I am actually pleasantly surprised by the failure of other major uP/system/compiler vendors
to bother duplicating Sun's stupid compiler trick on 179.art. The nature of the optimization
is apparently well understood. It seems to be just general enough not to run afoul of SPEC
rules governing customized optimization for SPEC source code. I would have loved being
a fly on the wall during the first submission review discussions though.
Everyone who is serious about HPC knows about the invisible asterix on Sun SPECfp2k
scores and takes it into account. Sun had better hope people don't get too used to discounting
UltraSPARC FP benchmark scores by 20% in the time it takes to bring out SPEC CPU 2005
(or whatever the successor to CPU2k is called) or it will have deservedly backfired on them.
