Especially on other architechtures (like arm) that have seen some horrific
bugs creep into gcc to do with certain optimisations. There hasnt even been a
good pipeline optimisation scheme until very recently in gcc, so any piplined
architechture (read pretty much all) is even harder to work out wheter some
cpu specific optimisation is _good_. Do people even understand how difficult
it is to write an optimising compiler (and prove some optimisation actually
works) for a complex architecture like the P4 or a modern powerPC chip?
Im getting sick of these arguments too and have to agree with Andrew on this
one, this is getting old and boring and being argues by too many people who
simply dont understand how modern processors and compilers work.
