Author: sepavloff Date: Thu Jun 8 00:25:19 2017 New Revision: 304963 URL: http://llvm.org/viewvc/llvm-project?rev=304963&view=rev Log: Catch invalid bitwise operation on vector of floats
Bitwise complement applied to vector of floats described with attribute `ext_vector_type` is not diagnosed as error. Attempt to compile such construct causes assertion violation in Instruction.cpp. With this change the complement is treated similar to the case of vector type described with attribute `vector_size`.
