Dale Johannesen 0de94a1712 Mark functions in some tests as 'nounwind'. Generating 
EH info for these functions causes the tests to fail for
random reasons (e.g. looking for 'or' or counting lines
with asm-printer; labels count as lines.)

Dale Johannesen ad6c23d5e9 Use ## for comment delimiter on darwin x86-32, so 
llvm's output .s files will go through gcc -std=c99
without triggering preprocesser errors.  Approach
suggested by Daveed Vandevoorde.

Evan Cheng df1690dc7c Handle a special case xor undef, undef -> 0. Technically this should be transformed to undef. But this is such a common idiom (misuse) we are going to handle it.

Dan Gohman 883cbfd0ba Add CMP32mr and friends to the load-unfolding table. Among 
other things, this allows the scheduler to unfold a load operand
in the 2008-01-08-SchedulerCrash.ll testcase, so it now successfully
clones the comparison to avoid a pushf+popf.

Evan Cheng 7d564c3b4a lastRegisterUse() should ignore identity copies. Those will be erased.

mask.

Evan Cheng 615488ab45 - SSE4.1 extractfps extracts a f32 into a gr32 register. Very useful! Not. Fix the instruction specification and teaches lowering code to use it only when the only use is a store instruction.

Chris Lattner c2c0c8303c apparently tclsh doesn't lex like bash. Weird.

Chris Lattner 9ca6bb4f16 pass the option so this test tests the right thing.

Evan Cheng c3cf9f872a Transform (zext (or (icmp), (icmp))) to (or (zext (cimp), (zext icmp))) if at least one of the (zext icmp) can be transformed to eliminate an icmp.

 2008-03-22 08:17:17 +00:00
Chris Lattner 53ccb62712 implement an initial hack at a straight-line store -> memset optimization. 
This fires dozens of times across spec and multisource, but I don't know
if it actually speeds stuff up.  Hopefully the testers will show something
nice :)

Chris Lattner 5abbe6cef5 Add support for calls that return two FP values in 
ST(0)/ST(1).

llvm-svn: 48634

Chris Lattner 7e59a30e9f disable a bogus assertion. 
llvm-svn: 48633
 2008-03-21 06:01:05 +00:00
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.

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.
