I seem to have found the ghc/gcc 2.95 problem. There was a bug in one of
the constraints on an inline-assembly fragment in the PrimOp for small
integer multiplication; patch below.
I've run some benchmarks, and gcc 2.95 does a *much* better job than 2.7.2.1
of compiling the garbage collector: it lops an average of something like 15%
off the GC time. wheyhey!
Haven't tried gcc 2.95 on a Sparc yet.
Cheers,
Simon
