Bug ID: 35158
Summary: ToT llvm+clang crashes when building ToT llvm+clang
with "-march=knl”
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Backend: X86

CC: llvm-bugs at lists.llvm.org
ToT llvm+clang crashes when building ToT llvm+clang with "-march=knl”.
Sorry, I don't have any of the metadata it requested handy. I did try and debug
it a little bit though. It looks like a v64i8 register was requested, but "knl"
doesn't support that register class. Maybe some custom lowering is missing? Or
maybe a missing HasBWI flag is needed in the instruction tables?
