Evan Cheng 54c13da29c Added preliminary x86 subtarget support. 
llvm-svn: 25645
 2006-01-26 09:53:06 +00:00
Duraid Madina 0ebb0b1c5c fix stack corruption! Previously, 16-byte whole-FP-register stores were 
being treated as needing only 8 bytes (though they were 16 byte aligned.)

This should fix a bunch of tests - anyone have any comments, though?

  - in Target.td , SpillSize and SpillAlignment seem dead - is this what
    Size and Alignment do now?
  - in CodeGenRegisters.h/CodeGenTarget.cpp , DeclaredSpillSize and
    DeclaredSpillAlignment seem dead.
  - there are a bunch of comments here and there that don't clearly
    distinguish between 'size' and 'spillsize' etc. hmm.

Evan Cheng fcdce6d26f Work around some x86 Darwin assembler bugs 
llvm-svn: 25638
 2006-01-26 02:27:43 +00:00
Evan Cheng 944d1e91ea When trying to fold X86::SETCC into a Select, make a copy if it has more than 
one use. This allows more CMOV instructions.

llvm-svn: 25634
 2006-01-26 02:13:10 +00:00
Evan Cheng 97c68f0f5c Remove the uses of STATUS flag register. Rely on node property SDNPInFlag, 
SDNPOutFlag, and SDNPOptInFlag instead.

Nate Begeman e74795cd70 First part of bug 680: 
Remove TLI.LowerVA* and replace it with SDNodes that are lowered the same
way as everything else.

 2006-01-25 02:23:38 +00:00
Andrew Lenharth 94150f0666 maintaining stackpointer alignment. Perhaps it doesn't matter 
llvm-svn: 25592
 2006-01-25 01:51:08 +00:00
Chris Lattner 27d30a5f42 use ESP directly, not a copy of ESP into some other register for fastcc calls 
llvm-svn: 25584
 2006-01-24 06:14:44 +00:00
Chris Lattner 6f33eaeb81 Emit the copies out of call return registers *after* the ISD::CALLSEQ_END 
node, fixing fastcc and the case where a function has a frame pointer due
to dynamic allocas.

Duraid Madina 37c8ad14f4 die, die!! r15, you are not callee-saved 
llvm-svn: 25527
 2006-01-23 06:11:45 +00:00
Duraid Madina cc87402925 fix register corruption! (my god.) r15 is a scratch reg, using that as 
a frame pointer is a pretty doofus thing to do. use r5 instead, and
mark it callee-saved, coz that's what it is!

 2006-01-21 14:27:19 +00:00
Evan Cheng 468fecdc99 Rename fcmovae to fcmovnb and fcmova to fcmovnbe (following Intel manual). 
Some assemblers can't recognize the aliases.

 2006-01-21 02:55:41 +00:00
Chris Lattner 9436aa74a9 trivial formatting improvement: don't insert extra blank lines between .comm 
vars.

 2006-01-21 01:35:26 +00:00
Robert Bocchino 4b41c8e929 Make the C writer work with packed types. printContainedStructs is 
still not quite right and will be fixed later.
