------- Comment #2 from wilson at gcc dot gnu dot org 2010-04-26 21:40 ------- GCC-4.3 is still broken; my testcase just doesn't happen to fail there. I suspect this is broken all of the way back to gcc-2.95. This does point to where the problem was exposed though. It is the -msched-stop-bits-after-every-cycle patch, which emits stop bits when we hit hardware resource limits. I get accidentally correct code on mainline if I use -mno-sched-stop-bits-after-every-cycle. This patch was added in between gcc-4.3 and gcc-4.4.
