2010-09-10Makefile.rules: LOADABLE_MODULE/Win32: "all" components may be linkedNAKAMURA Takumi
only when ENABLE_SHARED=1. Loadable module for Win32 requires all symbols resolved for linking. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113579 91177308-0d34-0410-b5e6-96231b3b80d8

Building archive would be executed due to definition of BUILD_ARCHIVE, even if BUILD_ARCHIVE = "0". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113578 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-10Fix test so it passes on non-Darwin hosts.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113577 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-10Fix merging base-updates for VLDM/VSTM: Before I switched these instructionsBob Wilson
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
2010-09-10Teach if-converter to be more careful with predicating instructions that wouldEvan Cheng
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

2010-09-0964-bit fp loads can come straight out of the constant pool, not asEric Christopher
bad as I'd thought. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113561 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-09Discard metadata produced by LLVM 2.7. The value enumeration it usedDan Gohman
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
2010-09-09llvm-mc: Don't crash when using -n and we see a directive before the initial ↵Daniel Dunbar
section. - This is annoying, because we have to scatter this check everywhere that could emit real data, but I see no better solution. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113552 91177308-0d34-0410-b5e6-96231b3b80d8

Truncate when truncating, extend when extending. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113536 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-09What the loop unroller cares about, rather than just not unrolling loops ↵Owen Anderson
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

2010-09-09Revert r113439, which relaxed the requirement that loops containing calls ↵Owen Anderson
cannot be unrolled. After some discussion, there seems to be a better way to achieve the same effect. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113528 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-09Use code-size reduction metrics to estimate the amount of savings we'll get ↵Owen Anderson
when we unroll a loop. Next step is to recalculate the threshold values given this new heuristic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113525 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-09For each instruction itinerary class, specify the number of micro-ops eachEvan Cheng
instruction in the class would be decoded to. Or zero if the number of uOPs must be determined dynamically. This will be used to determine the cost-effectiveness of predicating a micro-coded instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113513 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-09Refactor code-size reduction estimation methods out of InlineCostAnalyzer ↵Owen Anderson
and into CodeMetrics. They don't use any InlineCostAnalyzer state, and are useful for other clients who don't necessarily want to use all of InlineCostAnalyzer's logic, some of which is fairly inlining-specific. No intended functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113499 91177308-0d34-0410-b5e6-96231b3b80d8
