Okay, I can see that. I was just wondering why for the bit-twiddling
builtins only 64 and 128 bit versions are generated on 64-bit
platforms while it's only possible to get 32 and 64 bit versions from
C (AFAIK, int, long, and long long can only have those widths in gcc).
Wouldn't it make more sense to hardcode 32 and 64 bit functions in
libgcc.c and then determine the correct mode code in libgcc.h?
