Reid Spencer f47c779690 bug 122: 
remove redundant isa<GlobalValue>
ensure isa<GlobalValue> case is processed before is<Constant>

llvm-svn: 14926
 2004-07-17 23:36:58 +00:00
Reid Spencer 6dd4c27c7c bug 122: 
- Add ValueListTy to TypeTy so that the bcreader can have its own User
  category that won't get factored into any optimizations or cleanup.
- Correct an isa_impl to correctly include GlobalValue now that it isa
  Constant.

Reid Spencer 82b7ce69e1 bug 122: 
Now that GlobalVariable is a constant (via derivation from GlobalValue),
override the replaceUsesOfWithOnConstant method.

Reid Spencer 1a76c27988 bug 122:

Reid Spencer 88cda9db1e Extend constructor so that it can support GlobalValue's (with names). 
Make GlobalValue a "classof" Constant
Fix the classof(Value*) to include GlobalValue's

Chris Lattner e62af95bef It looks like physref->virtreg joining is working fine. Enable it by default 
but make virtreg->virtreg joining stay off by default

Chris Lattner c856e90d1d Make sure to emit the immediate byte for instructions like: 
shrd [mem], reg, imm

This fixes the jit-ls failure on 186.crafty.

Misha Brukman b85c2522fa * Use LI(S) to copy constants into registers intead of ADDI(S) as the latter is 
a funky way to "use" R0 for a 0-valued operand
* Add IMPLICIT_DEFs for incoming function arguments via registers to help the
  register allocator not clobber those registers
* Implement comparisons with longs
* Teach emitSelectOperation() to fold the SetCC operation
