It also dies making slarfx.o. I found out that one of three optimization
options has to be turned off, then g77 -O6 -mcpu=ev56 -Wa,-mev56 is
successful:

-fno-rerun-cse-after-loop OR -fno-schedule-insns OR -fno-strenght-reduce

Any comments, which one hurts least? Also, any gurus willing to explain
what these options really do?

Also, incorporating the newer RISC-tuned zgemm and cgemm from M. Dayde
poses no problem, so I replaced the older ones with these.

cu,

Jo
