2011-02-07Teach ARM/MC/ELF about gcc compatible reloc output to get past odd linkageJason W Kim
failures with relocations. The code committed is a first cut at compatibility for emitted relocations in ELF .o. Why do this? because existing ARM tools like emitting relocs symbols as explicit relocations, not as section-offset relocs. Result is that with these changes, 1) relocs are now substantially identical what to gcc outputs. 2) larger apps (including many spec2k tests) compile, cross-link, and pass Added reminder fixme to tests for future conversion to .s form. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124996 91177308-0d34-0410-b5e6-96231b3b80d8

<rdar://problem/8959122> illegal register operands for UMULL instruction in cfrac nightly test I'm stil working on a unit test, but the case is: rx = movcc rx, r3 r2 = ldr r2, r3 = umull r2, r2 The anti-dep breaker should not convert this into an illegal instruction: r2, r2 = umull git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124932 91177308-0d34-0410-b5e6-96231b3b80d8

If the interference overlaps the instruction, we cannot separate it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124918 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-05Add assertions to verify that the new interval is clear of the interference.Jakob Stoklund Olesen
If these inequalities don't hold, we are creating a live range split that won't allocate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124917 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-05Rewrite how the indirect call bonus is handled. This now works by:Eric Christopher
a) Making it a per call site bonus for functions that we can move from indirect to direct calls. b) Reduces the bonus from 500 to 100 per call site. c) Subtracts the size of the possible newly inlineable call from the bonus to only add a bonus if we can inline a small function to devirtualize it. Also changes the bonus from a positive that's subtracted to a negative that's added. Fixes the remainder of rdar://8546196 by reducing the object file size after inlining by 84%. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124916 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-04[AVX] Add some utilities to insert and extract 128-bit subvectors.David Greene
This allows us to easily support 256-bit operations that don't have native 256-bit support. This applies to integer operations, certain types of shuffles and various othher things. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124910 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-04Apparently, it is possible for a block with a landing pad successor to have ↵Jakob Stoklund Olesen
no calls. In that case we simply ignore the landing pad and split live ranges before the first terminator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124907 91177308-0d34-0410-b5e6-96231b3b80d8

purpose. Fixes PR9080! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124903 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-04Be more accurate about live range splitting at the end of blocks.Jakob Stoklund Olesen
If interference reaches the last split point, it is effectively live out and should be marked as 'MustSpill'. This can make a difference when the terminator uses a register. There is no way that register can be reused in the outgoing CFG bundle, even if it isn't live out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124900 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-04Teach ARM/MC/ELF to handle R_ARM_JUMP24 relocation type for conditional jumps.Jason W Kim
(yes, this is different from R_ARM_CALL) - Adds a new method getARMBranchTargetOpValue() which handles the necessary distinction between the conditional and unconditional br/bl needed for ARM/ELF At least for ARM mode, the needed fixup for conditional versus unconditional br/bl is identical, but the ARM docs and existing ARM tools expect this reloc type... Added a few FIXME's for future naming fixups in ARMInstrInfo.td git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124895 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-04Add LiveIntervals::getLastSplitPoint().Jakob Stoklund Olesen
A live range cannot be split everywhere in a basic block. A split must go before the first terminator, and if the variable is live into a landing pad, the split must happen before the call that can throw. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124894 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-04Verify that one of the ranges produced by region splitting is allocatable.Jakob Stoklund Olesen
We should not be attempting a region split if it won't lead to at least one directly allocatable interval. That could cause infinite splitting loops. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124893 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-04Introducing a new method of tracking register pressure. We can'tAndrew Trick
precisely track pressure on a selection DAG, but we can at least keep it balanced. This design accounts for various interesting aspects of selection DAGS: register and subregister copies, glued nodes, dead nodes, unused registers, etc. Added SUnit::NumRegDefsLeft and ScheduleDAGSDNodes::RegDefIter. Note: I disabled PrescheduleNodesWithMultipleUses when register pressure is enabled, based on no evidence other than I don't think it makes sense to have both enabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124853 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-04DebugLoc associated with a machine instruction is used to emit location ↵Devang Patel
entries. DebugLoc associated with a DBG_VALUE is used to identify lexical scope of the variable. After register allocation, while inserting DBG_VALUE remember original debug location for the first instruction and reuse it, otherwise dwarf writer may be mislead in identifying the variable's scope. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124845 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-04Also compute interference intervals for blocks with no uses.Jakob Stoklund Olesen
When the live range is live through a block that doesn't use the register, but that has interference, region splitting wants to split at the top and bottom of the basic block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124839 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-04Verify kill flags conservatively.Jakob Stoklund Olesen
Allow a live range to end with a kill flag, but don't allow a kill flag that doesn't end the live range. This makes the machine code verifier more useful during register allocation when kill flag computation is deferred. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124838 91177308-0d34-0410-b5e6-96231b3b80d8
