* Add the AddLandingPadInfo function.Bill Wendling2011-07-282-0/+39
| | | | | | | AddLandingPadInfo takes a landingpad instruction and grabs all of the information from it that it needs for EH table generation. llvm-svn: 136429
* Change LBH_TAKEN_WEIGHT to 124 (from 128). Right now, sum ofJakub Staszak2011-07-281-4/+4
| | | | | | | LBH_TAKEN_WEIGHT + LBH_NONTAKEN_WEIGHT = 128 which in _most_ cases reduce number of rounding errors. llvm-svn: 136428
* PLD and PLI are not predicable in ARM mode.Jim Grosbach2011-07-281-0/+1

* CBZ/CBNZ are Thumb2 only. No need for ARM mode tests for them.Jim Grosbach2011-07-281-4/+0
| | | | llvm-svn: 136408
* ARM assembly parsing and encoding for BLX (immediate).Jim Grosbach2011-07-283-3/+16
| | | | | | | | Add parsing support for BLX (immediate). Since the register operand version is predicated and the label operand version is not, we have to use some special handling to get the operand list right for matching. llvm-svn: 136406
* Enhance the fixed-length decoder emitter to support parsing scattered fields.Owen Anderson2011-07-282-80/+111

* LangRef and basic memory-representation/reading/writing for 'cmpxchg' andEli Friedman2011-07-2818-43/+946
| | | | | | | | | | | | | | | | | | | | | 'atomicrmw' instructions, which allow representing all the current atomic rmw intrinsics. The allowed operands for these instructions are heavily restricted at the moment; we can probably loosen it a bit, but supporting general first-class types (where it makes sense) might get a bit complicated, given how SelectionDAG works. As an initial cut, these operations do not support specifying an alignment, but it would be possible to add if we think it's useful. Specifying an alignment lower than the natural alignment would be essentially impossible to support on anything other than x86, but specifying a greater alignment would be possible. I can't think of any useful optimizations which would use that information, but maybe someone else has ideas. Optimizer/codegen support coming soon. llvm-svn: 136404
* If run with -debug give more information about Cyclic Probability.Jakub Staszak2011-07-281-0/+2

* Handle REG_SEQUENCE with implicitly defined operands.Jakob Stoklund Olesen2011-07-282-0/+27
| | | | | | | | | | | | | Code like that would only be produced by bugpoint, but we should still handle it correctly. When a register is defined by a REG_SEQUENCE of undefs, the register itself is undef. Previously, we would create a register with uses but no defs. Fixes part of PR10520. llvm-svn: 136401
* Remove obsolete FIXME reference in comment.Jim Grosbach2011-07-281-1/+1
| | | | llvm-svn: 136400
* ARM assembly parsing and encoding for BFC and BFI.Jim Grosbach2011-07-283-2/+130
| | | | | | | Add parsing support that handles converting the lsb+width source into the odd way we represent the instruction (an inverted bitfield mask). llvm-svn: 136399
* Add InEdges (edges from header to the loop) in Loop Branch Heuristics, soJakub Staszak2011-07-281-0/+17

* Reverse order of RS_Split live ranges under -compact-regions.Jakob Stoklund Olesen2011-07-281-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two conflicting strategies in play: - Under high register pressure, we want to assign large live ranges first. Smaller live ranges are easier to place afterwards. - Live range splitting is guided by interference, so splitting should be deferred until interference is as realistic as possible. With the recent changes to the live range stages, and with compact regions enabled, it is less traumatic to split a live range too early. If some of the split products were too big, they can often be split again. By reversing the RS_Split order, we get this queue order: 1. Normal live ranges, large to small. 2. RS_Split live ranges, large to small. The large-to-small order improves RAGreedy's puzzle solving skills under high register pressure. It may cause a bit more iterated splitting, but we handle that better now. With this change, -compact-regions is mostly an improvement on SPEC. llvm-svn: 136388
* Initial code to convert ResumeInsts into calls to _Unwind_Resume.Bill Wendling2011-07-281-1/+57

| | | | | | | | | | | | | | | | | | | LLVM*AsmPrinter. GenLibDeps.pl fails to detect vtable references. As this is the only referenced symbol from LLVM*Desc to LLVM*AsmPrinter on optimized builds, the algorithm that creates the list of libraries to be linked into tools doesn't know about the dependency and sometimes places the libraries on the wrong order, yielding error messages like this: ../../lib/libLLVMARMDesc.a(ARMMCTargetDesc.cpp.o): In function `llvm::ARMInstPrinter::ARMInstPrinter(llvm::MCAsmInfo const&)': ARMMCTargetDesc.cpp:(.text._ZN4llvm14ARMInstPrinterC1ERKNS_9MCAsmInfoE [llvm::ARMInstPrinter::ARMInstPrinter(llvm::MCAsmInfo const&)]+0x2a): undefined reference to `vtable for llvm::ARMInstPrinter' llvm-svn: 136328
