Andrew Lenharth aa254d5f79 sure, I can set a flag, but if I never check it, why bother setting it? Should fix 20 programs :)

 2005-02-12 21:10:58 +00:00
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)
