The GCC testsuite results look OK. However, CSiBE shows
sum: 3342539 -> 3351695 +9156 / +0.273924 %
which is not so nice. For example, in bzip2/blocksort, the increase seems to
be caused mainly by things like:
before after
mov #92,r0 mov r15,r0
sub r7,r6 add #64,r0
mov.l @(r0,r15),r5 sub r7,r6
mov.l @(28,r0),r5
