[LLVMdev] Regression testing on MSYS2 host with mingw-w64

[Martell Malone]

Hi Yaron,

I know you sent me some emails before about regression testing on MSYS2
So you might have some idea about this

I am getting a regression error on check-llvm.
With the llvm/trunk/test/ExecutionEngine/Interpreter/intrinsics.ll

FAIL: LLVM :: ExecutionEngine/Interpreter/intrinsics.ll (7635 of 14266)

the same failure happens for trunc, round and copysign.

Commenting out these declarations and calls result in a successful
make-check.

Have you any idea on how to fix this

Many Thanks
