* change an assert when generating fmuladd to an ordinary 'if' check (PR25719)Sanjay Patel2015-12-032-11/+21
| | | | | | | | | | | | | | | | | | | We don't want to generate fmuladd if there's a use of the fmul expression, but this shouldn't be an assert. The test case is derived from the commit message for r253337: http://reviews.llvm.org/rL253337 That commit reverted r253269: http://reviews.llvm.org/rL253269 ...but the bug exists independently of the default fp-contract setting. It just became easier to hit with that change. PR25719: https://llvm.org/bugs/show_bug.cgi?id=25719 Differential Revision: http://reviews.llvm.org/D15165 llvm-svn: 254573

* Switch the linker to having a whitelist of GVs.Rafael Espindola2015-12-022-55/+71
| | | | | | | | | | | | This replaces DoNotLinkFromSource with ValuesToLink. It also moves the computation of ValuesToLink earlier. It is a bit simpler and an important step in slitting the linker into an ir mover and a linker proper. The test change is because we now avoid creating dead declarations. llvm-svn: 254559

The Details section has tags that should get picked up using the normal issue text scrapers (e.g. buildbot). Test numbers reported are strictly test method runs. The rerun bit at the top is in support of the multi-pass test runner code (to run the low-load, single worker test pass for tests that failed the first run), which I'll be able to put up for review after this. ResultsFormatters now have the ability to indicate they replace the legacy summary, as this one does. Once we come to agreement on the exact format, I will switch us over to using this by default. llvm-svn: 254530

* [OpenMP] Update target directive codegen to use 4.5 implicit data mappings.Samuel Antao2015-12-0212-269/+1639
| | | | | | | | | | | | | | | Summary: This patch implements the 4.5 specification for the implicit data maps. OpenMP 4.5 specification changes the default way data is captured into a target region. All the non-aggregate kinds are passed by value by default. This required activating the capturing by value during SEMA for the target region. All the non-aggregate values that can be encoded in the size of a pointer are properly casted and forwarded to the runtime library. On top of fixing the previous weird behavior for mapping pointers in nested data regions (an explicit map was always required), this also improves performance as the number of allocations/transactions to the device per non-aggregate map are reduced from two to only one - instead of passing a reference and the value, only the value passed. Explicit maps will be added later on once firstprivate, private, and map clauses' SEMA and parsing are available.
