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.
