operand of a VECTOR_SHUFFLE. The mask is a vector of constant integers. The code in LegalizeDAG doesn't bother to legalize the mask, since it's basically just storage for a bunch of constants, however LegalizeTypes is more picky. The problem is that there may not exist any legal vector-of-integers type with a legal element type, so it is impossible to create a legal mask! Unless of course you cheat by creating a BUILD_VECTOR where the operands have a different type to the element type of the vector being built... This is pretty ugly but works - all relevant tests in the testsuite pass, and produce the same assembler with and without LegalizeTypes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47670 91177308-0d34-0410-b5e6-96231b3b80d8 |
