2013-02-03[Object][Archive] Improve performance.Michael J. Spencer
Improve performance of iterating over children and accessing the member file buffer by caching the file size and moving code out to the header. This also makes getBuffer return a StringRef instead of a MemoryBuffer. Both fixing a memory leak and removing a malloc. This takes getBuffer from ~10% of the time in lld to unmeasurable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174272 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-02Remove the (apparently) unnecessary debug info metadata indirection.David Blaikie
The main lists of debug info metadata attached to the compile_unit had an extra layer of metadata nodes they went through for no apparent reason. This patch removes that (& still passes just as much of the GDB 7.5 test suite). If anyone can show evidence as to why these extra metadata nodes are there I'm open to reverting this patch & documenting why they're there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174266 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-02This patch makes "&Cls::purevfn" not an odr use. This isn't what the standardNick Lewycky

2013-02-01This patch aims to improve compile time performance by increasingPreston Gurd
the SCEV vector size in LoopStrengthReduce. It is observed that the BaseRegs vector size is 4 in most cases, and elements are frequently copied when it is initialized as SmallVector<const SCEV *, 2> BaseRegs. Our benchmark results show that the compilation time performance improved by ~0.5%.

2013-02-01Rewrite instsimplify's handling if icmp on pointer values to remove theDan Gohman

2013-01-31Switch the code added in r173885 to use the new, shiny RTTIChandler Carruth
infrastructure on MCStreamer to test for whether there is an MCELFStreamer object available. This is just a cleanup on the AsmPrinter side of things, moving ad-hoc tests of random APIs to a direct type query. But the AsmParser completely broken. There were no tests, it just blindly cast its streamer to an MCELFStreamer and started manipulating it. I don't have a test case -- this actually failed on LLVM's own regression test suite. Unfortunately the failure only appears when the stars, compilers, and runtime align to misbehave when we read a pointer to a formatted_raw_ostream as-if it were an MCAssembler. =/ UBSan would catch this immediately. Many thanks to Matt for doing about 80% of the debugging work here in GDB, Jim for helping to explain how exactly to fix this, and others for putting up with the hair pulling that ensued during debugging it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174118 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-31Give the MCStreamer class hierarchy LLVM RTTI facilities for use withChandler Carruth
isa<> and dyn_cast<>. In several places, code is already hacking around the absence of this, and there seem to be several interfaces that might be lifted and/or devirtualized using this. This change was based on a discussion with Jim Grosbach about how best to handle testing for specific MCStreamer subclasses. He said that this was the correct end state, and everything else was too hacky so I decided to just make it so. No functionality should be changed here, this is just threading the kind through all the constructors and setting up the classof overloads. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174113 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-31Remove the AttrBuilder form of the Attribute::get creators.Bill Wendling
The AttrBuilder is for building a collection of attributes. The Attribute object holds only one attribute. So it's not really useful for the Attribute object to have a creator which takes an AttrBuilder. This has two fallouts: 1. The AttrBuilder no longer holds its internal attributes in a bit-mask form. 2. The attributes are now ordered alphabetically (hence why the tests have changed). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174110 91177308-0d34-0410-b5e6-96231b3b80d8
