| 6l is a modified version of the Plan 9 linker. The original is documented at |
| |
| http://plan9.bell-labs.com/magic/man2html/1/2l |
| |
| Its target architecture is the x86-64, referred to by these tools as amd64. |
| It reads files in .6 format generated by 6g, 6c, and 6a and emits |
| a binary called 6.out by default. |
| |
| Major changes include: |
| - support for ELF and Mach-O binary files |
| - support for segmented stacks (this feature is implemented here, not in the compilers). |
| |
| |
| Original options are listed in the link above. |
| |
| Options new in this version: |
| |
| -d |
| Elide the dynamic linking header. With this option, the binary |
| is statically linked and does not refer to dynld. Without this option |
| (the default), the binary's contents are identical but it is loaded with dynld. |
| -e |
| Emit an extra ELF-compatible symbol table useful with tools such as |
| nm, gdb, and oprofile. This option makes the binary file considerably larger. |
| -H6 |
| Write Apple Mach-O binaries (default when $GOOS is darwin) |
| -H7 |
| Write Linux ELF binaries (default when $GOOS is linux) |
| -L dir1,dir2,.. |
| Search for libraries (package files) in the comma-separated list of directories. |
| The default is the single location $GOROOT/pkg/$GOOS_amd64. |
