src/external/gpl3/gcc/dist/gcc/config/i386: netbsd-elf.h
Log Message:
tell the compiler that the i387 runs in double-rounding mode, so it
doesn't need to issue memory store-read sequences to kill excess
precision. makes code smaller and faster, depending on optimization
flags
(as tests on Linux have shown, the compiler doesn't even succeed in
avoiding excess precision)
