2013-03-28Target Cortex-A9 with NEON in PNaCl's LLC driver.JF Bastien
This is a follow-up to: https://codereview.chromium.org/12683004/ https://codereview.chromium.org/12969002/ And will enable optiomizations for our minimum platform when translating with default flags. At some point we'll probably want to specialize further by detecting, e.g. A15 and turning on VFP4, IDIV, etc...

2013-03-26PNaCl: Add ExpandGetElementPtr pass for converting GetElementPtr to arithmeticMark Seaborn
This is similar to the GEP handling in visitGetElementPtr() in lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp. Once this pass is enabled, it will simplify the language to reduce the set of constructs that a PNaCl translator needs to handle as part of a stable wire format for PNaCl.

This is in the process of being added upstream but the exact location is still debated and will take some time to settle. In the mean-time I'm adding it as a localmod so we can run our benchmarks effectively. Later this should be switched to the upstream implementation (or move to our own llc-replacement-driver).

2013-03-13ABI verifier: Add standalone tool pnacl-abicheckDerek Schuff
This CL adds a standalone tool pnacl-abicheck for checking the ABI validity of a bitcode file. It also adds a flag pnaclabi-verify to llc to enable the same checking in llc. It also improves the mechanism for handling and reporting validation errors and uses it in both tools.

2013-03-06Add an RPC to LLC.nexe to init with appended flags (vs set all flags).Jan Voung
This will take the default flags and append any extra flags. For now, this is only intended to support -O in the browser, and perhaps -mcpu=.*, -mattr=. We move the tuning parameters like -mcpu out of the default, so that a user does not end up setting the -mcpu more than once (which is disallowed). What does go into the default is -mtriple, which we may want to hard-code into the build somehow (but it's not yet clear how to do that cleanly). That way, a user does not need to specify that portion. We also hardcode the -sfi-* flags.

2013-02-25Provide workaround for PR 15130.Andrew Kaylor
This changes the RecordingMemoryManager in lli to use mapped memory rather than malloc to allocate memory for sections and uses a 'near' MemoryBlock to keep the allocations together.

2013-02-12llvm-sb: Remove non-streaming code path and write to file directly.Jan Voung
This avoids a use of the ParseIR/ParseIRFile API in the sandboxed translator. ParseIR and friends are flexible and handle LLVM .ll parsing. We only need to handle bitcode streams... By removing a use of ParseIR*, LTO will remove all LLParser-related code. Helps reduce the size of the sandboxed LLC by a couple hundred KB. Also, finally do the cleanup that makes the translator write to its output file directly, rather than writing to a string stream before finally writing the output to a file. May save a couple of MB of memory (size of the object file)... BUG= http://code.google.com/p/nativeclient/issues/detail?id=1222 Review URL: https://codereview.chromium.org/12224132

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.

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
