Evan Cheng ef932b067d - Use MRegister::regsOverlap(). 
- Allow LiveVariables to track liveness of more registers.

llvm-svn: 34379
 2007-02-17 11:09:47 +00:00
Evan Cheng 0479014657 Added removeLiveIn and more livein iterators.

Evan Cheng 9865be6d40 Added getReservedRegs(). 
llvm-svn: 34376
 2007-02-17 11:06:00 +00:00
Evan Cheng 6457b9eff4 - Added regsOverlap() to test if two registers overlap. Or in case they are 
virtual registers, test if they the same.
- Added a virtual method to return target specific reserved registers, e.g. SP.

Chris Lattner 1f7d60262e Fix ixaddrs as well, allowing ppc64 to compile to: 
_test2:
        li r2, 0
        lis r3, 1
        std r2, 9024(r3)
        blr

instead of:

_test2:
        lis r2, 1
        li r3, 0
        ori r2, r2, 9024
        std r3, 0(r2)
        blr

This implements CodeGen/PowerPC/LargeAbsoluteAddr.ll:test2

Chris Lattner 4a9c0bb147 Compile test/CodeGen/PowerPC/LargeAbsoluteAddr.ll to: 
_test:
        lis r2, 743
        li r3, 0
        stw r3, 32751(r2)
        blr

instead of:

_test:
        li r2, 0
        stw r2, 32751(48693248)
        blr

Implement support for ppc64 as well, allowing it to produce better code.

both ppc32 and ppc64.

Reid Spencer e4ff249d26 Remove an unnecessary predicate. 
Patch by Scott Michel.

llvm-svn: 34354
 2007-02-16 22:42:40 +00:00
Reid Spencer 1d0721209d Review changes: 
1. Function style changes.
2. 80-col violations.
3. Better names for things.
4. Arrange constructors so they all take bit width first.
5. Add named signed and unsigned comparison functions and remove the
   corresponding operators.
6. Remove operator&& and operator|| but provide a getBoolValue function which
   converts to bool as comparison against 0. This allows the normal && and
   || operators to be used as if (X.getBoolValue() && Y.getBoolValue())

Note: this still doesn't function 100% yet. I'm working on the bugs now.

Chris Lattner cf835ff85a rewrite Value::takeName to take advantage of the new symtab stuff. This 
causes it to require no allocations and no symtab lookups in the common
case.  This speeds up instcombine 9.2% on 447.dealII.
