* [mips] Remove Triple:mips from SupportedArchs in MCJIT unittestsAkira Hatanaka2013-06-20
| | | | | | | | | | | | | | | | MIPS does not handle multiple relocations correctly, so two tests from the unittests are expected to fail. These are: - MCJITTest.return_global and - MCJITTest.multiple_functions. Until the multiple relocations are fixed, XFAIL the MCJIT unittests for MIPS. This issue is tracked as Bug 16250. Patch by Petar Jovanovic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184461 91177308-0d34-0410-b5e6-96231b3b80d8

* Alternative fix for problem addressed in r182233Ulrich Weigand2013-05-21
| | | | | | | | | | | | | | | | | | | Revision r182233 partially reverted the change in r181200 to simplify JIT unif test #ifdefs, because that change caused a link error on some host operating systems where the export list requires the following symbols to be defined: JITTest_AvailableExternallyFunction JITTest_AvailableExternallyGlobal As discussed on the list, the commit reverts r182233 (and re-installs the full r181200 change), and instead fixes the link problem by moving those two symbols to the top of the file and unconditionally defining them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182367 91177308-0d34-0410-b5e6-96231b3b80d8
* Partially revert change in r181200 that tried to simplify JIT unit test #ifdefs.Bob Wilson2013-05-20
| | | | | | | | | | | | | | The export list for this test requires the following symbols to be available: JITTest_AvailableExternallyFunction JITTest_AvailableExternallyGlobal The change in r181200 commented them out, which caused the test to fail to link, at least on Darwin. I have only reverted the change for arm, since I can't test the other targets and since it sounds like that change was fixing real problems for those other targets. It should be possible to rearrange the code to keep those definitions outside the #ifdefs, but that should be done by someone who can reproduce the problems that r181200 was trying to fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182233 91177308-0d34-0410-b5e6-96231b3b80d8

* Use only explicit bool conversion operatorsDavid Blaikie2013-05-15
| | | | | | | | | | | | | | | | | | | | | | | BitVector/SmallBitVector::reference::operator bool remain implicit since they model more exactly a bool, rather than something else that can be boolean tested. The most common (non-buggy) case are where such objects are used as return expressions in bool-returning functions or as boolean function arguments. In those cases I've used (& added if necessary) a named function to provide the equivalent (or sometimes negative, depending on convenient wording) test. One behavior change (YAMLParser) was made, though no test case is included as I'm not sure how to reach that code path. Essentially any comparison of llvm::yaml::document_iterators would be invalid if neither iterator was at the end. This helped uncover a couple of bugs in Clang - test cases provided for those in a separate commit along with similar changes to `operator bool` instances in Clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181868 91177308-0d34-0410-b5e6-96231b3b80d8
* SectionMemoryManager shouldn't be a JITMemoryManager. Previously, the Filip Pizlo2013-05-14
| | | | | | | | | | | | | | | | | | | EngineBuilder interface required a JITMemoryManager even if it was being used to construct an MCJIT. But the MCJIT actually wants a RTDyldMemoryManager. Consequently, the SectionMemoryManager, which is meant for MCJIT, derived from the JITMemoryManager and then stubbed out a bunch of JITMemoryManager methods that weren't relevant to the MCJIT. This patch fixes the situation: it teaches the EngineBuilder that RTDyldMemoryManager is a supertype of JITMemoryManager, and that it's appropriate to pass a RTDyldMemoryManager instead of a JITMemoryManager if we're using the MCJIT. This allows us to remove the stub methods from SectionMemoryManager, and make SectionMemoryManager a direct subtype of RTDyldMemoryManager. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181820 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix MCJITCAPITest.cpp unit test on Windows.Andrew Kaylor2013-05-10
| | | | | | MCJIT on Windows requires an explicit target triple with "-elf" appended to generate objects in ELF format. The common test framework was setting up this triple, but it wasn't passed to the C API in the test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181614 91177308-0d34-0410-b5e6-96231b3b80d8

* [SystemZ] Set up JIT/MCJIT test casesUlrich Weigand2013-05-06
| | | | | | | | | | | | | This patch adds the necessary configuration bits and #ifdef's to set up the JIT/MCJIT test cases for SystemZ. Like other recent targets, we do fully support MCJIT, but do not support the old JIT at all. Set up the lit config files accordingly, and disable old-JIT unit tests. Patch by Richard Sandiford. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181207 91177308-0d34-0410-b5e6-96231b3b80d8
* Simplify JIT unit test #ifdefsUlrich Weigand2013-05-06
| | | | | | | | | | | | | | | | | | | | | Several platforms need to disable all old-JIT unit tests, since they only support the new MCJIT. This currently done via #ifdef'ing out those tests in the ExecutionEngine/JIT/*.cpp files. As those #ifdef's have grown historically, we now have a number of repeated directives which -in total- cover nearly the whole file, but leave a couple of helper functions out. When building the tests with clang itself, those helper functions now cause spurious "unused function" warnings. To fix those warnings, and also to remove the duplicate #ifdef conditions and make it easier to disable the tests for a new target, this patch consolidates the #ifdefs into a single one per file, which covers all the tests including all helper routines. Tested on PowerPC and SystemZ. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181200 91177308-0d34-0410-b5e6-96231b3b80d8
* This exposes more MCJIT options via the C API:Filip Pizlo2013-05-01
| | | | | | | | | | | | | | | | | | | | | | | CodeModel: It's now possible to create an MCJIT instance with any CodeModel you like. Previously it was only possible to create an MCJIT that used CodeModel::JITDefault. EnableFastISel: It's now possible to turn on the fast instruction selector. The CodeModel option required some trickery. The problem is that previously, we were ensuring future binary compatibility in the MCJITCompilerOptions by mandating that the user bzero's the options struct and passes the sizeof() that he saw; the bindings then bzero the remaining bits. This works great but assumes that the bitwise zero equivalent of any field is a sensible default value. But this is not the case for LLVMCodeModel, or its internal equivalent, llvm::CodeModel::Model. In both of those, the default for a JIT is CodeModel::JITDefault (or LLVMCodeModelJITDefault), which is not bitwise zero. Hence this change introduces LLVMInitializeMCJITCompilerOptions(), which will initialize the user's options struct with defaults. The user will use this in the same way that they would have previously used memset() or bzero(). MCJITCAPITest.cpp illustrates the change, as does the comment in ExecutionEngine.h. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180893 91177308-0d34-0410-b5e6-96231b3b80d8

* Introduce llvm::sys::getProcessTriple() function.Peter Collingbourne2013-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | In r143502, we renamed getHostTriple() to getDefaultTargetTriple() as part of work to allow the user to supply a different default target triple at configure time. This change also affected the JIT. However, it is inappropriate to use the default target triple in the JIT in most circumstances because this will not necessarily match the current architecture used by the process, leading to illegal instruction and other such errors at run time. Introduce the getProcessTriple() function for use in the JIT and its clients, and cause the JIT to use it. On architectures with a single bitness, the host and process triples are identical. On other architectures, the host triple represents the architecture of the host CPU, while the process triple represents the architecture used by the host CPU to interpret machine code within the current process. For example, when executing 32-bit code on a 64-bit Linux machine, the host triple may be 'x86_64-unknown-linux-gnu', while the process triple may be 'i386-unknown-linux-gnu'. This fixes JIT for the 32-on-64-bit (and vice versa) build on non-Apple platforms.

* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-02
| | | | | | | | | | | | | | | | | | | | | into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project.
