Andrew Lenharth f029d795f0 Try several things. 1) drop /i from FP ops 2) factor out FP to Int moves and provide 21264 support for those 3) match not 4) match ornot andnot xornot

Andrew Lenharth 6294dee913 two things: 1)evilness reduction patch, reduces the number of instructions hiding in the small jump CC moving code. 2)implement div of small data types by FP DIV (also reduces evilness and should speed things up)

 2005-03-22 00:24:07 +00:00
Andrew Lenharth aa254d5f79 sure, I can set a flag, but if I never check it, why bother setting it? Should fix 20 programs :)

Chris Lattner 531f9e92d4 This mega patch converts us from using Function::a{iterator|begin|end} to 
using Function::arg_{iterator|begin|end}.  Likewise Module::g* -> Module::global_*.

This patch is contributed by Gabor Greif, thanks!

Andrew Lenharth e0b789fdf5 so, if you beat on it, you too can talk emacs into having a sane indenting policy... Also, optimize many function calls with pc-relative calls (partial prologue skipping for that case coming soon), try to fix the random jumps to strange places problem by pesimizing div et. al. register usage and fixing up GP before using, some calling convention tweaks, and make frame pointer unallocatable (not strickly necessary, but let's go for correctness first)
