Seems that even in IRA world we made no progress
j...@evans:/abuild/jh/trunk-3/build-inst2/gcc ./xgcc -B ./ -O3 reg.i
j...@evans:/abuild/jh/trunk-3/build-inst2/gcc tim e./a.out
If 'tim' is not a typo you can run the following command to lookup the package
that contains the binary:
command-not-found tim
bash: tim: command not found
j...@evans:/abuild/jh/trunk-3/build-inst2/gcc time ./a.out
 1000.8

real0m5.179s

sys 0m0.000s
j...@evans:/abuild/jh/trunk-3/build-inst2/gcc gcc-4.3  -O3 reg.i
j...@evans:/abuild/jh/trunk-3/build-inst2/gcc time ./a.out

-fno-tree-pre -fno-inline -fschedule-insns makes no difference

Adding vladimir to list as it is partly RA issue
