amount of new code in deferreturn(). The -N flag disables open-coded defers. '-d defer' prints out the kind of defer being used at each defer statement (heap-allocated, stack-allocated, or open-coded). Cost of defer statement [ go test -run NONE -bench BenchmarkDefer$ runtime ] With normal (stack-allocated) defers only: 35.4 ns/op With open-coded defers: 5.6 ns/op Cost of function call alone (remove defer keyword): 4.4 ns/op Text size increase (including funcdata) for go binary without/with open-coded defers: 0.09% The average size increase (including funcdata) for only the functions that use open-coded defers is 1.1%. The cost of a panic followed by a recover got noticeably slower, since panic processing now requires a scan of the stack for open-coded defer frames.
