/*
|
|
Asm, typically invoked as ``go tool asm'', assembles the source file into an object
|
|
file named for the basename of the argument source file with a .o suffix. The
|
|
object file can then be combined with other objects into a package archive.
|
|
|
|
Command Line
|
|
|
|
Usage:
|
|
|
|
go tool asm [flags] file
|
|
|
|
The specified file must be a Go assembly file.
|
|
The same assembler is used for all target operating systems and architectures.
|
|
The GOOS and GOARCH environment variables set the desired target.
|
|
|
|
Flags:
|
|
|
|
-D value
|
|
predefined symbol with optional simple value -D=identifier=value;
|
|
can be set multiple times
|
|
-I value
|
|
include directory; can be set multiple times
|
|
-S print assembly and machine code
|
|
-debug
|
|
dump instructions as they are parsed
|
|
-dynlink
|
|
support references to Go symbols defined in other shared libraries
|
|
-o string
|
|
output file; default foo.o for /a/b/c/foo.s
|
|
-shared
|
|
generate code that can be linked into a shared library
|
|
-trimpath string
|
|
remove prefix from recorded source file paths
|
|
|
|
Input language:
|
|
|
|
The assembler uses mostly the same syntax for all architectures,
|
|
the main variation having to do with addressing modes. Input is
|
|
run through a simplified C preprocessor that implements #include,
|
|
#define, #ifdef/endif, but not #if or ##.
