* Change memcpy/memove/memset to have dest and source alignment attributes.Daniel Neilson2018-01-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This change is step three in the series of changes to remove alignment argument from memcpy/memmove/memset in favour of alignment attributes. Steps: Step 1) Remove alignment parameter and create alignment parameter attributes for memcpy/memmove/memset. ( rL322965, rC322964, rL322963 ) Step 2) Expand the IRBuilder API to allow creation of memcpy/memmove with differing source and dest alignments. ( rL323597 ) Step 3) Update Clang to use the new IRBuilder API. Step 4) Update Polly to use the new IRBuilder API. Step 5) Update LLVM passes that create memcpy/memmove calls to use the new IRBuilder API, and those that use use MemIntrinsicInst::[get|set]Alignment() to use getDestAlignment() and getSourceAlignment() instead. Step 6) Remove the single-alignment IRBuilder API for memcpy/memmove, and the MemIntrinsicInst::[get|set]Alignment() methods.

* Change memcpy/memove/memset to have dest and source alignment attributes ↵Daniel Neilson2018-01-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | (Step 1). Summary: Upstream LLVM is changing the the prototypes of the @llvm.memcpy/memmove/memset intrinsics. This change updates the Clang tests for this change. The @llvm.memcpy/memmove/memset intrinsics currently have an explicit argument which is required to be a constant integer. It represents the alignment of the dest (and source), and so must be the minimum of the actual alignment of the two. This change removes the alignment argument in favour of placing the alignment attribute on the source and destination pointers of the memory intrinsic call. For example, code which used to read: call void @llvm.memcpy.p0i8.p0i8.i32(i8* %dest, i8* %src, i32 100, i32 4, i1 false) will now read call void @llvm.memcpy.p0i8.p0i8.i32(i8* align 4 %dest, i8* align 4 %src, i32 100, i1 false) At this time the source and destination alignments must be the same (Step 1). Step 2 of the change, to be landed shortly, will relax that contraint and allow the source and destination to have different alignments. llvm-svn: 322964

* 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.

* [ms-cxxabi] Use inalloca on win32 when passing non-trivial C++ objectsReid Kleckner2014-02-011-3/+6
| | | | | | | | | | | | | | | | | | | When a non-trivial parameter is present, clang now gathers up all the parameters that lack inreg and puts them into a packed struct. MSVC always aligns each parameter to 4 bytes and no more, so this is a pretty simple struct to lay out. On win64, non-trivial records are passed indirectly. Prior to this change, clang was incorrectly using byval on win64. I'm able to self-host a working clang with this change and additional LLVM patches.

* Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar2009-12-151-1/+1
| | | | | | | | | - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). llvm-svn: 91446
