Description Jason Schulz 2015-11-10 04:28:46 UTC 
The llvm ebuilds don't link to libLTO.so in the binutils plugins directory (/usr/${CHOST}/binutils-bin/lib/bfd-plugins).  This causes problems for ar and friends when building with lto.

Reproducible: Always

Steps to Reproduce:
emerge llvm
Actual Results:  
libLTO.so isn't linked in /usr/${CHOST}/binutils-bin/lib/bfd-plugins

Expected Results:  
libLTO.so is linked in /usr/${CHOST}/binutils-bin/lib/bfd-plugins

$ qlist llvm | grep binutils
/usr/x86_64-pc-linux-gnu/binutils-bin/lib/bfd-plugins/LLVMgold.so

This is supported in all versions 3.3-r3 onwards...
Comment 2 Jason Schulz 2015-12-28 05:17:48 UTC 
My apologies, LLVMgold does fully support LLVM bitcode for the gold linker (ar, nm, etc...).
