Using crafty (a chess program) v14.13 with the assembler routines
disabled and running the internal bench mark (higher numbers are
better) on a 233 MHz Pentium II running FreeBSD-current results in:
egcs-19980608 : 1.01
egcs-19980621 with regmove.c & local-alloc.c from 1998-06-08 : 1.01
cvs 1998-06-28 : 0.95
cvs 1998-06-28 with regmove.c from 1998-06-08 : 0.99
It appears that the regmove regression is still present and that there
is possibly another new regression.
