* [WebAssembly] Remove an unused data member. NFC.Dan Gohman2016-01-193-10/+7

* Fix undefined behavior in llvm's local changes to googletest.Nico Weber2016-01-192-1/+5
| | | | | | | | | r100895 landed an llvm-only change to add minix support to googletest. It did that by putting "defined()" in a macro, which has undefined behavior. Slightly reshuffle things to remove that undefined behavior. Also mention in README.LLVM that minix support is a local change. llvm-svn: 258190

* [Orc] Refactor ObjectLinkingLayer::addObjectSet to defer loading objects untilLang Hames2016-01-195-107/+278
| | | | | | | | | | | | | | | | they're needed. Prior to this patch objects were loaded (via RuntimeDyld::loadObject) when they were added to the ObjectLinkingLayer, but were not relocated and finalized until a symbol address was requested. In the interim, another object could be loaded and finalized with the same memory manager, causing relocation/finalization of the first object to fail (as the first finalization call may have marked the allocated memory for the first object read-only). By deferring the loadObject call (and subsequent memory allocations) until an object file is needed we can avoid prematurely finalizing memory. llvm-svn: 258185
* [SCEV] Fix PR26207Sanjoy Das2016-01-193-1/+33
| | | | | | | | | | | | | | | | | | | | | | | In some cases, the max backedge taken count can be more conservative than the exact backedge taken count (for instance, because ScalarEvolution::getRange is not control-flow sensitive whereas computeExitLimitFromICmp can be). In these cases, computeExitLimitFromCond (specifically the bit that deals with `and` and `or` instructions) can create an ExitLimit instance with a `SCEVCouldNotCompute` max backedge count expression, but a computable exact backedge count expression. This violates an implicit SCEV assumption: a computable exact BE count should imply a computable max BE count. This change - Makes the above implicit invariant explicit by adding an assert to ExitLimit's constructor - Changes `computeExitLimitFromCond` to be more robust around conservative max backedge counts llvm-svn: 258184

* [OpenMP] Detect implicit map type to report unspecified map type for target ↵Samuel Antao2016-01-198-44/+76
| | | | | | | | | | | | | | | | | | | | enter/exit data directives. Support for the following OpenMP 4.5 restriction on 'target enter data' and 'target exit data': - A map-type must be specified in all map clauses. I have to save 'IsMapTypeImplicit' when parsing a map clause to support this constraint and for more informative error messages. This helps me support the following case: #pragma omp target enter data map(r) // expected-error {{map type must be specified for '#pragma omp target enter data'}} and distinguish it from: #pragma omp target enter data map(tofrom: r) // expected-error {{map type 'tofrom' is not allowed for '#pragma omp target enter data'}} Patch by Arpith Jacob. Thanks! llvm-svn: 258179

* Set the objc constraint on the context based on the parsed files.Pete Cooper2016-01-193-0/+81
| | | | | | | | | | | | Like arch, os, etc, when we know we are going to use a file, we check that the file has compatible objc constraints to the context, throw appropriate errors where that is not the case, and hopefully set the objc constraints on the context for use later. Added 2 tests to ensure that we don't have incompatibilities between host and simulator code as both will get x86 based architectures. llvm-svn: 258173

| | | | | | | | | | Image info flags describe the objc constraint which is GC/retain/release/etc. These need to be parsed and stored in the file so that we can do error checking. That will come in a later commit. llvm-svn: 258160

* [GC] Registry initialization and linkage interactionsPhilip Reames2016-01-193-8/+17
| | | | | | | | | | | | | | The Registry class constructs a linked list of nodes whose storage is inside static variables and nodes are added via static initializers. The trick is that those static initializers are in both the LLVM code base, and some random plugin that might get loaded in at runtime. The existing code tries to use C++ templates and their ODR rules to get a single definition of the registry for each type, but, experimentally, this doesn't quite work as designed. (Well, the entire structure doesn't. It might not actually be an ODR problem.) Previously, when I tried moving the GCStrategy class (along with it's registry) from CodeGen to IR, I ran into a problem where asking the GCStrategyRegistry a question would return inconsistent results depending on whether you asked from CodeGen (where the static initializers still were) or Transforms. My best guess is that this is a result of either a) an order of initialization error, or b) we ended up with two copies of the registry being created. I remember at the time having convinced myself it was probably (b), but I don't have any of my notes around from that investigation any more. See http://reviews.llvm.org/rL226311 for the original patch in question. This patch tries to remove the possibility of (b) above. (a) was already fixed in change 258109.

* Add clarifying comments defining what a Loop isPhilip Reames2016-01-191-0/+9
| | | | | | | | Our loop construct is not a way to identify cycles in the CFG. This wasn't immediately obvious from the header, so clarify that fact. The motivation for this was that I just fixed a out of tree bug due to a mistaken assumption (on my part) on what a Loop actually was. While it was fresh in my mind, I wanted to document the key point. llvm-svn: 258154
* [LibCallSimplifier] use instruction-level fast-math-flags to transform ↵Sanjay Patel2016-01-192-25/+23
| | | | | | | | | | | | | | | | | | pow(x, [small integer]) calls This is a continuation of adding FMF to call instructions: http://reviews.llvm.org/rL255555 As with D15937, the intent of the patch is to preserve the current behavior of the transform except that we use the pow call's 'fast' attribute as a trigger rather than a function-level attribute. The TODO comment notes a potential follow-on patch that would propagate FMF to the new instructions. Differential Revision: http://reviews.llvm.org/D16122 llvm-svn: 258153
* Module Debugging: Defer the emission of anonymous tag declsAdrian Prantl2016-01-194-0/+31

This fixes a regression introduced in r256962: When building debug info for a typdef'd anonymous tag type, we would be visiting the inner anonymous type first thus creating a "typedef changes linkage of anonymous type, but linkage was already computed" error. rdar://problem/24199640 llvm-svn: 258152

* [cmake] Fix add_version_info_from_vcs git svn version bug.Geoff Berry2016-01-191-17/+9
| | | | | | | | | | | | | | | | | | | | Summary: add_version_info_from_vcs was setting SVN_REVISION to the last fetched svn revision when using git svn instead of the svn revision corresponding to HEAD. This leads to conflicts with the definition of SVN_REVISION in SVNVersion.inc generated by GetSVN.cmake when HEAD is not the most recently fetched svn revision. Use 'git svn info' to determine SVN_REVISION when git svn is being used instead (as is done in GetSVN.cmake).

| | | | | | | | | Teach the register stackifier to rematerialize constants that have multiple uses instead of leaving them in registers. In the WebAssembly encoding, it's the same code size to materialize most constants as it is to read a value from a register. llvm-svn: 258142
