| | | | | | | | | | | | | | | | | compatible to what the runtime library expects. Summary: This patch fixes an issue detected when firstprivate variables are passed to an OpenMP outlined function vararg list. Currently they are not compatible with what the runtime library expects causing malfunction in some targets. This patch fixes the issue by moving the casting logic already in place for offloading to the common code that creates the outline function and arguments and updates the regression tests accordingly.

* [OPENMP] Pass scalar firstprivate vars by value.Alexey Bataev2016-05-171-8/+16
| | | | | | | | For better performance and to unify code with offloading part we pass scalar firstprivate values by value, instead of by reference. It will remove some extra copying operations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@269751 91177308-0d34-0410-b5e6-96231b3b80d8
* [OPENMP] Allow runtime insert its own code inside OpenMP regions.Alexey Bataev2016-03-291-5/+5
| | | | | | | | | | Solution unifies interface of RegionCodeGenTy type to allow insert runtime-specific code before/after main codegen action defined in CGStmtOpenMP.cpp file.

* Change memcpy/memset/memmove to have dest and source alignments.Pete Cooper2015-11-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | This is a follow on from a similar LLVM commit: r253511. Note, this was reviewed (and more details are in) http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20151109/312083.html These intrinsics currently have an explicit alignment argument which is required to be a constant integer. It represents the alignment of the source and dest, and so must be the minimum of those. This change allows source and dest to each have their own alignments by using the alignment attribute on their arguments. The alignment argument itself is removed. The only code change to clang is hidden in CGBuilder.h which now passes both dest and source alignment to IRBuilder, instead of taking the minimum of dest and source alignments.

* Stop messing with the 'g' group of options in CompilerInvocation.Douglas Katzman2015-10-081-1/+1
| | | | | | | | | | | | | | | | With this change, most 'g' options are rejected by CompilerInvocation. They remain only as Driver options. The new way to request debug info from cc1 is with "-debug-info-kind={line-tables-only|limited|standalone}" and "-dwarf-version={2|3|4}". In the absence of a command-line option to specify Dwarf version, the Toolchain decides it, rather than placing Toolchain-specific logic in CompilerInvocation. Also fix a bug in the Windows compatibility argument parsing in which the "rightmost argument wins" principle failed.

This reapplies r230044 with a fixed configure+make build and updated dependencies and testcase requirements.
