| 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 ##. | |
| For more information, see https://golang.org/doc/asm. | |
