| | | | | | | | | | instcombine transforms to expose greater opportunities for store narrowing in codegen. This patch fixes a potential infinite loop in instcombine caused by one of the introduced transforms being overly aggressive. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113763 91177308-0d34-0410-b5e6-96231b3b80d8

* Invert and-of-or into or-of-and when doing so would allow us to clear bits ↵Owen Anderson2010-09-11
| | | | | | | | | | | | | | | of the and's mask. This can result in increased opportunities for store narrowing in code generation. Update a number of tests for this change. This fixes <rdar://problem/8285027>. Additionally, because this inverts the order of ors and ands, some patterns for optimizing or-of-and-of-or no longer fire in instances where they did originally. Add a simple transform which recaptures most of these opportunities: if we have an or-of-constant-or and have failed to fold away the inner or, commute the order of the two ors, to give the non-constant or a chance for simplification instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113679 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix merging base-updates for VLDM/VSTM: Before I switched these instructionsBob Wilson2010-09-10
| | | | | | | | | | | to use AddrMode4, there was a count of the registers stored in one of the operands. I changed that to just count the operands but forgot to adjust for the size of D registers. This was noticed by Evan as a performance problem but it is a potential correctness bug as well, since it is possible that this could merge a base update with a non-matching immediate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113576 91177308-0d34-0410-b5e6-96231b3b80d8
* Teach if-converter to be more careful with predicating instructions that wouldEvan Cheng2010-09-10
| | | | | | | | | | | | take multiple cycles to decode. For the current if-converter clients (actually only ARM), the instructions that are predicated on false are not nops. They would still take machine cycles to decode. Micro-coded instructions such as LDM / STM can potentially take multiple cycles to decode. If-converter should take treat them as non-micro-coded simple instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113570 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix NEON VLD pseudo instruction itineraries that were incorrectly copied fromBob Wilson2010-09-09

* Relax the "don't unroll loops containing calls" rule. Instead, when a loop ↵Owen Anderson2010-09-08

Basically, for loops containing calls, unrolling can still be profitable as long as the loop is REALLY small. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113439 91177308-0d34-0410-b5e6-96231b3b80d8
