* R600: Implement TargetLowering::getVectorIdxTy()Tom Stellard2013-08-053-5/+14
| | | | | | | We use MVT::i32 for the vector index type, because we use 32-bit operations to caculate offsets when dynamically indexing vectors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187749 91177308-0d34-0410-b5e6-96231b3b80d8
* TargetLowering: Add getVectorIdxTy() function v2Tom Stellard2013-08-059-77/+105
| | | | | | | | | | | | | | | | | | | | | This virtual function can be implemented by targets to specify the type to use for the index operand of INSERT_VECTOR_ELT, EXTRACT_VECTOR_ELT, INSERT_SUBVECTOR, EXTRACT_SUBVECTOR. The default implementation returns the result from TargetLowering::getPointerTy() The previous code was using TargetLowering::getPointerTy() for vector indices, because this is guaranteed to be legal on all targets. However, using TargetLowering::getPointerTy() can be a problem for targets with pointer sizes that differ across address spaces. On such targets, when vectors need to be loaded or stored to an address space other than the default 'zero' address space (which is the address space assumed by TargetLowering::getPointerTy()), having an index that is a different size than the pointer can lead to inefficient pointer calculations, (e.g. 64-bit adds for a 32-bit address space). There is no intended functionality change with this patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187748 91177308-0d34-0410-b5e6-96231b3b80d8

* Introduce an optimisation for special case lists with large numbers of ↵Peter Collingbourne2013-08-052-14/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | literal entries. Our internal regex implementation does not cope with large numbers of anchors very efficiently. Given a ~3600-entry special case list, regex compilation can take on the order of seconds. This patch solves the problem for the special case of patterns matching literal global names (i.e. patterns with no regex metacharacters). Rather than forming regexes from literal global name patterns, add them to a StringSet which is checked before matching against the regex. This reduces regex compilation time by an order of roughly thousands when reading the aforementioned special case list, according to a completely unscientific study. No test cases. I figure that any new tests for this code should check that regex metacharacters are properly recognised. However, I could not find any documentation which documents the fact that the syntax of global names in special case lists is based on regexes. The extent to which regex syntax is supported in special case lists should probably be decided on/documented before writing tests.

* [SystemZ] Use BRCT and BRCTG to eliminate add-&-compare sequencesRichard Sandiford2013-08-058-18/+419
| | | | | | | | | | | | | | | | | This patch just uses a peephole test for "add; compare; branch" sequences within a single block. The IR optimizers already convert loops to decrement-and-branch-on-nonzero form in some cases, so even this simplistic test triggers many times during a clang bootstrap and projects/test-suite run. It looks like there are still cases where we need to more strongly prefer branches on nonzero though. E.g. I saw a case where a loop that started out with a check for 0 ended up with a check for -1. I'll try to look at that sometime. I ended up adding the Reference class because MachineInstr::readsRegister() doesn't check for subregisters (by design, as far as I could tell). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187723 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix PPC64 64-bit GPR inline asm constraint matchingHal Finkel2013-08-032-1/+83
| | | | | | | | | | | | | | | Internally, the PowerPC backend names the 32-bit GPRs R[0-9]+, and names the 64-bit parent GPRs X[0-9]+. When matching inline assembly constraints with explicit register names, on PPC64 when an i64 MVT has been requested, we need to follow gcc's convention of using r[0-9]+ to refer to the 64-bit (parent) registers. At some point, we'll probably want to arrange things so that the generic code in TargetLowering uses the AsmName fields declared in *RegisterInfo.td in order to match these inline asm register constraints. If we do that, this change can be reverted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187693 91177308-0d34-0410-b5e6-96231b3b80d8

* Link with -rdynamic instead of -Wl,-export-dynamic.Bob Wilson2013-08-026-14/+16
| | | | | | | | | | | | | | | Recent versions of the OS X linker support this but follow the existing OS X linker convention of using an underscore in the option name, i.e., -export_dynamic. Rather than changing our configure scripts to check for that alternate spelling, it is simpler to just use the compiler's -rdynamic option and let it deal with translating that to the appropriate linker option. One potential disadvantage of this approach is that the compiler will typically ignore -rdynamic on platforms where it is not supported, so the HAVE_LINK_EXPORT_DYNAMIC in config.h will not necessarily show whether that option has any effect or not. I don't see any in-tree uses of that macro, so I'm assuming it is OK. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187686 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix invalid function pointers in bugpoint ExtractLoopsHal Finkel2013-08-021-7/+42
| | | | | | | | | | | | | | | | | | | | | | | The ExtractLoops function tries to reduce the failing test case by extracting one or more loops from the misoptimized piece of the program. In doing this, ExtractLoops must keep the MiscompiledFunctions vector up-to-date by ensuring that the pointers refer to functions in the current failing program. Unfortunately, this is not trivial because: - ExtractLoops is iterative, and there are several early exits (and the MiscompiledFunctions vector must be consistent with the current program at every non-fatal exit point). - Several of the utility functions used by ExtractLoops (such as TestOptimizer, some of which are called through the TestFn callback parameter, and Linker::LinkModules) delete their inputs upon success. This change adds several updates of the MiscompiledFunctions vector at different points. The first is after the initial call to TestMergedProgram which checks that the loop-extracted program still works. The second is after the call to TestFn (TestOptimizer, for example). This function will delete its inputs (which is why the existing ExtractLoops logic cloned the inputs first). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187674 91177308-0d34-0410-b5e6-96231b3b80d8
