Chris Lattner 2812e79c23 Fix an off-by-one error that Nate's eagle eyes caught 
llvm-svn: 25231
 2006-01-11 23:16:29 +00:00
Chris Lattner dc43a3f237 Use the auto-insert BuildMI constructor to avoid an explicit insert. No 
functionality change, just code cleanup.

Chris Lattner 3280da3cda If a function has a non-zero sized frame, use an add to adjust the stack 
pointer in the epilog, not a load.

llvm-svn: 25225
 2006-01-11 22:15:18 +00:00
Nate Begeman 1b8121b227 Add bswap, rotl, and rotr nodes 
Add dag combiner code to recognize rotl, rotr
Add ppc code to match rotl

Targets should add rotl/rotr patterns if they have them

Chris Lattner 602dfea79c Fix calls that need to store values in stack slots, to not copy the stack 
pointer.  This allows us to emit stuff like this:

        li r10, 0
        stw r10, 56(r1)
        or r3, r10, r10
        or r4, r10, r10
        or r5, r10, r10
        or r6, r10, r10
        or r7, r10, r10
        or r8, r10, r10
        or r9, r10, r10
        bl L_bar$stub

instead of this:

        or r2, r1, r1     ;; Extraneous copy.
        li r10, 0
        stw r10, 56(r2)
        or r3, r10, r10
        or r4, r10, r10
        or r5, r10, r10
        or r6, r10, r10
        or r7, r10, r10
        or r8, r10, r10
        or r9, r10, r10
        bl L_bar$stub

wowness.

Chris Lattner eaf94a8d2e tblgen does this now 
llvm-svn: 25220
 2006-01-11 19:53:22 +00:00
Chris Lattner b41e92b04c This is no longer needed

 2006-01-11 19:52:46 +00:00
Chris Lattner 66f63f72f3 Dead FP arguments still use an incoming FP reg. This fixes 
Regression/CodeGen/PowerPC/2006-01-11-darwin-fp-argument.ll, which was
distilled from a miscompilation in 252.eon.

llvm-svn: 25217
 2006-01-11 18:21:25 +00:00
Chris Lattner 41c7f4a9ce Use Evan's outflag stuff to implement V8cmpicc. This allows us to write a 
pattern for SUBCCrr, and makes it trivial to add support for SUBCCri, eliminating
an instruction in the common "setcc X, imm" case.

llvm-svn: 25210
 2006-01-11 07:15:43 +00:00
Chris Lattner 8e0bee11e3 Write this pattern in canonical form, allowing more patterns to match. 
This implements Regression/CodeGen/SparcV8/xnor.ll

Evan Cheng bc7a0f44bd * Add special entry code main() (to set x87 to 64-bit precision). 
* Allow a register node as SelectAddr() base.
* ExternalSymbol -> TargetExternalSymbol as direct function callee.
* Use X86::ESP register rather than CopyFromReg(X86::ESP) as stack ptr for
  call parmater passing.

Duraid Madina 014e8ee806 heh, 'sif it'd be a legalizer bug. 
llvm-svn: 25172
 2006-01-10 05:26:01 +00:00
Duraid Madina e977a93bd5 support functions that return bool (this "should" work but doesn't, 
*maybe* due to a legalizer bug.)

Chris Lattner 20c88dfd1b Fix a compile crash building MultiSource/Applications/d with the new front-end. 
The PPC backend was generating random shift counts in this case, due to an
uninitialized variable.
