* AVX-512: Lowering Masked Gather intrinsic - fixed a bugElena Demikhovsky2017-06-227-18/+165
| | | | | | | | | | | | Masked gather for vector length 2 is lowered incorrectly for element type i32. The type <2 x i32> was automatically extended to <2 x i64> and we generated VPGATHERQQ instead of VPGATHERQD. The type <2 x float> is extended to <4 x float>, so there is no bug for this type, but the sequence may be more optimal. In this patch I'm fixing <2 x i32>bug and optimizing <2 x float> sequence for GATHERs only. The same fix should be done for Scatters as well.

* SwiftCC: Perform physical layout when computing coercion typesArnold Schwaighofer2017-06-212-1/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | We need to take type alignment padding into account whe computing physical layouts. The layout must be compatible with the input layout, offsets are defined in terms of offsets within a packed struct which are computed in terms of the alloc size of a type. Usingthe store size we would insert padding for the following type for example: struct { int3 v; long long l; } __attribute((packed)) On x86-64 int3 is padded to int4 alignment. The swiftcc type would be <{ <3 x float>, [4 x i8], i64 }> which is not compatible with <{ <3 x float>, i64 }>. The latter has i64 at offset 16 and the former at offset 20. rdar://32618125 llvm-svn: 305956

* [BasicAA] Use MayAlias instead of PartialAlias for fallback.Michael Kruse2017-06-2113-87/+107
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using various methods, BasicAA tries to determine whether two GetElementPtr memory locations alias when its base pointers are known to be equal. When none of its heuristics are applicable, it falls back to PartialAlias to, according to a comment, protect TBAA making a wrong decision in case of unions and malloc. PartialAlias is not correct, because a PartialAlias result implies that some, but not all, bytes overlap which is not necessarily the case here. AAResults returns the first analysis result that is not MayAlias. BasicAA is always the first alias analysis. When it returns PartialAlias, no other analysis is queried to give a more exact result (which was the intention of returning PartialAlias instead of MayAlias). For instance, ScopedAA could return a more accurate result. The PartialAlias hack was introduced in r131781 (and re-applied in r132632 after some reverts) to fix llvm.org/PR9971 where TBAA returns a wrong NoAlias result due to a union. A test case for the malloc case mentioned in the comment was not provided and I don't think it is affected since it returns an omnipotent char anyway. Since r303851 (https://reviews.llvm.org/D33328) clang does emit specific TBAA for unions anymore (but "omnipotent char" instead). Hence, the PartialAlias workaround is not required anymore. This patch passes the test-suite and check-llvm/check-clang of a self-hoisted build on x64. Reviewed By: hfinkel Differential Revision: https://reviews.llvm.org/D34318 llvm-svn: 305938

* [PDB] Add symbols to the PDBReid Kleckner2017-06-216-10/+659
| | | | | | | | | | | | | | | | | | | Summary: The main complexity in adding symbol records is that we need to "relocate" all the type indices. Type indices do not have anything like relocations, an opaque data structure describing where to find existing type indices for fixups. The linker just has to "know" where the type references are in the symbol records. I added an overload of `discoverTypeIndices` that works on symbol records, and it seems to be able to link the standard library.
