Bug ID: 36256
Summary: [X86] Couple lit tests generate KMOVQ instructions on
KNL which doesn't support KMOVQ
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: X86
Assignee: unassignedb...@nondot.org
Reporter: craig.top...@gmail.com
CC: llvm-bugs@lists.llvm.org
While investing PR36254, I discovered that this two tests try to preserve
k-registers with a spill size of 64 bits which trigger us to use kmovq. But KNL
doesn't support KMOVQ/KMOVD and should use a spill size of 16 bits.
