Scott Michel a6729e8666 Give TargetLowering::getSetCCResultType() a parameter so that ISD::SETCC's 
return ValueType can depend its operands' ValueType.

This is a cosmetic change, no functionality impacted.

Evan Cheng 4a3c5eab34 - Fix a subtle bug in RemoveCopyByCommutingDef. ALR is the live range where the source is defined; BLR is the live range which is defined by the copy. 
If ALR and BLR overlaps and end of BLR extends beyond end of ALR, e.g.

Evan Cheng b5d11980d9 Avoid creating BUILD_VECTOR of all zero elements of "non-normalized" type (e.g. v8i16 on x86) after legalizer. Instruction selection does not expect to see them. In all likelihood this can only be an issue in a bugpoint reduced test case.

Christopher Lamb 4ba3f0430b Allow insert_subreg into implicit, target-specific values. 
Change insert/extract subreg instructions to be able to be used in TableGen patterns.
Use the above features to reimplement an x86-64 pseudo instruction as a pattern.

Chris Lattner 3e4683262e implement simple support for arbitrary token lookahead. Change the 
objc @try parser to use it, fixing a FIXME.  Update the 
objc-try-catch-1.m file to pass now that we get more reasonable 
errors.

Christopher Lamb 0faed2a9a6 Add support in TableGen for unknown operands that infer their type from the pattern their used in. This will be used to allow insert/extract subreg patterns in .td files!

 2008-03-10 04:13:41 +00:00
Ted Kremenek b73a43cc01 More cleanups with using the liveness analysis to removed dead symbols and 
variables from the symbolic state. Now we keep a mapping from the predecessor
node of a statement and its cleaned state, and interpose an accessor
"GetState()" to return the cleaned state when the node is the predecessor node,
and the real state otherwise. This obviates problem of ever accidentally
cleaning the state more than once (thus blowing away new bindings by mistake).

Dale Johannesen 4e622ec86d Increase ISD::ParamFlags to 64 bits. Increase the ByValSize 
field to 32 bits, thus enabling correct handling of ByVal
structs bigger than 0x1ffff.  Abstract interface a bit.
Fixes gcc.c-torture/execute/pr23135.c and 
gcc.c-torture/execute/pr28982b.c in gcc testsuite (were ICE'ing
on ppc32, quietly producing wrong code on x86-32.)

Chris Lattner aed9406bb7 Darwin PPC64 indirect call target goes in X12, not R12. This fixes these

Chris Lattner 78e817d7fc cell really does support cross-regclass moves, because R3 is in lots of different regclasses, and the code is not consistent when it comes to value tracking.

Ted Kremenek 6c50479737 When processing the transfer function for a statement, evaluate 
RemoveDeadBindings early because (1) it will always be called and (2) we can
dispatch to a plug-in transfer function that can evaluate the effect of dead
symbols (not yet added).

Ted Kremenek 2d063bef8b Refactored guards for "GRExprEngine::RemoveDeadBindings" directly into the

transparent to its callers.

Chris Lattner ce5f841bb5 fp_round's produced by getCopyFromParts should always be exact, because 
they are produced by calls (which are known exact) and by cross block copies
which are known to be produced by extends.

This improves:

define double @test2() {
	%tmp85 = call double asm sideeffect "fld0", "={st(0)}"()
	ret double %tmp85
}

from:

_test2:
	subl	$20, %esp
	# InlineAsm Start
	fld0
	# InlineAsm End
	fstpl	8(%esp)
	movsd	8(%esp), %xmm0
	movsd	%xmm0, (%esp)
	fldl	(%esp)
	addl	$20, %esp
	#FP_REG_KILL
	ret

to:

_test2:
	# InlineAsm Start
	fld0
	# InlineAsm End
	#FP_REG_KILL
	ret

by avoiding a f64 <-> f80 trip

Chris Lattner 86829f0ff7 teach X86InstrInfo::copyRegToReg how to copy into ST(0) from 
an RFP register class.

Teach ScheduleDAG how to handle CopyToReg with different src/dst 
reg classes.

This allows us to compile trivial inline asms that expect stuff
on the top of x87-fp stack.

 2008-03-09 08:50:23 +00:00
Chris Lattner 9e07537e8c Add ScheduleDAG support for copytoreg where the src/dst register are 
in different register classes, e.g. copy of ST(0) to RFP*.  This gets
some really trivial inline asm working that plops things on the top of
stack (PR879)

llvm-svn: 48105
