I can sympathize with that, I have a slightly different problem.  Right
now there are some java test that time-out 10x on solaris2.10.  I run four
passes of the testsuite with different options each time, so that 40
timeouts.  (This is without any extra RTL checking turned on.)  At 5
minutes each it adds up fast!

Maybe in another six years cpu improvements will outpace gcc bootstrap
times enough to reconsider.

In the mean time, I would encourage anyone patching middle-end RTL files
and especially backend target files to try using RTL checking to validate
their patches if they have enough spare cpu and time.
