* [codeview] Use one byte for S_FRAMECOOKIE CookieKind and add flags byteReid Kleckner2016-06-245-5/+7
| | | | | | | | | | We bailed out while printing codeview for an MSVC compiled SemaExprCXX.cpp that used this record. The MS reference headers look incorrect here, which is probably why we had this bug. They use a 32-bit enum as the field type, but the actual record appears to use one byte for the cookie kind followed by a flags byte. llvm-svn: 273691

* [codeview] Emit base class information from DW_TAG_inheritance nodesReid Kleckner2016-06-244-25/+391
| | | | | | | | | | | | | | | | There are two remaining issues here: 1. No vbptr information 2. Need to mention indirect virtual bases Getting indirect virtual bases is just a matter of adding an "indirect" flag, emitting them in the frontend, and ignoring them when appropriate for DWARF. All virtual bases use the same artificial vbptr field, so I think the vbptr offset will be best represented by an implicit __vbptr$ClassName member similar to our existing __vptr$ member. llvm-svn: 273688
* [LV] Preserve order of dependences in interleaved accesses analysisMatthew Simpson2016-06-242-54/+510
| | | | | | | | | | | | | | | | | | | | | | | | | | The interleaved access analysis currently assumes that the inserted run-time pointer aliasing checks ensure the absence of dependences that would prevent its instruction reordering. However, this is not the case. Issues can arise from how code generation is performed for interleaved groups. For a load group, all loads in the group are essentially moved to the location of the first load in program order, and for a store group, all stores in the group are moved to the location of the last store. For groups having members involved in a dependence relation with any other instruction in the loop, this reordering can violate the dependence. This patch teaches the interleaved access analysis how to avoid breaking such dependences, and should fix PR27626. An assumption of the original analysis was that the accesses had been collected in "program order". The analysis was then simplified by visiting the accesses bottom-up. However, this ordering was never guaranteed for anything other than single basic block loops. Thus, this patch also enforces the desired ordering.

* Remangle intrinsics names when types are renamedArtur Pilipenko2016-06-248-2/+169
| | | | | | | | | | | | | This is a resubmittion of previously reverted rL273568.

* ExecutionEngine: silence unused value warningSaleem Abdulrasool2016-06-241-0/+3

* ExecutionEngine: add preliminary support for COFF ARMSaleem Abdulrasool2016-06-243-5/+401
| | | | | | | | | This adds rudimentary support for COFF ARM to the dynamic loader for the exeuction engine. This can be used by lldb to JIT code into a COFF ARM environment. This lays the foundation for the loader, though a few of the relocation types are yet unhandled. llvm-svn: 273682

* [LICM] Avoid repeating expensive call while promoting loads. NFCAnna Thomas2016-06-241-3/+4
| | | | | | | | | | | | | | | Summary: We can avoid repeating the check `isGuaranteedToExecute` when it's already called once while checking if the alignment can be widened for the load/store being hoisted. The function is invariant for the same instruction `UI` in `isGuaranteedToExecute(*UI, DT, CurLoop, SafetyInfo);` Reviewers: hfinkel, eli.friedman Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D21672 llvm-svn: 273671

* [ELF] - Fix incorrect logic in VersionScriptParser::parseVersion()George Rimar2016-06-242-2/+2
| | | | | | | | | | | | | | | | Previously the next sample script would generate 2 entries in Config->SymbolVersions with the same version name. VERSION { global: c; }; That happened because parseVersionSymbols() was called twice. At first for "global:" and since there is no local tag, it was called again. Patch fixes the issue, testcase was updated to demonstrate. Differential revision: http://reviews.llvm.org/D21640 llvm-svn: 273663
