Mesa graphics stack fails to compile with Intel Parallel Studio XE 2017 for Linux / 64bit.

Hi,

I was trying to compile MESA (64bit) on Archlinux 64bit with Intel Parallel Studio XE 2017 for Linux / 64bit and hit a failure. ***I've attached a log from the build.

The ArchLinux distribution and many Linux distributions are enabling the DX3D9 support in MESA (DirectX 3d 9 'nine' driver via the --enable-nine flag), however, due to ICC not supporting x86_64-ms_abi / __builtin_ms_va_list which IS supported in GCC and LLVM, ICC will fail to build MESA. I've brought up this issue in the past, including recently in this post; https://software.intel.com/en-us/forums/intel-c-compiler/topic/691352 ...

Supporting __builtin_ms_va_list within the compiler is becoming more and more relevant, I really wish that the XE developers would seriously consider adding support for this, as it would be very useful and greatly appreciated...

The current solution is to either disable MESA's DX3D9/nine driver (via --disable-nine flag) or build mesa with GCC.

Thanks,

jordan
