You can try to compile with -fno-var-tracking-assignments. That helps indeed: on a 1.2 GHz UltraSPARC-T2, the sparcv9 fmt test takes real 20:14:33.53 user 20:14:09.94 sys 12.42 without -fno-var-tracking-assignments, but real 16:41.37 user 16:11.86 sys 4.08 with it. This is still too slow for the default testsuite timeout of 5 min, but at least a much more reasonable range. Rainer
