* Revert "Add missing #include, found by modules build."Mehdi Amini2015-10-211-82/+8
| | | | | | | | | | | This reverts commit r250239. It seems unwanted changes got committed here, and part of the patch does not seem correct. For instance RoundUpToAlignment() is called without its returned value actually used. From: Mehdi Amini <mehdi.amini@apple.com> llvm-svn: 250882
* bugpoint: Remove implicit ilist iterator conversions, NFCDuncan P. N. Exon Smith2015-10-203-56/+47
| | | | | | | | This is the last of the implicit ilist iterator conversions in LLVM. Still up for debate whether we let these bitrot back: http://lists.llvm.org/pipermail/llvm-dev/2015-October/091617.html llvm-svn: 250852

* [Orc] Add support for emitting indirect stubs directly into the JIT target'sLang Hames2015-10-192-18/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | memory, rather than representing the stubs in IR. Update the CompileOnDemand layer to use this functionality. Directly emitting stubs is much cheaper than building them in IR and codegen'ing them (see below). It also plays well with remote JITing - stubs can be emitted directly in the target process, rather than having to send them over the wire. The downsides are: (1) Care must be taken when resolving symbols, as stub symbols are held in a separate symbol table. This is only a problem for layer writers and other people using this API directly. The CompileOnDemand layer hides this detail. (2) Aliases of function stubs can't be symbolic any more (since there's no symbol definition in IR), but must be converted into a constant pointer expression. This means that modules containing aliases of stubs cannot be cached. In practice this is unlikely to be a problem: There's no benefit to caching such a module anyway. On balance I think the extra performance is more than worth the trade-offs: In a simple stress test with 10000 dummy functions requiring stubs and a single executed "hello world" main function, directly emitting stubs reduced user time for JITing / executing by over 90% (1.5s for IR stubs vs 0.1s for direct emission). llvm-svn: 250712

* llvm-lto support for generating combined function indexesTeresa Johnson2015-10-193-1/+68
| | | | | | | | | | | | | | | | | Summary: This patch adds support to llvm-lto that mirrors the support added by r249270 to the gold plugin. This enables better testing of combined index generation for ThinLTO. Added a new test, and this support will be used in the test in D13515.

* [CMake] [Darwin] Add support for generating Xcode-compatible toolchains that ↵Chris Bieneman2015-10-151-0/+72
| | | | | | | | | | | | | | | | | | | xcodebuild and xcrun can search Summary: Sometimes you want to install a custom compiler and use it like the system compiler without overriding the system compiler. This patch lets you create xctoolchains that the darwin command line tools can use. To use this patch set LLVM_CREATE_XCODE_TOOLCHAIN=On in your CMake invocation and build the `install-code-toolchain` target. After installation you can set the envar EXTERNAL_TOOLCHAINS_DIR to your installed Toolchains directory, and the TOOLCHAINS envar to the toolchain identifier (ex org.llvm.3.8.0svn). This will then cause /usr/bin/clang to call your newly installed clang.

* [JIT] TrivialMemoryManager: Fail if we can't allocate memory.Davide Italiano2015-10-151-2/+8
| | | | | | | | | | | | | TrivialMemoryManager currently doesn't check the return type of AllocateRWX -- and returns a 'null' MemoryBlock to its caller. As pointed out by Lang, this exposes some serious issues with the MemoryManager interface. There's, in fact, no way to report back an error to clients rather than aborting in case memory can't be allocated. Eventually the interface will grow to support this, but for now, fail sooner rather than later. Differential Revision: http://reviews.llvm.org/D13627 llvm-svn: 250350
* [Bugpoint] Use 'CC' instead of 'GCC' for variable naming.Davide Italiano2015-10-146-149/+149

* [dsymutil] Try to find lipo first besides dsymutil before looking up the PATH.Frederic Riss2015-10-083-6/+12
| | | | | | | | Even if we don't have it in PATH, lipo should usually exist in the same directory as dsymutil. Keep the fallback looking up the PATH, it's very useful when testing a non-installed executable. llvm-svn: 249762
* Re-apply r249644: Handle inline stacks in gcov-encoded sample profiles.Diego Novillo2015-10-081-1/+7
| | | | | | | | | | | | | This fixes memory allocation problems by making the merge operation keep the profile readers around until the merged profile has been emitted. This is needed to prevent the inlined function names to disappear from the function profiles. Since all the names are kept as references, once the reader disappears, the names are also deallocated. Additionally, XFAIL on big-endian architectures. The test case uses a gcov file generated on a little-endian system. llvm-svn: 249724

* Stop linking all target libraries in llvm-nm and llvm-objdump.Pete Cooper2015-10-073-3/+7
| | | | | | | | | | llvm-nm only needs the target to parse module level assembly in bitcode. It doesn't need a disassembler or codegen. llvm-objdump needs to be able to disassemble a file, but doesn't need asm parsers or codegen. This reduces the sizes of these tools by a few MB each, depending on how many backends are linked in. llvm-svn: 249632
