* [x86] Combine x86mmx/i64 to v2i64 conversion to use scalar_to_vectorBruno Cardoso Lopes2015-01-231-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Handle the poor codegen for i64/x86xmm->v2i64 (%mm -> %xmm) moves. Instead of using stack store/load pair to do the job, use scalar_to_vector directly, which in the MMX case can use movq2dq. This was the current behavior prior to improvements for vector legalization of extloads in r213897. This commit fixes the regression and as a side-effect also remove some unnecessary shuffles. In the new attached testcase, we go from: pshufw $-18, (%rdi), %mm0 movq %mm0, -8(%rsp) movq -8(%rsp), %xmm0 pshufd $-44, %xmm0, %xmm0 movd %xmm0, %eax ... To: pshufw $-18, (%rdi), %mm0 movq2dq %mm0, %xmm0 movd %xmm0, %eax ... Differential Revision: http://reviews.llvm.org/D7126 rdar://problem/19413324 llvm-svn: 226953

* R600/SI: Move i64 -> v2i32 load promotion into AMDGPUDAGToDAGISel::Select()Tom Stellard2015-01-232-3/+22
| | | | | | | | | | | We used to do this promotion during DAG legalization, but this caused an infinite loop in ExpandUnalignedLoad() because it assumed that i64 loads were legal if i64 was a legal type. It also seems better to report i64 loads as legal, since they actually are and we were just promoting them to simplify our tablegen files. llvm-svn: 226945

* [Orc] New JIT APIs.Lang Hames2015-01-2314-8/+886
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new set of JIT APIs to LLVM. The aim of these new APIs is to cleanly support a wider range of JIT use cases in LLVM, and encourage the development and contribution of re-usable infrastructure for LLVM JIT use-cases. These APIs are intended to live alongside the MCJIT APIs, and should not affect existing clients. Included in this patch: 1) New headers in include/llvm/ExecutionEngine/Orc that provide a set of components for building JIT infrastructure. Implementation code for these headers lives in lib/ExecutionEngine/Orc. 2) A prototype re-implementation of MCJIT (OrcMCJITReplacement) built out of the new components. 3) Minor changes to RTDyldMemoryManager needed to support the new components. These changes should not impact existing clients. 4) A new flag for lli, -use-orcmcjit, which will cause lli to use the OrcMCJITReplacement class as its underlying execution engine, rather than MCJIT itself. Tests to follow shortly. Special thanks to Michael Ilseman, Pete Cooper, David Blaikie, Eric Christopher, Justin Bogner, and Jim Grosbach for extensive feedback and discussion. llvm-svn: 226940

* LowerSwitch: replace unreachable default with popular case destinationHans Wennborg2015-01-231-63/+135
| | | | | | | | | | | | SimplifyCFG currently does this transformation, but I'm planning to remove that to allow other passes, such as this one, to exploit the unreachable default. This patch takes care to keep track of what case values are unreachable even after the transformation, allowing for more efficient lowering.

* Classify functions by EH personality type rather than using the tripleReid Kleckner2015-01-238-17/+32
| | | | | | | | | | | | | | | This mostly reverts commit r222062 and replaces it with a new enum. At some point this enum will grow at least for other MSVC EH personalities. Also beefs up the way we were sniffing the personality function. Previously we would emit the Itanium LSDA despite using __C_specific_handler.

Summary: We used to silently ignore any empty .module's and we used to give an error saying that we found an "unexpected token at start of statement" when the value of the option wasn't an identifier (e.g. if it was a number). We now give an error saying that we "expected .module option identifier" in both of those cases. I also fixed the other tests in mips-abi-bad.s, which all seemed to be broken.

* [PM] Actually add the new pass manager support for the assumption cache.Chandler Carruth2015-01-221-0/+15
| | | | | | | | | | | | | | | I had already factored this analysis specifically to enable doing this, but hadn't actually committed the necessary wiring to get at this from the new pass manager. This also nicely shows how the separate cache object can be directly managed by the new pass manager. This analysis didn't have any direct tests and so I've added a printer pass and a boring test case. I chose to print the i1 value which is being assumed rather than the call to llvm.assume as that seems much more useful for testing... but suggestions on an even better printing strategy welcome. My main goal was to make sure things actually work. =] llvm-svn: 226868

* IR: Update references to temporaries before deletingDuncan P. N. Exon Smith2015-01-221-0/+1
| | | | | | | | | | | | | | | | During `MDNode::deleteTemporary()`, call `replaceAllUsesWith(nullptr)` to update all tracking references to `nullptr`. This fixes PR22280, where inverted destruction order between tracking references and the temporaries themselves caused a use-after-free in `LLParser`. An alternative fix would be to add an assertion that there are no users, and continue to fix inverted destruction order in clients (like `LLParser`), but instead I decided to make getting-teardown-right easy. (If someone disagrees let me know.) llvm-svn: 226866
* Refactoring cl::parser construction and initialization.Chris Bieneman2015-01-221-2/+2
| | | | | | | | | | | | | | | Summary: Some parsers need references back to the option they are members of. This is used for handling the argument string as well as by the various pass name parsers for making pass names into flags. Making parsers that need to refer back to the option have a reference to the option eliminates some of the members of various parsers, and enables further code cleanup.

* merge consecutive stores of extracted vector elements (PR21711)Sanjay Patel2015-01-221-92/+162
| | | | | | | | | | | | | | | | | | This is a 2nd try at the same optimization as http://reviews.llvm.org/D6698. That patch was checked in at r224611, but reverted at r225031 because it caused a failure outside of the regression tests. The cause of the crash was not recognizing consecutive stores that have mixed source values (loads and vector element extracts), so this patch adds a check to bail out if any store value is not coming from a vector element extract. This patch also refactors the shared logic of the constant source and vector extracted elements source cases into a helper function.

* AArch64: decode all MRS/MSR forms early to avoid saving FeatureBits.Tim Northover2015-01-221-42/+35
| | | | | | | | | | | | Currently, we're adding a uint64_t describing the current subtarget so that matching can check whether the specified register is valid. However, we want to move to a bitset for those bits (x86 has more than 64 of them). This can't live in a union so it's probably better to do the checks early (especially as there are only 3 of them). llvm-svn: 226841

* [pr21886] Change MCJIT/ELF to support MSVC C++ mangled symbol.Rafael Espindola2015-01-221-9/+36
| | | | | | | | | | | | The ELF format is used on Windows by the MCJIT engine. Thus, on Windows, the ELFObjectWriter can encounter symbols mangled using the MS Visual Studio C++ name mangling. Symbols mangled using the MSVC C++ name mangling can legally have "@@@" as a substring. The EFLObjectWriter should not interpret the "@@@" substring as specifying GNU-style symbol versioning. The ELFObjectWriter therefore check for the MSVC C++ name mangling prefix which is either "?", "@?", "imp_?" or "imp_?@". llvm-svn: 226830
