* Revert r110396 to fix buildbots.Owen Anderson2010-08-061-1/+1
| | | | llvm-svn: 110410
* Don't use PassInfo* as a type identifier for passes. Instead, use the ↵Owen Anderson2010-08-051-1/+1
| | | | | | | | address of the static ID member as the sole unique type identifier. Clean up APIs related to this change. llvm-svn: 110396
* Fix batch of converting RegisterPass<> to INTIALIZE_PASS().Owen Anderson2010-07-211-2/+2
| | | | llvm-svn: 109045
* eliminate CallInst::ArgOffsetGabor Greif2010-07-161-3/+3
| | | | llvm-svn: 108522
* use getArgOperand (corrected by CallInst::ArgOffset) instead of getOperandGabor Greif2010-06-301-1/+2
| | | | llvm-svn: 107273
* The hasMemory argument is irrelevant to how the argumentDale Johannesen2010-06-251-2/+1
| | | | | | | | | for an "i" constraint should get lowered; PR 6309. While this argument was passed around a lot, this is the only place it was used, so it goes away from a lot of other places. llvm-svn: 106893
* use ArgOperand APIGabor Greif2010-06-241-1/+1
| | | | llvm-svn: 106707
* Revert 101465, it broke internal OpenGL testing.Eric Christopher2010-04-161-1/+1
| | | | | | | Probably the best way to know that all getOperand() calls have been handled is to replace that API instead of updating. llvm-svn: 101579
* reapply r101434Gabor Greif2010-04-161-1/+1
| | | | | | | | | | | | | with a fix for self-hosting rotate CallInst operands, i.e. move callee to the back of the operand array the motivation for this patch are laid out in my mail to llvm-commits: more efficient access to operands and callee, faster callgraph-construction, smaller compiler binary llvm-svn: 101465
* back out r101423 and r101397, they break llvm-gcc self-host on darwin10Gabor Greif2010-04-161-1/+1
| | | | llvm-svn: 101434
* shift intrinsic operandGabor Greif2010-04-161-1/+1
| | | | llvm-svn: 101423
* Fix a nasty dangling-pointer heisenbug that couldDale Johannesen2010-03-311-1/+5
| | | | | | | | | | | | | | | | | | generate wrong code pretty much anywhere AFAICT. A case that hits the bug reproducibly is impossible, but the situation was like this: Addr = ... Store -> Addr Addr2 = GEP , 0, 0 Store -> Addr2 Handling the first store, the code changed replaced Addr with a sunkaddr and deleted Addr, but not its table entry. Code in OptimizedBlock replaced Addr2 with a bitcast; if that happened to reuse the memory of Addr, the old table entry was erroneously found when handling the second store. llvm-svn: 100044
* rename use_const_iterator to const_use_iterator for consistency's sakeGabor Greif2010-03-251-1/+1
| | | | llvm-svn: 99564
* Factor checked library call optimization into a common helper class and use itBenjamin Kramer2010-03-121-96/+19
| | | | | | to unify the almost identical code in CodeGenPrepare and InstCombineCalls. llvm-svn: 98338
* stpcpy is so similar to strcpy, it doesn't deserve a complete copy of the ↵Benjamin Kramer2010-03-111-15/+3
| | | | | | __strcpy_chk -> strcpy code. llvm-svn: 98284
* Lower stpcpy_chk when possible.Eric Christopher2010-03-111-6/+9
| | | | llvm-svn: 98274
* Do some final lowering in CodeGenPrepare of _chk calls similar toEric Christopher2010-03-111-0/+134
| | | | | | | | that in InstCombineCalls. More call lowering needed. llvm-svn: 98228
* There are two ways of checking for a given type, for example isa<PointerType>(T)Duncan Sands2010-02-161-2/+2
| | | | | | | and T->isPointerTy(). Convert most instances of the first form to the second form. Requested by Chris. llvm-svn: 96344
* remove dead code.Chris Lattner2010-02-131-46/+7
| | | | llvm-svn: 96109
* Split some code out to a helper function (FindReusablePredBB)Chris Lattner2010-02-131-50/+72
| | | | | | | | | | | | and add a doxygen comment. Cache the phi entry to avoid doing tons of PHINode::getBasicBlockIndex calls in the common case. On my insane testcase from re2c, this speeds up CGP from 617.4s to 7.9s (78x). llvm-svn: 96083
* speed up CGP a bit by scanning predecessors through phi operandsChris Lattner2010-02-131-22/+22
| | | | | | instead of with pred_begin/end. llvm-svn: 96078
* Implement releaseMemory in CodeGenPrepare and free the BackEdgesDan Gohman2010-02-051-0/+4
| | | | | | | container data. This prevents it from holding onto dangling pointers and potentially behaving unpredictably. llvm-svn: 95409
* When doing address-mode sinking, expand the base register first, ratherDan Gohman2010-01-191-12/+17
| | | | | | | | | | | | than the scaled register. This makes it more likely that subsequent AddrModeMatcher queries will match the new address the same way as the old, instead of accidentally matching what had been the base register as the new scaled register, and then failing to match the scaled register. This fixes some problems with address-mode sinking multiple muls into a block, which will be a lot more common with some upcoming LoopStrengthReduction changes. llvm-svn: 93935
* Change errs() to dbgs().David Greene2010-01-051-6/+6

* llvm::SplitEdge should refuse to split an edge from an indirectbr.Chris Lattner2009-10-311-1/+2
| | | | | | Fix CodeGenPrepare to not try to split edges from indirectbr. llvm-svn: 85690
* Move zext and sext casts fed by loads into the same block as theDan Gohman2009-10-161-1/+41

* eliminate the "Value" printing methods that print to a std::ostream.Chris Lattner2009-08-231-3/+3
| | | | | | This required converting a bunch of stuff off DOUT and other cleanups. llvm-svn: 79819
* Push LLVMContexts through the IntegerType APIs.Owen Anderson2009-08-131-1/+2
| | | | llvm-svn: 78948

* Convert a few more uses of llvm/Support/Streams.h to raw_ostream.Dan Gohman2009-07-251-5/+6
| | | | llvm-svn: 77033
* Revert the ConstantInt constructors back to their 2.5 forms where possible, ↵Owen Anderson2009-07-241-2/+2
