* Add support for getting the last modification time from a file_status.Rafael Espindola2013-06-202-0/+17
| | | | | | Use that in llvm-ar.cpp to replace a use of sys::PathWithStatus. llvm-svn: 184450
* Clang-format the SLP vectorizer. No functionality change.Nadav Rotem2013-06-203-202/+259
| | | | llvm-svn: 184446
* This reverts r155000.Joey Gouly2013-06-201-6/+1
| | | | | | | | | The cdp2 instruction should have the same restrictions as cdp on the co-processor registers. VFP instructions on v8/AArch32 share the same encoding space as cdp2. llvm-svn: 184445
* SLPVectorization: Add a basic support for cross-basic block slp vectorization.Nadav Rotem2013-06-203-13/+80
| | | | | | | We collect gather sequences when we vectorize basic blocks. Gather sequences are excellent hints for vectorization of other basic blocks. llvm-svn: 184444
* [PowerPC] Remove unused parameterUlrich Weigand2013-06-203-14/+14
| | | | | | | The isDarwin parameter to the llvm::LowerPPCMachineInstrToMCInst routine is now no longer needed; remove it. llvm-svn: 184441
* Change the debug type to match the debug type that is used by vecutils.cpp.Nadav Rotem2013-06-201-1/+1
| | | | | | This change makes it easier to filter debug messages. llvm-svn: 184440
* [PowerPC] Add missing build dependencyUlrich Weigand2013-06-201-1/+1
| | | | | | | This (hopefully) fixes build failures resulting from r184436; the PowerPC asm parser now depends on PowerPC target expresssions. llvm-svn: 184439
* [MC] Support @ variants with directional labelsUlrich Weigand2013-06-201-2/+12
| | | | | | | | | | | The assembler parser common code supports recognizing symbol variants using the @ modifer. On PowerPC, it should also be possible to use (some of) those modifiers with directional labels, like "1f@l". This patch adds support for accepting symbol variants on directional labels as well. llvm-svn: 184437
* [PowerPC] Optimize @ha/@l constructsUlrich Weigand2013-06-204-46/+144
| | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for having the assembler optimize fixups to constructs like "symbol@ha" or "symbol@l" if "symbol" can be resolved at assembler time. This optimization is already present in the PPCMCExpr.cpp code for handling PPC_HA16/PPC_LO16 target expressions. However, those target expression were used only on Darwin targets. This patch changes target expression code so that they are usable also with the GNU assembler (using the @ha / @l syntax instead of the ha16() / lo16() syntax), and changes the MCInst lowering code to generate those target expressions where appropriate. It also changes the asm parser to generate HA16/LO16 target expressions when parsing assembler source that uses the @ha / @l modifiers. The effect is that now the above- mentioned optimization automatically becomes available for those situations too. llvm-svn: 184436
* [PowerPC] Support compare mnemonics with implied CR0Ulrich Weigand2013-06-201-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Just like for branch mnemonics (where support was recently added), the assembler is supposed to support extended mnemonics for the compare instructions where no condition register is specified explicitly (and CR0 is assumed implicitly). This patch adds support for those extended compare mnemonics.

Fix that bug while I'm here. llvm-svn: 184387
* [Support/CrashRecoveryContext] Make sure CrashRecoveryContext does not clear ↵Argyrios Kyrtzidis2013-06-191-2/+11
| | | | | | | | | | | | | | | | | the thread-local "CurrentContext" in the "parent" thread, when we are using CrashRecoveryContext::RunSafelyOnThread. When using CrashRecoveryContext::RunSafelyOnThread, we would set a CrashRecoveryContextImpl* to a thread-local variable for the "child" thread, but CrashRecoveryContext would erroneously clear it in the "parent" thread. The result was that if CrashRecoveryContext::RunSafelyOnThread was called again in the "child" thread it would mess up crash-recovery for its parent. A test for this will be added in the clang repository. rdar://14204560 llvm-svn: 184380

* DebugInfo: PR14763/r183329 correct the location of indirect parametersDavid Blaikie2013-06-194-11/+16
| | | | | | | | | | | | | | | | 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). llvm-svn: 184368

| | | | | | | | | 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. llvm-svn: 184361

* [MC/DWARF] Generate multiple .debug_line entries for adjacent .loc directivesUlrich Weigand2013-06-191-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 184357
