Overview

8l 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, referred to by these tools for historical reasons as 386. It reads files in .8 format generated by 8g, 8c, and 8a and emits a binary called 8.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.

-Hplan9

Write Plan 9 32-bit format binaries (default when $GOOS is plan9)

-Hdarwin

Write Apple Mach-O binaries (default when $GOOS is darwin)

-Hlinux

Write Linux ELF binaries (default when $GOOS is linux)

-Hfreebsd

Write FreeBSD ELF binaries (default when $GOOS is freebsd)

-Hwindows

Write Windows PE32 binaries (default when $GOOS is windows)

-I interpreter

Set the ELF dynamic linker to use.

-L dir1 -L dir2

Search for libraries (package files) in dir1, dir2, etc.
The default is the single location $GOROOT/pkg/$GOOS_386.

-r dir1:dir2:...

Set the dynamic linker search path when using ELF.

-V

Print the linker version.
