* To catch bugs like the one fixed inJeffrey Yasskin2009-08-071-13/+18
| | | | | | | | | | | | | | 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

* SIV/MIV classification for LDA.Andreas Bolka2009-08-071-6/+35
| | | | | | | | | | LoopDependenceAnalysis::getLoops is currently O(N*M) for a loop-nest of depth N and a compound SCEV of M atomic SCEVs. As both N and M will typically be very small, this should not be a problem. If it turns out to be one, rewriting getLoops as SCEVVisitor will reduce complexity to O(M). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78394 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-mc/AsmMatcher: Move to a slightly more sane matching design.Daniel Dunbar2009-08-071-139/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Still not very sane, but a least its not 60k lines on X86. :) - In terms of correctness, currently some things are hard wired for X86, and we still don't properly resolve ambiguities (this is ignoring the instructions we don't even match due to funny .td stuff or other corner cases). The high level changes: 1. Represent tokens which are significant for matching explicitly as separate operands. This uniformly handles not only the instruction mnemonic, but also 'signficiant' syntax like the '*' in "call * ...". 2. Separate the matching of operands to an instruction from the construction of the MCInst. In theory this can be done during matching, but since the number of variations is small I think it makes sense to decompose the problems. 3. Improved a few of the mechanisms to at least successfully flatten / tokenize the assembly strings for PowerPC and ARM. 4. The comment at the top of AsmMatcherEmitter.cpp explains the approach I'm moving towards for handling ambiguous instructions. The high-bit is to infer a partial ordering of the operand classes (and force the user to specify one if we can't) and use that to resolve ambiguities. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78378 91177308-0d34-0410-b5e6-96231b3b80d8

* It turns out most of the thumb2 instructions are not allowed to touch SP. ↵Evan Cheng2009-08-0710-70/+346
| | | | | | | | | | | The semantics of such instructions are unpredictable. We have just been lucky that tests have been passing. This patch takes pain to ensure all the PEI lowering code does the right thing when lowering frame indices, insert code to manipulate stack pointers, etc. It's also custom lowering dynamic stack alloc into pseudo instructions so we can insert the right instructions at scheduling time. This fixes PR4659 and PR4682. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78361 91177308-0d34-0410-b5e6-96231b3b80d8
