2011-12-07Add MachineOperand IsInternalRead flag.Jakob Stoklund Olesen
This flag is used when bundling machine instructions. It indicates whether the operand reads a value defined inside or outside its bundle. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145997 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-06Use conservative size estimate for tBR_JTr.Jakob Stoklund Olesen
This pseudo-instruction contains a .align directive in its expansion, so the total size may vary by 2 bytes. It is too difficult to accurately keep track of this alignment directive, just use the worst-case size instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145971 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-06Remove alignment from deserted constant islands.Jakob Stoklund Olesen
ARMConstantIslandPass may sometimes leave empty constant islands behind (it really shouldn't). Remove the alignment from the empty islands so the size calculations are still correct. This should fix the many Thumb1 assembler errors in the nightly test suite. The reduced test case for this problem is way too big. That is to be expected for ARMConstantIslandPass bugs. <rdar://problem/10534709> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145970 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-06Simplify common predecessor finding.Benjamin Kramer
- Walking over pred_begin/pred_end is an expensive operation. - PHINodes contain a value for each predecessor anyway. - While it may look like we used to save a few iterations with the set, be aware that getIncomingValueForBlock does a linear search on the values of the phi node. - Another -5% on ARMDisassembler.cpp (Release build). This was the last entry in the profile that was obviously wasting time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145937 91177308-0d34-0410-b5e6-96231b3b80d8

both. Do the same for the 256-bit version. Use loops to reduce size of isVSHUFPYMask. Fix test cases that were incorrectly passing due to isCommutedSHUFPMask not checking for the vector being 128-bit.

2011-12-06LSR: prune undesirable formulae early.Andrew Trick
It's always good to prune early, but formulae that are unsatisfactory in their own right need to be removed before running any other pruning heuristics. We easily avoid generating such formulae, but we need them as an intermediate basis for forming other good formulae. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145906 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-06Align ARM constant pool islands via their basic block.Jakob Stoklund Olesen
Previously, all ARM::CONSTPOOL_ENTRY instructions had a hardwired alignment of 4 bytes emitted by ARMAsmPrinter. Now the same alignment is set on the basic block. This is in preparation of supporting ARM constant pool islands with different alignments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145890 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-06Use logarithmic units for basic block alignment.Jakob Stoklund Olesen
This was actually a bit of a mess. TLI.setPrefLoopAlignment was clearly documented as taking log2(bytes) units, but the x86 target would still set a preferred loop alignment of '16'. CodePlacementOpt passed this number on to the basic block, and AsmPrinter interpreted it as bytes. Now both MachineFunction and MachineBasicBlock use logarithmic alignments. Obviously, MachineConstantPool still measures alignments in bytes, so we can emulate the thrill of using as. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145889 91177308-0d34-0410-b5e6-96231b3b80d8
