2009-08-08eliminate TargetLoweringObjectFileSparc in favor of a TAI hook.Chris Lattner
A TAI hook is appropriate in this case because this is just an asm syntax issue, not a semantic difference. TLOF should model the semantics of the section. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78498 91177308-0d34-0410-b5e6-96231b3b80d8

Blackfin supports and/or/xor on i32 but not on i16. Teach DAGCombiner::SimplifyBinOpWithSameOpcodeHands to not produce illegal nodes after legalize ops. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78497 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-08now that getOrCreateSection is all object-file specific,Chris Lattner
give the impls an object-file-specific name. In the future they can take different arguments etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78495 91177308-0d34-0410-b5e6-96231b3b80d8

instructions, since they are in 64 bit mode with i64immSExt32 imms. JIT is not affected since it handles both word absolute relocations in the same way git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78479 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-08More ProfileInfo improvements.Daniel Dunbar
- Part of optimal static profiling patch sequence by Andreas Neustifter. - Store edge, block, and function information separately for each functions (instead of in one giant map). - Return frequencies as double instead of int, and use a sentinel value for missing information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78477 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-08ELF improvements:Bruno Cardoso Lopes

2009-08-08Clean out per-function data after the machine code verifier is done with it.Jakob Stoklund Olesen
Also don't dereference old pointers after they have been deleted causing random crashes when enabling the machine code verifier. Ahem... I have not included a test case for the crash. It hapened when enabling the verifier on CodeGen/X86/2009-08-06-branchfolder-crash.ll. The crash depends on an MBB being allocated at the same address as a previously deleted MBB. I don't think that can be reproduced reliably. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78472 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-08Update the machine code verifier to keep up with the scavenger.Jakob Stoklund Olesen
* Cleaner handling of <undef>. * <def> takes precedence over <def,dead>. * Implement the OK-to-redefine-a-register-that-was- live-in-but-has-not-been-used-before rule. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78467 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-08Remove RegisterScavenger::isSuperRegUsed(). This completely reverses the ↵Jakob Stoklund Olesen
mistaken commit r77904. Now there is no special treatment of instructions that redefine part of a super-register. Instead, the super-register is marked with <imp-use,kill> and <imp-def>. For instance, from LowerSubregs on ARM: subreg: CONVERTING: %Q1<def> = INSERT_SUBREG %Q1<undef>, %D1<kill>, 5 subreg: %D2<def> = FCPYD %D1<kill>, 14, %reg0, %Q1<imp-def> subreg: CONVERTING: %Q1<def> = INSERT_SUBREG %Q1, %D0<kill>, 6 subreg: %D3<def> = FCPYD %D0<kill>, 14, %reg0, %Q1<imp-use,kill>, %Q1<imp-def> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78466 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-08Simplify RegScavenger::forward a bit more.Jakob Stoklund Olesen
Verify that early clobber registers and their aliases are not used. All changes to RegsAvailable are now done as a transaction so the order of operands makes no difference. The included test case is from PR4686. It has behaviour that was dependent on the order of operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78465 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-08llvm-mc/AsmMatcher: Improve match code.Daniel Dunbar
- This doesn't actually improve the algorithm (its still linear), but the generated (match) code is now fairly compact and table driven. Still need a generic string matcher. - The table still needs to be compressed, this is quite simple to do and should shrink it to under 16k. - This also simplifies and restructures the code to make the match classes more explicit, in anticipation of resolving ambiguities. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78461 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-08Implement Neon VZIP and VUZP instructions. These are very similar to VTRN,Bob Wilson
so I generalized the class for VTRN in the .td file to handle all 3 of them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78460 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-08Implement Neon VTRN instructions. For now, anyway, these are selectedBob Wilson
directly from the intrinsics produced by the frontend. If it is more convenient to have a custom DAG node for using these to implement shuffles, we can add that later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78459 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-07To catch bugs like the one fixed inJeffrey Yasskin
http://llvm.org/viewvc/llvm-project?view=rev&revision=78127, I'm changing the ExecutionEngine's global mappings to hold AssertingVH<const GlobalValue>. That way, if unregistering a mapping fails to actually unregister it, we'll get an assert. Running the jit nightly tests didn't uncover any actual instances of the problem. This also uncovered the fact that AssertingVH<const X> didn't work, so I fixed that too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78400 91177308-0d34-0410-b5e6-96231b3b80d8
