Author: dim Date: Tue Oct 13 19:42:22 2020 New Revision: 366683 URL: https://svnweb.freebsd.org/changeset/base/366683 Log: Merge commit 35ecc7fe4 from llvm git (by Hubert Tong): [clang][Sema] Fix PR47676: Handle dependent AltiVec C-style cast Fix premature decision in the presence of type-dependent expression operands on whether AltiVec vector initializations from single expressions are "splat" operations. Verify that the instantiation is able to determine the correct cast semantics for both the scalar type and the vector type case. Note that, because the change only affects the single-expression case (and the target type is an AltiVec-style vector type), the replacement of a parenthesized list with a parenthesized expression does not change the semantics of the program in a program-observable manner. Reviewed By: aaron.ballman Differential Revision: https://reviews.llvm.org/D88526 This should fix 'Assertion failed: (isScalarType()), function getScalarTypeKind, file /usr/src/contrib/llvm-project/clang/lib/AST /Type.cpp, line 2146', when building the graphics/opencv-core port for powerpc64le.
