Error building with icx (intel clang-cl) #94

Closed lalishansh closed 1 year ago

lalishansh commented 2 years ago 
clang-cl: error: argument unused during compilation: '-Qspectre' [-Werror,-Wunused-command-line-argument]
clang-cl: error: argument unused during compilation: '-MP' [-Werror,-Wunused-command-line-argument]

when invoked from intel/llvm/sycl/buildbot/compile.py

(inorder to make it work, i removed /MP and /Qspectre flags which is a bad thing to do i guess) Platform: Windows 11, build 22000.778

I don't use Windows, but I assume /MP and/Qspectre options actually work with (latest?) MSVC, i.e. you should file this bug also against clang-cl (which is supposed to emulate MSVC options). Bug on level-zero CMakefile is not checking that these options work with the available MSVC version, before using them.
