* [WinEH] Move WinEHFuncInfo from MachineModuleInfo to MachineFunctionReid Kleckner2015-11-1715-193/+120
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Now that there is a one-to-one mapping from MachineFunction to WinEHFuncInfo, we don't need to use a DenseMap to select the right WinEHFuncInfo for the current funclet. The main challenge here is that X86WinEHStatePass is an IR pass that doesn't have access to the MachineFunction. I gave it its own WinEHFuncInfo object that it uses to calculate state numbers, which it then throws away. As long as nobody creates or removes EH pads between this pass and SDAG construction, we will get the same state numbers. The other thing X86WinEHStatePass does is to mark the EH registration node. Instead of communicating which alloca was the registration through WinEHFuncInfo, I added the llvm.x86.seh.ehregnode intrinsic. This intrinsic generates no code and simply marks the alloca in use.

* [EH] Keep filter clauses for types that have been caught.Andrew Kaylor2015-11-172-8/+25
| | | | | | | | The instruction combiner previously removed types from filter clauses in Landing Pad instructions if the type had previously been seen in a catch clause. This is incorrect and prevents unexpected exception handlers from rethrowing the caught type. Differential Revision: http://reviews.llvm.org/D14669 llvm-svn: 253370
* [RuntimeDyld] Fix resolving R_PPC64_REL24 relocationsUlrich Weigand2015-11-171-3/+3
| | | | | | | | | | | | | | | When resolving R_PPC64_REL24, code used to check for an address delta that fits in 24 bits, while the instructions that take this relocation actually can process address deltas that fit into *26* bits (as those instructions have a 24 bit field, but implicitly append two zero bits at the end since all instruction addresses are a multiple of 4). This means that code would signal overflow once a single object's text section exceeds 8 MB, while we can actually support up to 32 MB. Partially fixes PR25540. llvm-svn: 253369

* Switch lto codegen to using diagnostic handlers.Yunzhong Gao2015-11-174-53/+68
| | | | | | | | | | | This patch removes the std::string& argument from a number of C++ LTO API calls and instead makes them use the installed diagnostic handler. This would also improve consistency of diagnostic handling infrastructure: if an LTO client used lto_codegen_set_diagnostic_handler() to install a custom error handler, we do not want some error messages to go through the custom error handler, and some other error messages to go into sLastErrorString. llvm-svn: 253367

* Vector of pointers in function attributes calculationElena Demikhovsky2015-11-172-1/+39

| | | | | | | | | | | | The tzcnt intrinsics are used non non-BMI targets by code (e.g. ffmpeg) that uses it as a potentially faster BSF. The TZCNT instruction is special in that it's encoded in a backward-compatible way and behaves as BSF on non-BMI targets. Differential Revision: http://reviews.llvm.org/D14748 llvm-svn: 253358

* ARM: fix mismatch between Clang and backend on exception type.Tim Northover2015-11-172-7/+11
| | | | | | | | | | | | "-arch armv7k" is only normally used with a watchos target, but Clang doesn't stop you from giving a "-miphoneos-version-min" option too, converting the triple to "thumbv7k-apple-ios". In this case the backend will decide to use SjLj exceptions, so Clang needs to agree so it can create the correct predefines. Fortunately, there's a handy function to make the decision for us now. llvm-svn: 253355

* [ARM] Don't pessimize i32 vselect.Charlie Turner2015-11-173-11/+9
| | | | | | | | | | | | | | | | | | The underlying issues surrounding codegen for 32-bit vselects have been resolved. The pessimistic costs for 64-bit vselects remain due to the bad scalarization that is still happening there. I tested this on A57 in T32, A32 and A64 modes. I saw no regressions, and some improvements. From my benchmarks, I saw these improvements in A57 (T32) spec.cpu2000.ref.177_mesa 5.95% lnt.SingleSource/Benchmarks/Shootout/strcat 12.93% lnt.MultiSource/Benchmarks/MiBench/telecomm-CRC32/telecomm-CRC32 11.89% I also measured A57 A32, A53 T32 and A9 T32 and found no performance regressions.

* [Support] Tweak path::system_temp_directory() on Windows.Pawel Bylica2015-11-172-16/+85
| | | | | | | | | | | | | | | | | Summary: This patch changes the behavior of path::system_temp_directory() on Windows to be closer to GetTempPath Windows API call. Enforces path separator to be the native one, makes path absolute, etc. GetTempPath is not used directly because of limitations/implementation bugs on Windows 7. Windows specific unit tests are added. Most of them runs in separated process with modified environment variables. This change fixes FileSystemTest.CreateDir unittest that had been failing when run from Unix-like shell on Windows (Unix-like path separator (/) used in env variables).

* [AArch64] Promote f16 SELECT_CC CC operands when op is legal.Ahmed Bougacha2015-11-172-1/+34
| | | | | | | | | | | | | | | | SELECT_CC has the nasty property of having operands with unrelated types. So if you do something like: f32 = select_cc f16, f16, f32, f32, cc You'd only look for the action for <select_cc, f32>, but never f16. If the types are all legal, but the op isn't (as for f16 on AArch64, or for f128 on x86_64/AArch64?), then you get into trouble. For f128, we have softenSetCCOperands to handle this case. Similarly, for f16, we can directly promote the CC operands. llvm-svn: 253344
* [llvm-rtdyld] Don't waste cycles invalidating instruction cache.Davide Italiano2015-11-171-20/+4
| | | | | | | | | | | | | Now that setExecutable() changed to do all the ground work to make memory executable on the host, we can remove all (redundant) calls to invalidate instruction cache here. As an added bonus, this makes invalidateInstructionCache() dead code, so it can be removed. Differential Revision: http://reviews.llvm.org/D13631 llvm-svn: 253343

* Lower statepoints with multi-def targets.Pat Gavlin2015-11-172-8/+30
| | | | | | | | | | Statepoint lowering currently expects that the target method of a statepoint only defines a single value. This precludes using statepoints with ABIs that return values in multiple registers (e.g. the SysV AMD64 ABI). This change adds support for lowering statepoints with mutli-def targets. llvm-svn: 253339
* Use TargetRegisterInfo for printing MachineOperand register commentsDan Gohman2015-11-179-17/+25
| | | | | | | | | | | | | | | | Several places in AsmPrinter.cpp print comments describing MachineOperand registers using MCRegisterInfo, which uses MCOperand-oriented names. This doesn't work for targets that use virtual registers exclusively, as WebAssembly does, since virtual registers are represented and printed differently. This patch preserves what seems to be the spirit of r229978, avoiding the use of TM.getSubtargetImpl(), while still using MachineOperand-oriented printing for MachineOperands.

* ScopInfo: Ensure unique names for parameter names coming from load instructionsTobias Grosser2015-11-172-8/+16
| | | | | | | | | | | | | | | | In case the original parameter instruction does not have a name, but it comes from a load instruction where the base pointer has a name we used the name of the load instruction to give some more intuition of where the parameter came from. To ensure this works also through GEPs which may have complex offsets, we originally just dropped the offsets and _only_ used the base pointer name. As this can result in multiple parameters to get the same name, we now prefix the parameter ID to ensure parameter names are unique. This will make it easier to understand debug output. This change does not affect correctness, as parameter IDs (even of the same name) can always be distinguished through the SCEV pointer stored inside them. llvm-svn: 253330

* [Assembler] Make fatal assembler errors non-fatalOliver Stannard2015-11-1741-215/+419
| | | | | | | | | | | | | | Currently, if the assembler encounters an error after parsing (such as an out-of-range fixup), it reports this as a fatal error, and so stops after the first error. However, for most of these there is an obvious way to recover after emitting the error, such as emitting the fixup with a value of zero. This means that we can report on all of the errors in a file, not just the first one. MCContext::reportError records the fact that an error was encountered, so we won't actually emit an object file with the incorrect contents. Differential Revision: http://reviews.llvm.org/D14717 llvm-svn: 253328
* [Assembler] Allow non-fatal errors after parsingOliver Stannard2015-11-175-9/+25
| | | | | | | | | | | | | | | | | This adds reportError to MCContext, which can be used as an alternative to reportFatalError when the assembler wants to try to continue processing the rest of the file after the error is reported, so that all of the errors ina file can be reported. It records the fact that an error was encountered, so we can avoid emitting an object file if any errors occurred. This patch doesn't add any uses of this function (a later patch will convert most uses of reportFatalError to use it), but there is a small functional change: we use the SourceManager to print the error message, even if we have a null SMLoc. This means that we get a SourceManager-style message, with the file and line information shown as <unknown>, rather than the "LLVM ERROR" style used by report_fatal_error. llvm-svn: 253327
