[Bug 1371636]

 

I tested it with LLVM 3.4.2 and the same set of gcc-4.9.2 (svn) and binutils (svn) used to open this bug report and all built fine. So for me it looks like that LLVM 3.5.0 came with something changed. Is it not a same name of some function, introduced in LLVM 3.5.0 and present in Mesa before?
It seems to not be LTO issue if Kai really not uses it and with LLVM 3.4.2 it builds with LTO for me.
I checked content of ld/emultempl/elf32.em in my git replica and patch you are reffering to is incorporated.

  refers to overlapping FDEs

Status in The ARB phylogenetic analysis suite:

Status in “binutils” package in Ubuntu:
  Confirmed

Bug description:
  Since today mesa fails to build on Ubuntu 14.10 (both i386 and amd64)
  while it still builds fine on Ubuntu 14.04. Nothing relevant changed
  in mesa since previous build in my PPA (indeed just some vc4 code only
  built on arm), the bug is reported by ld which I noticed just got
  updated with binutils package.
