The 32-bit processors in my PowerPC Mac and in QEMU don't have fctid, a 64-bit instruction. I got the idea from mach/proto/fp/fif8.c to extract the exponent, clear some bits to get an integer, then subtract the integer from the original value to get the fraction.	2016-10-17 00:39:59 -04:00

Rewrite .fif8 to avoid powerpc64 fctid

This fixes the SIGILL (illegal instruction) in startrek when firing
phasers.  The 32-bit processors in my PowerPC Mac and in QEMU don't
have fctid, a 64-bit instruction.

I got the idea from mach/proto/fp/fif8.c to extract the exponent,
clear some bits to get an integer, then subtract the integer from
the original value to get the fraction.
