reports a compilation problem with the new PowerPC64 assembler code:
m4 -I../ -DOPERATION_mulredc1 test -f mulredc1.asm || echo './'
mulredc1.asm >mulredc1.s
/bin/sh ../libtool --mode=compile gcc-4.2 -m64 -c -o mulredc1.lo mulredc1.s
libtool: compile: gcc-4.2 -m64 -c mulredc1.s -o mulredc1.o
mulredc1.s:40:Invalid mnemonic 'tocbase,'
mulredc1.s:41:Unknown pseudo-op: .size
mulredc1.s:41:Rest of line ignored. 1st junk character valued 95 (_).
mulredc1.s:58:Unknown pseudo-op: .size
mulredc1.s:58:Rest of line ignored. 1st junk character valued 46 (.).
make[2]: *** [mulredc1.lo] Error 1
With --disable-asm, it compiles, but he reports a speed regression wrt. 6.3, possibly due to disabled asm code.
