CMAKE might be the culprit if the generation of libLLVM.so file ( 3.7.0 version
) has problems,

I found two interesting links about the "CMAKE way" when building LLVM 3.7.0 :

https://llvm.org/bugs/show_bug.cgi?id=23649

http://lists.freedesktop.org/archives/mesa-dev/2015-September/095696.html

and I found also that archlinux developers for the 3.6.2 version of LLVM have
used the classic way ( ./configure, make, make install ) for building LLVM
3.6.2,

then for the 3.7.0 version they have switched ( archlinux developers ) to the
CMAKE build method,

LLVM 3.6.2 lib works without problems with mesa 11.0.3, LLVM 3.7.0 lib triggers
a crash when mesa 11.0.3 tries to use it ( when r600 driver is used with an amd
radeon HD4650 pcie card ),

it's just a supposition : my bug could be the consequence of the switch to the
CMAKE build method, something went wrong in CMAKE files configuration in LLVM
3.7.0,

to be sure I am currently trying to compile LLVM 3.7.0 with the classic way (
./configure ) by reverting this patch in order to allow this :

http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20150629/284970.html

and I will see if the bug is still here when libLLVM.so.3.7 is building with
./configure and not CMAKE
