History

Dale Curtis 50e30d9bb7 Don't use _tzcnt instrinics with clang for windows w/o BMI. ... Technically _tzcnt* intrinsics are only available when the BMI instruction set is present. However the instruction encoding degrades to "rep bsf" on older processors. Clang for Windows debatably restricts the _tzcnt* instrinics behind the __BMI__ architecture define, so check for its presence or exclude the usage of these intrinics when clang is present.
