2012-01-16MCJIT support for non-function sections.Jim Grosbach
Move to a by-section allocation and relocation scheme. This allows better support for sections which do not contain externally visible symbols. Flesh out the relocation address vs. local storage address separation a bit more as well. Remote process JITs use this to tell the relocation resolution code where the code will live when it executes. The startFunctionBody/endFunctionBody interfaces to the JIT and the memory manager are deprecated. They'll stick around for as long as the old JIT does, but the MCJIT doesn't use them anymore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148258 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-02Undo the hack in r147427 and move this unittest to a better home. ThisChandler Carruth
is testing the bitcode reader's functionality, not VMCore's. Add the what is a hope sufficient build system mojo to build and run a new unittest. Also clean up some of the test's naming. The goal for the file should be to unittest the Bitcode Reader, and this is just one particular test among potentially many in the future. Also, reverse my position and relegate the PR# to a comment, but stash the comment on the same line as the test name so it doesn't get lost. This makes the code more self-documenting hopefully w/o losing track of the PR number. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147431 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-02Fix unittest makefile after r147425. This should unbreak the makefileChandler Carruth
build. This didn't show up in the CMake build because the CMake build for the unittests is rather poorly factored. This probably isn't the correct fix. This should be a bitcode reader unittest not a VMCore unittest. I'll move it and clean various parts of the unittest up in a follow-up patch, but I wanted to unbreak the bots. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147427 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-21Changes the JSON parser to use the SourceMgr.Manuel Klimek
Diagnostics are now emitted via the SourceMgr and we use MemoryBuffer for buffer management. Switched the code to make use of the trailing '0' that MemoryBuffer guarantees where it makes sense. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147063 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-17As Doug pointed out (and I really should know), it is perfectly easy toChandler Carruth
make VariadicFunction actually be trivial. Do so, and also make it look more like your standard trivial functor by making it a struct with no access specifiers.

2011-12-16Add a generic collection of class templates to ADT for buildingChandler Carruth
variadic-like functions in C++98. See the comments in the header file for a more detailed description of how these work. We plan to use these extensively in the AST matching library. This code and idea were originally authored by Zhanyong Wan. I've condensed it using macros to reduce repeatition and adjusted it to fit better with LLVM's ADT.

These annotations are disabled entirely when either ENABLE_THREADS is off, or building a release build. When enabled, they add calls to functions with no statements to ManagedStatic's getters. Use these annotations to inform tsan that the race used inside ManagedStatic initialization is actually benign.

does. Enhance the X86 asmparser to produce ranges in the one case that was annoying me, for example: test.s:10:15: error: invalid operand for instruction movl 0(%rax), 0(%edx) ^~~~~~~ It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use ranges where appropriate if someone is interested. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142106 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-15Add a bad char heuristic to StringRef::find.Benjamin Kramer
Based on Horspool's simplified version of Boyer-Moore. We use a constant-sized table of uint8_ts to keep cache thrashing low, needles bigger than 255 bytes are uncommon anyways. The worst case is still O(n*m) but we do a lot better on the average case now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142061 91177308-0d34-0410-b5e6-96231b3b80d8
