| | | | | | | | | (The Ada bindings probably need it too, but all the obvious places to change say "do not edit this file".) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113618 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

* Discard metadata produced by LLVM 2.7. The value enumeration it usedDan Gohman2010-09-09
| | | | | | | | | | | | | | is different from what the code now uses in a two ways: NamedMDNodes were considered Values and included in the numbering, and the function-local metadata counter wasn't reset between functions. The later problem breaks lazy deserialization, so instead of trying to emulate the old numbering, just drop the old metadata. The only in-tree use case is debug info with LTO, where the QOI loss is considered acceptable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113557 91177308-0d34-0410-b5e6-96231b3b80d8

* What the loop unroller cares about, rather than just not unrolling loops ↵Owen Anderson2010-09-09
| | | | | | | | | | | | with calls, is not unrolling loops that contain calls that would be better off getting inlined. This mostly comes up when an interleaved devirtualization pass has devirtualized a call which the inliner will inline on a future pass. Thus, rather than blocking all loops containing calls, add a metric for "inline candidate calls" and block loops containing those instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113535 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert r113439, which relaxed the requirement that loops containing calls ↵Owen Anderson2010-09-09
