I just checked in some optimizations in machmode.h and rtl.c.
GET_MODE_MASK now uses an array instead of computing the mask at
runtime. This makes a noticable difference in compiler code size,
especially when HOST_WIDE_INT=long long.
Nice.
Although those new warnings emitted now will be tough to get rid of
for the larger modes (> HOST_BITS_PER_WIDE_INT) without some clever
preprocessing directives.
