Clean all the mess around KMP_USE_FUTEX and kmp_lock.h

Authored by pawosm01 on Apr 27 2016, 2:59 PM.



KMP_USE_FUTEX preprocessor definition defined in kmp_lock.h is used
inconsequently throughout LLVM libomp code.

  • some .c files that use this define do not include kmp_lock.h file, in effect guarded part of code are never compiled
  • some places in code use architecture-depending preprocessor logic expressions which effectively disable use of Futex for AArch64 architecture, all these places should use '#if KMP_USE_FUTEX' instead to avoid any further confusions
  • some places use KMP_HAS_FUTEX which is nowhere defined, KMP_USE_FUTEX should be used instead
