* Don't try to split weird critical edges that really aren't:Jakob Stoklund Olesen2010-11-021-2/+12
| | | | | | | | | | | | | | | BB#1: derived from LLVM BB %bb.nph28 Live Ins: %AL Predecessors according to CFG: BB#0 TEST8rr %reg16384<kill>, %reg16384, %EFLAGS<imp-def>; GR8:%reg16384 JNE_4 <BB#2>, %EFLAGS<imp-use,kill> JMP_4 <BB#2> Successors according to CFG: BB#2 BB#2 These double CFG edges only ever occur in bugpoint-generated code, so there is no need to attempt something clever. llvm-svn: 117992
* Attempt to provide correct encodings for a number of other vld1 variants, ↵Owen Anderson2010-11-021-45/+59
| | | | | | | | which we can't test since we can neither generate nor parse them at the moment. llvm-svn: 117988
* Add aesthetic break.Owen Anderson2010-11-021-1/+1
| | | | llvm-svn: 117986
* Add correct NEON encodings for the "multiple single elements" form of vld.Owen Anderson2010-11-025-18/+53

* MachineLICM should not claim to be preserving the CFG when it can split criticalJakob Stoklund Olesen2010-11-011-1/+0
| | | | | | edges on demand. llvm-svn: 117982
* Be more precise about verifying missing kill flags.Jakob Stoklund Olesen2010-11-011-2/+4
| | | | | | | It is legal for an instruction to have two operands using the same register, only one a kill. This is interpreted as a kill. llvm-svn: 117981
* When inserting copies during splitting, always use the parent register as theJakob Stoklund Olesen2010-11-012-19/+16
| | | | | | | | | | | | source, and let rewrite() clean it up. This way, kill flags on the inserted copies are fixed as well during rewrite(). We can't just assume that all the copies we insert are going to be kills since critical edges into loop headers sometimes require both source and dest to be live out of a block. llvm-svn: 117980
* Explicitly check for non-consant reference in an LDRi12 instruction. Add FIXMEJim Grosbach2010-11-011-1/+10

* Remove unused function.Jim Grosbach2010-11-011-13/+0
| | | | llvm-svn: 117977
* Add support for alignment operands on VLD1-lane instructions.Bob Wilson2010-11-012-25/+46
| | | | | | This is another part of the fix for Radar 8599955. llvm-svn: 117976
* Missed reverting this bit.Bill Wendling2010-11-011-1/+1

| | | | llvm-svn: 117967
* Add NEON VLD1-lane instructions. Partial fix for Radar 8599955.Bob Wilson2010-11-015-4/+93
| | | | llvm-svn: 117964
* Add kill flag verification.Jakob Stoklund Olesen2010-11-011-2/+13
| | | | | | | | At least X86FloatingPoint requires correct kill flags after register allocation, and targets using register scavenging benefit. Conservative kill flags are not enough. llvm-svn: 117960
* Update kill flags while rewriting instructions after splitting.Jakob Stoklund Olesen2010-11-011-0/+3
| | | | llvm-svn: 117959
* Move the machine operand MC encoding patterns to the parent classes.Bill Wendling2010-11-012-41/+36
| | | | llvm-svn: 117956
* When folding away a (shl (shr)) pair, we need to check that the bits that ↵Owen Anderson2010-11-011-1/+1
| | | | | | | | will BECOME the low bits are zero, not that the current low bits are zero. Fixes <rdar://problem/8606771>. llvm-svn: 117953

| | | | | | from X86AsmParser.cpp llvm-svn: 117952
* When we look at instructions to convert to setting the 's' flag, we need to lookBill Wendling2010-11-012-7/+9
| | | | | | | | | | | | | | | | | | | | | | | | at more than those which define CPSR. You can have this situation: (1) subs ... (2) sub r6, r5, r4 (3) movge ... (4) cmp r6, 0 (5) movge ... We cannot convert (2) to "subs" because (3) is using the CPSR set by (1). There's an analogous situation here: (1) sub r1, r2, r3 (2) sub r4, r5, r6 (3) cmp r4, ... (5) movge ... (6) cmp r1, ... (7) movge ... We cannot convert (1) to "subs" because of the intervening use of CPSR. llvm-svn: 117950
* Don't assign new registers created during a split to the same stack slot, butJakob Stoklund Olesen2010-11-013-16/+3

* Add basic LiveStacks verification.Jakob Stoklund Olesen2010-11-011-0/+20
| | | | | | | When an instruction refers to a spill slot with a LiveStacks entry, check that the spill slot is live at the instruction. llvm-svn: 117944
