Subject: embedding a directive within macro arguments has undefined behavior
Jonathan,
I also noticed we have the warnings...
/sw/src/fink.build/llvm37-3.7.0-100/llvm-3.7.0.src/projects/openmp/runtime/src/kmp_tasking.c:1061:2:
warning: embedding a directive within macro arguments has undefined behavior [-Wembedded-directive] #if OMP_41_ENABLED ^
/sw/src/fink.build/llvm37-3.7.0-100/llvm-3.7.0.src/projects/openmp/runtime/src/kmp_tasking.c:1063:2:
warning: embedding a directive within macro arguments has undefined behavior [-Wembedded-directive] #else ^
Shouldn't the macro call to KA_TRACE be duplicated and the preprocessor directives be moved outside of the macro call argument list instead?
Jack
