Rafael Espindola 42de34f013 Remove the gcc= option. llvm-gcc uses only as= Look for as in the path. Doing it here instead of llvm-gcc because llvm-gcc has nothing as convenient as sys::Program::FindProgramByName. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73383 91177308-0d34-0410-b5e6-96231b3b80d8		2009-06-15 10:14:18 +00:00

README.txt

This directory contains a plugin that is designed to work with binutils
gold linker. At present time, this is not the default linker in
binutils, and the default build of gold does not support plugins.

Obtaining binutils:

  cvs -z 9 -d :pserver:anoncvs@sourceware.org:/cvs/src login
  {enter "anoncvs" as the password}
  cvs -z 9 -d :pserver:anoncvs@sourceware.org:/cvs/src co binutils

This will create a src/ directory. Make a build/ directory and from
there configure binutils with "../src/configure --enable-gold --enable-plugins".
Then build binutils with "make all-gold".

To build the LLVMgold plugin, configure LLVM with the option
--with-binutils-include=/path/to/binutils/src/include/ --enable-pic. To use the
plugin, run "ld-new --plugin /path/to/libLLVMgold.so".
Without PIC libLTO and libLLVMgold are not being built (because they would fail
link on x86-64 with a relocation error: PIC and non-PIC can't be combined).
As an alternative to passing --enable-pic, you can use 'make ENABLE_PIC=1' in
your entire LLVM build.
