...ecific constraints, you'll want to look here: http://gcc.gnu.org/onlinedocs/gcc-4.7.0/gcc/Machine-Constraints.html I'll note that the "s" in the %s0 means to only print the low 5 bits of operand 0. I think that may only be documented in the src: gcc/config/rs6000/rs6000.c:print_operand() Peter

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
