[Mesa-dev] [PATCH 4/7] Travis: add binutils 2.26 for a few more LLVM 3.9 builds

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

Otherwise we error out at link stage as follows:

/usr/lib/llvm-3.9/lib/libLLVMAMDGPUCodeGen.a(R600OptimizeVectorRegisters.cpp.o):
unrecognized relocation (0x2a) in section
`.text._ZNK12_GLOBAL__N_119R600VectorRegMerger16getAnalysisUsageERN4llvm13AnalysisUsageE'
/usr/bin/ld: final link failed: Bad value

Suspecting that there are due to LLVM/Clang itself being built with the
newer version. Something like that seems to be mentioned below.
AKA packaging bug or we're using the wrong package ;-)

AFAICT it has nothing to do with linking against libclang.so

Jan any reason you opted to address only one of the LLVM 3.9 builds?
Should we bother with the rest, set it globally, other?
