Evan Cheng ea1450742e Added option -enable-finite-only-fp-math. When on, the codegen can assume that 
FP arithmetic arguments and results are never NaNs or +=Infs. This includes
ignoring parity flag (PF) when checking for FP equality.

I'm suprised it didn't cause more!

Evan Cheng 401049ce33 - Use of load's chain result should be redirected to load's chain operand. 
If it reads the chain result of the call, then the use, callseq_start,
  and call would form a cycle!
- Don't forget handle node replacement!
- There could also be a TokenFactor between the load and the callseq_start.

Evan Cheng f838cfcfbe Handle indirect call which folds a load manually. This never matches by 
the TableGen generated code since the load's chain result is read by
the callseq_start node.

Evan Cheng feca91a516 These can be transformed into lea as well. Not that we use this feature 
currently...

Evan Cheng 7b8feb27c8 - Use exact-width integer types, e.g. int32_t, to avoid confusion. 
- Fix a couple of minor bugs in i16immSExt8 and i16immZExt8.
- Added loadiPTR fragment used for indirect jumps and calls.

Chris Lattner c0a65d5ac8 Use class tags instead of struct tags. The coding standards specify this 
for public classes for improved win32 compatibility.

Evan Cheng 1c8ef9832f Explicitly specify MOV32mi can only be used store 32-bit GV, etc. 
llvm-svn: 28390
 2006-05-19 07:30:36 +00:00
Evan Cheng 886e8f35aa Now that iPTR is a fully resolved type. We end up losing the type check for 
patterns that look like this:

def : Pat<(i32 (X86Wrapper tconstpool  :$dst)), (MOV32ri tconstpool  :$dst)>;

InsertOneTypeCheck should copy the type from the resolved pattern to the
unresolved one as long as there types are different.

Evan Cheng f3cbd7ef31 Added a Flags field to TargetOperandInfo. Currently the only flag is 
M_LOOK_UP_PTR_REG_CLASS which allows the register class of the operand to be
resolved via a callback at runtime.
