* Teach instCombine to remove malloc+free if malloc's only uses are comparisonsDuncan Sands2010-05-271-29/+0

* Revert 101465, it broke internal OpenGL testing.Eric Christopher2010-04-161-3/+3
| | | | | | | 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 Greif2010-04-161-3/+3
| | | | | | | | | | | | | 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 Greif2010-04-161-3/+3

* Add variants of ult, ule, etc. which take a uint64_t RHS, for convenience.Dan Gohman2010-04-081-1/+1

* Fix PR6503. This turned into a much more interesting and nasty bug. Various Chris Lattner2010-03-051-8/+9
| | | | | | | | | | | parts of the cmp|cmp and cmp&cmp folding logic wasn't prepared for vectors (unrelated to the bug but noticed while in the code) and the code was *definitely* not safe to use by the (cast icmp)|(cast icmp) handling logic that I added in r95855. Fix all this up by changing the various routines to more consistently use IRBuilder and not pass in the I which had the wrong type. llvm-svn: 97801
* Fix indentation.Dan Gohman2010-02-241-10/+10

* There are two ways of checking for a given type, for example isa<PointerType>(T)Duncan Sands2010-02-161-1/+1
| | | | | | | and T->isPointerTy(). Convert most instances of the first form to the second form. Requested by Chris. llvm-svn: 96344
* Uniformize the names of type predicates: rather than having isFloatTy andDuncan Sands2010-02-151-2/+2

* Truncate GEP indexes larger than the pointer size down to pointer sizeChris Lattner2010-01-041-0/+9
| | | | | | | | | | | when doing this transform if the GEP is not inbounds. No testcase because it is very difficult to trigger this: instcombine already canonicalizes GEP indices to pointer size, so it relies specific permutations of the instcombine worklist. Thanks to Duncan for pointing this possible problem out. llvm-svn: 92495
