Reid Spencer 2a499b0b6c Implement review feedback. Most of this has to do with removing unnecessary 
cast instructions. A few are bug fixes.

llvm-svn: 32544
 2006-12-13 17:19:09 +00:00
John Criswell 2bcf535e0f Remove DSA.

Reid Spencer 612683b0d7 For mul transforms, when checking for a cast from bool as either operand, 
make sure to also check that it is a zext from bool, not any other cast
operation type.

Reid Spencer 799b5bfc71 Fix and/or/xor (cast A), (cast B) --> cast (and/or/xor A, B) 
The cast patch introduced the possibility that the wrong cast opcode
could be used and that this transform could trigger on different kinds
of cast operations. This patch rectifies that.

llvm-svn: 32538
 2006-12-13 08:27:15 +00:00
Reid Spencer df1f19a8ef Change the interface to SCEVExpander::InsertCastOfTo to take a cast opcode 
so the decision of which opcode to use is pushed upward to the caller.
Adjust the callers to pass the expected opcode.

Evan Cheng 0076ca0da9 - When expanding a bit_convert whose src operand is also to be expanded and 
its expansion result type is equal to the result type of the bit_convert,
e.g. (i64 bit_convert (f64 op)) if FP is not legal
returns the result of the expanded source operand.
- Store f32 / f64 may be expanded to a single store i32/i64.
