In InnerLoopVectorizer::getOrCreateTripCount, when the backedge taken count is a SCEV add expression, its type is defined by the type of the last operand of the add expression. In the test case from PR45259, this last operand happens to be a pointer, which (according to llvm::Type) does not have a primitive size in bits. In this case, LoopVectorize fails to truncate the SCEV and crashes as a result. Uing ScalarEvolution::getTypeSizeInBits makes the truncation work as expected. https://bugs.llvm.org/show_bug.cgi?id=45259 Differential Revision: https://reviews.llvm.org/D76669 |
