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
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.
-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
dump instructions as they are parsed
support references to Go symbols defined in other shared libraries
-o string
output file; default foo.o for /a/b/c/foo.s
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 ##.
