[LLVMdev] Odd PPC inline asm constraint
Hello,
I am not sure whether this is a clang issue, an LLVM issue, or both;
but clang chokes when parsing expanded macros from the
glibc /usr/include/bits/fenvinline.h with an error like:
./boost/math/tools/config.hpp:279:10: error: invalid input constraint
'i#*X' in asm feclearexcept(FE_ALL_EXCEPT);
^
/usr/include/bits/fenvinline.h:56:11: note: expanded from macro
'feclearexcept' : : "i#*X"(__builtin_ffs (__excepts)));...
