* Revert "[InstCombine] re-commit r218721 with fix for pr21199"Justin Bogner2014-10-086-300/+9
| | | | | | | | | | | | | This seems to cause a miscompile when building clang, which causes a bootstrapped clang to fail or crash in several of its tests. See: http://lab.llvm.org:8013/builders/clang-x86_64-darwin11-RA/builds/1184 http://bb.pgr.jp/builders/clang-3stage-x86_64-linux/builds/7813 This reverts commit r219282. llvm-svn: 219317

* Remove bogus std::error_code returns form SectionRef.Rafael Espindola2014-10-0822-470/+252
| | | | | | | | | | | | | | There are two methods in SectionRef that can fail: * getName: The index into the string table can be invalid. * getContents: The section might point to invalid contents. Every other method will always succeed and returning and std::error_code just complicates the code. For example, a section can have an invalid alignment, but if we are able to get to the section structure at all and create a SectionRef, we will always be able to read that invalid alignment. llvm-svn: 219314

* Update dwarf::ApplePropertyAttributes enum to meaningful values.Frederic Riss2014-10-082-19/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: We currently emit an DW_AT_APPLE_property_attribute with a value that is a bitfield describing the various attributes applied to an ObjectiveC property. While trying to add testing to one of my dwarfdump patches that would pretty print that, I realized this information looks totally broken and has maybe never been correct. As with every DWARF info, we have some enum in Dwarf.h that describes this attribute (enum ApplePropertyAttributes). It seems however that the attribute value is set from another definition of these flags in Sema/DeclSpec.h (enum ObjCPropertyAttributeKind). And these 2 enums aren't in sync. This patch updates the Dwarf.h values to the ones we are (and have been for a very long time) emitting. We change some publicly (and even documented in SourceLevelDebugging.rst) values, but I doubt this could be an issue as the information has been wrong for so long...

* [AVX512] Refactoring of avx512_binop_rm multiclass through AVX512_masking.Robert Khasanov2014-10-082-133/+60
| | | | | | | Added new argrument for AVX512_masking: InstrItinClass and bit isCommutable. No functional change. llvm-svn: 219310
* Remove an out of date comment.Rafael Espindola2014-10-081-1/+0
| | | | | | | After 4 years there is still no normalization library. We do support disassembly and relocations, so it doesn't look like we need it. llvm-svn: 219308

* Refactor isThumb1Only() && isMClass() into a predicate called isV6M()Renato Golin2014-10-082-5/+8
| | | | | | | | | This must be enforced for all v6M cores, not just the cortex-m0, irregardless of the user-specified alignment. Patch by Charlie Turner. llvm-svn: 219300
* Simplify switch statement in ARM subtarget align accessRenato Golin2014-10-081-30/+24
| | | | | | | | This switch can be reduced to a simpler if/else statement. Patch by Charlie Turner. llvm-svn: 219299

* Update git-svnrevert to accept git and svn revisionsRenato Golin2014-10-081-9/+16
| | | | | | | | | | Interchangeable commit ids can now be used on this git-svnrevert, which will figure out what kind of commit that is (if you use format rNNNN for SVN commits) and make sure the right ids are used in the right places. It's a little bit more robust and user-friendly. llvm-svn: 219290
* Unix/Process: Don't use pthread_sigmask if we aren't built with threadsDavid Majnemer2014-10-081-1/+12
| | | | | | | | We won't link in pthreads if we weren't built with LLVM_ENABLE_THREADS which means we won't get access to pthread_sigmask. Use sigprocmask instead. llvm-svn: 219288

* GlobalOpt: Don't drop unused memberes of a ComdatDavid Majnemer2014-10-082-8/+39
| | | | | | | | | A linkonce_odr member of a COMDAT shouldn't be dropped if we need to keep the entire COMDAT group. This fixes PR21191. llvm-svn: 219283
* [InstCombine] re-commit r218721 with fix for pr21199Gerolf Hoflehner2014-10-086-9/+300
| | | | | | | | The icmp-select-icmp optimization targets select-icmp.eq only. This is now ensured by testing the branch predicate explictly. This commit also includes the test case for pr21199. llvm-svn: 219282
* COFF: Don't oversize COMMON symbols when targeting BFD ldDavid Majnemer2014-10-082-6/+12
| | | | | | | | | | | | | | COFF normally doesn't allow us to describe the alignment of COMMON symbols. It turns out that most linkers use the symbol size as a hint as to how aligned the symbol should be. However the BFD folks have added a .drectve command, which we now support as of r219229, that allows us to specify the alignment precisely. With this in mind, stop rounding sizes up. llvm-svn: 219281
* llvm-dwarfdump: Add support for some COFF relocationsDavid Majnemer2014-10-084-36/+87
| | | | | | | DWARF in COFF utilizes several relocations. Implement support for them in RelocVisitor to support llvm-dwarfdump. llvm-svn: 219280

* [DebugInfo] Pass DWARFSection down to DWARFUnit constructor (NFC).Alexey Samsonov2014-10-084-25/+25
| | | | | | Keep the actual section contents and the relocation map together. llvm-svn: 219261
* [Support] Add MemoryBuffer::getFileSlice()Nick Kledzik2014-10-083-8/+69
| | | | | | | | | | mach-o supports "fat" files which are a header/table-of-contents followed by a concatenation of mach-o files built for different architectures. Currently, MemoryBuffer has no easy way to map a subrange (slice) of a file which lld will need to select a mach-o slice of a fat file. The new function provides an easy way to map a slice of a file into a MemoryBuffer. Test case included. llvm-svn: 219260

* [X86] Fix a bug with fetch_add(INT32_MIN)Robin Morisset2014-10-072-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Fix pr21099 The pseudocode of what we were doing (spread through two functions) was: if (operand.doesNotFitIn32Bits()) Opc.initializeWithFoo(); if (operand < 0) operand = -operand; if (operand.doesFitIn8Bits()) Opc.initializeWithBar(); else if (operand.doesFitIn32Bits()) Opc.initializeWithBlah(); doStuff(Opc); So for operand == INT32_MIN, Opc was never initialized because the operand changes from fitting in 32 bits to not fitting, causing the various bugs/error messages noted by pr21099. This patch adds an extra test at the beginning for this case, and an llvm_unreachable to have better error message if the operand ends up not fitting in 32-bits at the end.

* DebugInfo+DFSan: Ensure that debug info references to llvm::Functions remain ↵David Blaikie2014-10-073-0/+48
| | | | | | | | | | | | | | | | | | | | | | pointing to the underlying function when wrappers are created This is somewhat the inverse of how similar bugs in DAE and ArgPromo manifested and were addressed. In those passes, individual call sites were visited explicitly, and then the old function was deleted. This left the debug info with a null llvm::Function* that needed to be updated to point to the new function. In the case of DFSan, it RAUWs the old function with the wrapper, which includes debug info. So now the debug info refers to the wrapper, which doesn't actually have any instructions with debug info in it, so it is ignored entirely - resulting in a DW_TAG_subprogram with no high/low pc, etc. Instead, fix up the debug info to refer to the original function after the RAUW messed it up. Reviewed/discussed with Peter Collingbourne on the llvm-dev mailing list. llvm-svn: 219249
* [Bugpoint] Close error log in ProcessFailure. Bugpoint had been failing to closeLang Hames2014-10-071-9/+1
| | | | | | | | | | this, and in some circumstances (e.g. reducing particularly large test-cases) this was causing bugpoint to be killed for hitting open file-handle limits. No test case: I was only able to trigger this with test cases taking upwards of 10 mins to run. llvm-svn: 219244

* LoopUnroll: Create sub-loops in LoopInfoDuncan P. N. Exon Smith2014-10-072-1/+64
| | | | | | | | | | | | | `LoopUnrollPass` says that it preserves `LoopInfo` -- make it so. In particular, tell `LoopInfo` about copies of inner loops when unrolling the outer loop. Conservatively, also tell `ScalarEvolution` to forget about the original versions of these loops, since their inputs may have changed. Fixes PR20987. llvm-svn: 219241

* R600: Use MCAsmInfoELF as AMDGPUMCAsmInfo base classTom Stellard2014-10-072-3/+8
| | | | | | | | | | | | | The main reason for this is that the MCAsmInfo class, which we were previously using as the base class, sets PrivateGlobalPrefix to "L", which causes all global functions that start with L to be treated as local symbols. MCAsmInfoELF sets PrivateGlobalPrefix to ".L", which is what we want, and it is probably a good idea to use this as the base class anyway, since we are emitting ELF binaries. llvm-svn: 219237
