* IEEE-754R 5.7.2 General Operations is* operations (except for isCanonical).Michael Gottesman2013-06-041-0/+61
| | | | | | | | | | | | | | | Specifically the following work was done: 1. If the operation was not implemented, I implemented it. 2. If the operation was already implemented, I just moved its location in the APFloat header into the IEEE-754R 5.7.2 section. If the name was incorrect, I put in a comment giving the true IEEE-754R name. Also unittests have been added for all of the functions which did not already have a unittest. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183179 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | 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

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 Blaikie2013-05-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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 Pizlo2013-05-141-2/+2
| | | | | | | | | | | | | | | | | | | 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

* [SystemZ] Set up JIT/MCJIT test casesUlrich Weigand2013-05-063-6/+9
| | | | | | | | | | | | | 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 Weigand2013-05-062-28/+10
| | | | | | | | | | | | | | | | | | | | | 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

* PatternMatch: Matcher for (un)ordered floating point min/maxArnold Schwaighofer2013-05-051-0/+265
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for matching 'ordered' and 'unordered' floating point min/max constructs. In LLVM we can express min/max functions as a combination of compare and select. We have support for matching such constructs for integers but not for floating point. In floating point math there is no total order because of the presence of 'NaN'. Therefore, we have to be careful to preserve the original fcmp semantics when interpreting floating point compare select combinations as a minimum or maximum function. The resulting 'ordered/unordered' floating point maximum function has to select the same value as the select/fcmp combination it is based on. ordered_max(x,y) = max(x,y) iff x and y are not NaN, y otherwise unordered_max(x,y) = max(x,y) iff x and y are not NaN, x otherwise ordered_min(x,y) = min(x,y) iff x and y are not NaN, y otherwise unordered_min(x,y) = min(x,y) iff x and y are not NaN, x otherwise This matches the behavior of the underlying select(fcmp(olt/ult/.., L, R), L, R) construct. Any code using this predicate has to preserve this semantics. A follow-up patch will use this to implement floating point min/max reductions in the vectorizer. radar://13723044 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181143 91177308-0d34-0410-b5e6-96231b3b80d8
* This exposes more MCJIT options via the C API:Filip Pizlo2013-05-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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
