* Auto-upgrade the magic ".llvm.eh.catch.all.value" global toBill Wendling2010-09-10
| | | | | | | "llvm.eh.catch.all.value". Only the name needs to be changed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113600 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

* 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

Duplicating them into the end of the loop and the preheader means that we got a phi node in the header of the loop, which prevented LICM from hoisting them.
