* Fix the encoding of the armv7m (MClass) for MSR APSR writes which was missingKevin Enderby2012-05-174-15/+82
| | | | | | | | | | the 0b10 mask encoding bits. Make MSR APSR writes without a _<bits> qualifier an alias for MSR APSR_nzcvq even though ARM as deprecated it use. Also add support for suffixes (_nzcvq, _g, _nzcvqg) for APSR versions. Some FIXMEs in the code for better error checking when versions shouldn't be used. rdar://11457025 llvm-svn: 157019

* misched: Added 3-level regpressure back-off.Andrew Trick2012-05-173-75/+288
| | | | | | | | | | | | | | | | | | Introduce the basic strategy for register pressure scheduling. 1) Respect target limits at all times. 2) Indentify critical register classes (pressure sets). Track pressure within the scheduled region. Avoid increasing scheduled pressure for critical registers. 3) Avoid exceeding the max pressure of the region prior to scheduling. Added logic for picking between the top and bottom ready Q's based on regpressure heuristics. Status: functional but needs to be asjusted to achieve good results. llvm-svn: 157006

* Never clear <undef> flags on already joined copies.Jakob Stoklund Olesen2012-05-171-4/+6
| | | | | | | | | | | | | | | | | | | | | RegisterCoalescer set <undef> flags on all operands of copy instructions that are scheduled to be removed. This is so they won't affect shrinkToUses() by introducing false register reads. Make sure those <undef> flags are never cleared, or shrinkToUses() could cause live intervals to end at instructions about to be deleted. This would be a lot simpler if RegisterCoalescer could just erase joined copies immediately instead of keeping all the to-be-deleted instructions around. This fixes PR12862. Unfortunately, bugpoint can't create a sane test case for this. Like many other coalescer problems, this failure depends of a very fragile series of events. <rdar://problem/11474428> llvm-svn: 157001

This is more trouble that it is worth; autoreleasing a value without holding on it is a valid use-case, we should not "punish" correct code for the minority of broken/fragile programs that depend on the behavior of -autorelease. rdar://9914061 llvm-svn: 156999

| | | | | | | | | | | | | | | on it. TestBackticksWithoutATarget.BackticksWithNoTargetTestCase was calling GetDummyTarget() when executing for x86_64. When performing session tearDown, it would get destroyed (and everything would be invalid (arch, etc). Then the test would run for i386. The dummy target wasn't being reinitialized and was invalid. lldb complained that 'current process state is unsuitable for expression parsing'. llvm-svn: 156994

* Use RegUnits to compute overlapping registers.Jakob Stoklund Olesen2012-05-163-83/+54
| | | | | | | | | | | TableGen already computes register units as the basic unit of interference. We can use that to compute the set of overlapping registers. This means that we can easily compute overlap sets for one register at a time. There is no benefit to computing all registers at once. llvm-svn: 156960

* This patch adds the register class for MIPS16 as well as the ability forAkira Hatanaka2012-05-165-11/+26
| | | | | | | | | | | | | | | llc to recognize MIPS16 as a MIPS ASE extension. -mips16 will mean the mips16 ASE for mips32 by default. As part of fixing of adding this we discovered some small changes that need to be made to MipsInstrInfo::storeRegToStackSLot and MipsInstrInfo::loadRegFromStackSlot. We were using some "==" equality tests where in fact we should have been using Mips::<regclas>.hasSubClassEQ instead, per suggestion of Jakob Stoklund Olesen. Patch by Reed Kotler. llvm-svn: 156958
