Chris Lattner 9f06f911d1 the latest assembler that runs on powerpc 10.4 machines doesn't 
support aligned comm.  Detect when compiling for 10.4 and don't
emit an alignment for comm.  THis will hopefully fix PR8198.

Oscar Fuentes 0c7eca334a Avoid warnings about implicit conversions to `bool' in MSVC. This time 
for real.

Jakob Stoklund Olesen 10117c762a Avoid using VNInfo::getCopy as much as possible. I want to get rid of it. 
llvm-svn: 114794
 2010-09-25 18:10:38 +00:00
Lang Hames 564956867e Removed VNInfo::isDefAccurate(). Def "accuracy" can be checked by testing whether LiveIntervals::getInstructionFromIndex(def) returns NULL.

Owen Anderson 2c5df619c4 Revert r114703 and r114702, removing the isConditionalMove flag from instructions. After further 
reflection, this isn't going to achieve the purpose I intended it for.  Back to the drawing board!

llvm-svn: 114710
 2010-09-23 23:45:25 +00:00
Owen Anderson 6e0e8d7d64 Add an TargetInstrDesc bit to indicate that a given instruction is a conditional move. 
Not intended functionality change, as nothing uses this yet.

Lang Hames fd1bc42230 Moved the PBQP allocator class out of the header and back in to the cpp file to hide the gory details. 
Allocator instances can now be created by calling createPBQPRegisterAllocator.

Tidied up use of CoalescerPair as per Jakob's suggestions.

Made the new PBQPBuilder based construction process the default. The internal construction process
remains in-place and available via -pbqp-builder=false for now. It will be removed shortly if the new
process doesn't cause any regressions.

Jim Grosbach 85dcd3d0f4 Add support for ELF PLT references for ARM MC asm printing. Adding a 
new VariantKind to the MCSymbolExpr seems like overkill, but I'm not sure
there's a more straightforward way to get the printing difference captured.
(i.e., x86 uses @PLT, ARM uses (PLT)).

 2010-09-22 20:11:43 +00:00
Chris Lattner a9e57e0eff Rework passing parent pointers into complexpatterns, I forgot 
that complex patterns are matched after the entire pattern has
a structural match, therefore the NodeStack isn't in a useful
state when the actual call to the matcher happens.

llvm-svn: 114489
 2010-09-21 22:00:25 +00:00
Dan Gohman b0c0eaf579 Add some utility routines. 
llvm-svn: 114483
 2010-09-21 21:20:13 +00:00
Devang Patel c3e4b141a3 Add insertAfter. This should have accompanied previous check-in. 
llvm-svn: 114481
 2010-09-21 21:10:42 +00:00
Chris Lattner dd83548fea just like they can opt into getting the root of the pattern being 
matched, allow ComplexPatterns to opt into getting the parent node
of the operand being matched.

llvm-svn: 114472
 2010-09-21 20:37:12 +00:00
Chris Lattner 0e023ea02a fix a long standing wart: all the ComplexPattern's were being 
passed the root of the match, even though only a few patterns
actually needed this (one in X86, several in ARM [which should
be refactored anyway], and some in CellSPU that I don't feel 
like detangling).   Instead of requiring all ComplexPatterns to
take the dead root, have targets opt into getting the root by
putting SDNPWantRoot on the ComplexPattern.

Chris Lattner a4f199720d finish pushing MachinePointerInfo through selectiondags. At this point, 
I think I've audited all uses, so it should be dependable for address spaces,
and the pointer+offset info should also be accurate when there.

llvm-svn: 114464
 2010-09-21 18:58:22 +00:00
Chris Lattner 886250c8f0 convert a couple more places to use the new getStore() 
llvm-svn: 114463
 2010-09-21 18:51:21 +00:00
Chris Lattner 6963c1f789 eliminate an old SelectionDAG::getTruncStore method, propagating 
MachinePointerInfo around more.

llvm-svn: 114452
 2010-09-21 17:42:31 +00:00
Chris Lattner 5e39ffd02f eliminate last SelectionDAG::getLoad old entrypoint, on to stores. 
llvm-svn: 114450
 2010-09-21 17:28:52 +00:00
Chris Lattner ea952f05a5 fix the code that infers SV info to be correct when dealing 
with an indexed load/store that has an offset in the index.

llvm-svn: 114449
 2010-09-21 17:24:05 +00:00
Jakob Stoklund Olesen 1ccded77c0 Add LiveInterval::find and use it for most LiveRange searching operations 
instead of calling lower_bound or upper_bound directly.

This cleans up the search logic a bit because {lower,upper}_bound compare
LR->start by default, and it is usually simpler to search LR->end.

Funnelling all searches through one function also makes it possible to replace
the search algorithm with something faster than binary search.

llvm-svn: 114448
 2010-09-21 17:12:18 +00:00
Jakob Stoklund Olesen 04610c63cb Remove dead method. 
llvm-svn: 114447
 2010-09-21 17:12:15 +00:00
Chris Lattner 3d178ed4d4 propagate MachinePointerInfo through various uses of the old 
SelectionDAG::getExtLoad overload, and eliminate it.

llvm-svn: 114446
 2010-09-21 17:04:51 +00:00
Chris Lattner 1ffcf527c7 continue MachinePointerInfo'izing, eliminating use of one of the old 
getLoad overloads.

Lang Hames 0937fc4b7f Added an additional PBQP problem builder which adds coalescing costs (both between pairs of virtuals, and between virtuals and physicals). 
llvm-svn: 114429
 2010-09-21 13:19:36 +00:00
Gabor Greif adbbb93d3d Move the search for the appropriate AND instruction 
into OptimizeCompareInstr.
This necessitates the passing of CmpValue around,
so widen the virtual functions to accomodate.

No functionality changes.

Chris Lattner 50287ea65a add some accessors 
llvm-svn: 114409
 2010-09-21 06:43:24 +00:00
Chris Lattner 82fd06d3ce it's more elegant to put the "getConstantPool" and 
"getFixedStack" on the MachinePointerInfo class.  While
this isn't the problem I'm setting out to solve, it is the
right way to eliminate PseudoSourceValue, so lets go with it.

llvm-svn: 114406

Chris Lattner 8363087ba8 ugh, missed a file.

 2010-09-21 06:16:40 +00:00
Chris Lattner 2510de2bea reimplement memcpy/memmove/memset lowering to use MachinePointerInfo 
instead of srcvalue/offset pairs.  This corrects SV info for mem 
operations whose size is > 32-bits.

llvm-svn: 114401
 2010-09-21 05:40:29 +00:00
Chris Lattner de93bb065d add some helpful accessors. 
llvm-svn: 114400
 2010-09-21 05:39:30 +00:00
Chris Lattner bc419ba98f add overloads for SelectionDAG::getLoad, getStore, getTruncStore that take a 
MachinePointerInfo.  Among other virtues, this doesn't silently  truncate the
svoffset to 32-bits.

Chris Lattner d2d58ada70 simplify interface to SelectionDAG::getMemIntrinsicNode, making it take a MachinePointerInfo 
llvm-svn: 114397
 2010-09-21 04:57:15 +00:00
Chris Lattner 15d84c460a chagne interface to SelectionDAG::getAtomic to take a MachinePointerInfo, 
eliminating some weird "infer a frame address" logic which was dead.
