* Add a setLastModificationAndAccessTime to PathV2.Rafael Espindola2013-06-20
| | | | | | With this we can remove the last use of PathV1 from llvm-ar.cpp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184464 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove the simplify-libcalls pass (finally)Meador Inge2013-06-20
| | | | | | | | | | | This commit completely removes what is left of the simplify-libcalls pass. All of the functionality has now been migrated to the instcombine and functionattrs passes. The following C API functions are now NOPs: 1. LLVMAddSimplifyLibCallsPass 2.

* DebugInfo: PR14763/r183329 correct the location of indirect parametersDavid Blaikie2013-06-19
| | | | | | | | | | | | | | | | We had been papering over a problem with location info for non-trivial types passed by value by emitting their type as references (this caused the debugger to interpret the location information correctly, but broke the type of the function). r183329 corrected the type information but lead to the debugger interpreting the pointer parameter as the value - the debug info describing the location needed an extra dereference. Use a new flag in DIVariable to add the extra indirection (either by promoting an existing DW_OP_reg (parameter passed in a register) to DW_OP_breg + 0 or by adding DW_OP_deref to an existing DW_OP_breg + n (parameter passed on the stack). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184368 91177308-0d34-0410-b5e6-96231b3b80d8
* DebugInfo: Specify that a value is stored indirectlyDavid Blaikie2013-06-19
| | | | | | | | | This is a precursor to fix a regression caused by PR14763/r183329 where the location of a non-trivial pass-by-value parameter ends up incorrectly referring directly to the parameter (a pointer) rather than the object pointed to by the pointer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184365 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-dwarfdump: Add support for dumping the .debug_loc sectionDavid Blaikie2013-06-19
| | | | | | | | | This is a basic implementation - we still don't have any support (that I know of) for dumping DWARF expressions in a meaningful way, so the location information itself is just printed as a sequence of bytes as we do elsewhere. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184361 91177308-0d34-0410-b5e6-96231b3b80d8

* [MC/DWARF] Generate multiple .debug_line entries for adjacent .loc directivesUlrich Weigand2013-06-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | The compiler occasionally generates multiple .loc directives in a row (at the same instruction address). These need to be transformed into multple actual .debug_line table entries, since they are used to signal certain information to the debugger (e.g. if the opening brace of a function body is on the same line as the declaration). The MCAsmStreamer version of EmitDwarfLocDirective handles this correctly by emitting a .loc directive every time it is called. However, the MCObjectStream version simply defaults to recording the information and emitting only a single table entry later, e.g. when EmitInstruction is called. This patch introduces a MCAsmStreamer::EmitDwarfLocDirective version that emits a line table entry for a .loc directive that may already be pending before recording the new directive. (This is similar to how this is handled in GNU as.) With this patch (and the code alignment factor patch) applied, I'm now getting identical DWARF .debug sections for all test-suite object files on PowerPC for the internal and the external assembler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184357 91177308-0d34-0410-b5e6-96231b3b80d8

* [APFloat] Added isFiniteNonZero predicate.Michael Gottesman2013-06-19
| | | | | | | | | | | | | | | | | This is the first patch in a series of patches to rename isNormal => isFiniteNonZero and isIEEENormal => isNormal. In order to prevent careless errors on my part the overall plan is: 1. Add the isFiniteNonZero predicate with tests. I can do this in a method independent of isNormal. (This step is this patch). 2. Convert all references to isNormal with isFiniteNonZero. My plan is to comment out isNormal locally and continually convert isNormal references => isFiniteNonZero until llvm/clang compiles. 3. Remove old isNormal and rename isIEEENormal to isNormal. 4. Look through all of said references from patch 2 and see if we can simplify them by using the new isNormal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184350 91177308-0d34-0410-b5e6-96231b3b80d8

* Switch spill weights from a basic loop depth estimation to BlockFrequencyInfo.Benjamin Kramer2013-06-17
| | | | | | | | | | | | | | | | | | The main advantages here are way better heuristics, taking into account not just loop depth but also __builtin_expect and other static heuristics and will eventually learn how to use profile info. Most of the work in this patch is pushing the MachineBlockFrequencyInfo analysis into the right places. This is good for a 5% speedup on zlib's deflate (x86_64), there were some very unfortunate spilling decisions in its hottest loop in longest_match(). Other benchmarks I tried were mostly neutral. This changes register allocation in subtle ways, update the tests for it. 2012-02-20-MachineCPBug.ll was deleted as it's very fragile and the instruction it looked for was gone already (but the FileCheck pattern picked up unrelated stuff). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184105 91177308-0d34-0410-b5e6-96231b3b80d8
