Chris Lattner 68b11e14bc remove Evan's "ugly hack" that sorta attempted to get 
x86-64 return conventions correct, but was never enabled.
We can now do the "right thing" with multiple return values.

llvm-svn: 48635
 2008-03-21 06:50:21 +00:00
Chris Lattner 5abbe6cef5 Add support for calls that return two FP values in 
ST(0)/ST(1).

Chris Lattner 7e59a30e9f disable a bogus assertion.

Chris Lattner b6f04a3e0a Enable support for returning two long-double values in ST(0)/ST(1). 
This allows us to compile fp-stack-2results.ll into:

_test:
	fldz
	fld1
	ret

which returns 1 in ST(0) and 0 in ST(1).  This is needed for x86-64
_Complex long double.

Chris Lattner c44160ce6e Teach masked value is zero about add and sub, and use MVIZ to 
simplify things like (X & 4) >> 1 == 2  --> (X & 4) == 4.

since it is obvious that the shift doesn't remove any bits.

Ted Kremenek b7151c7ca8 LiveVariables analysis now uses intersect for the merge of block-level expression liveness information. 
The rationale is that a block-level expression cannot be live in a parent block unless it is live in all of the successor blocks.

Scott Michel bbaf3edace Add more patterns to match in the integer comparison test harnesses. 
Fix bugs encountered, mostly due to range matching for immediates;
the CellSPU's 10-bit immediates are sign extended, covering a
larger range of unsigned values.
