Andrew Lenharth 93341a0f82 WOW, function calls still seem to work after this.

Andrew Lenharth 8eb82fb524 added all flavors of zap for anding

 2005-04-13 03:47:03 +00:00
Chris Lattner 857624f47a Remove support for ZERO_EXTEND_INREG. This pessimizes code, genering stuff 
like this:

        ldah $1,1($31)
        lda $1,-1($1)
        and $0,$1,$24

instead of this:

        zap $0,252,$24

To get this back, the selector should recognize the ISD::AND case where this
happens and emit the appropriate ZAP instruction.

Andrew Lenharth 6b492bec30 fixup magic constant making code. tested by thousands of random divisions.... by 10000. ok, so random divisors would be good too, but this at least fixes some things

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)

Andrew Lenharth aa254d5f79 sure, I can set a flag, but if I never check it, why bother setting it? Should fix 20 programs :) 
llvm-svn: 20623
 2005-03-15 19:51:19 +00:00
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!
