disassembled release build with -mstackrealign

Here is my release build with -mstackrealign that works:

http://haagch.frickel.club/files/lib32-llvm-libs-svn-256101-1-x86_64.pkg.tar.gz
http://haagch.frickel.club/files/lib32-llvm-svn-256101-1-x86_64.pkg.tar.gz

They are compiled with -march=native for my ivy bridge cpu, so maybe that has
some influence.

Disassembling the same function shows different offsets for movaps:

   0x0047a805 <+69>:    movaps %xmm0,-0x48(%ebp)

   0x0047a815 <+85>:    movaps %xmm0,-0x38(%ebp)

You can check with

gdb -q /usr/lib32/libLLVM-3.8svn.so -ex "disassemble
LLVMAddTargetDependentFunctionAttr"

Probably:
movaps %xmm0,-0x48(%ebp) is right
movaps %xmm0,-0x40(%ebp) is wrong
