            Bug ID: 39055
           Summary: [llvm-exegesis] X86\Target.cpp:175 - ConstantInliner
                    assertion
           Product: new-bugs
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P

This assertion (X86\Target.cpp line 175) is firing:

assert(Constant.getBitWidth() % 8 == 0 && "Must be a multiple of 8");

whenever I run llvm-exegesis with a FPU operation:

llvm-exegesis -mode=uops -opcode-name=VADDPSrr  // ASSERTION

I can get it to run with FPU operations that start with a gpr:

llvm-exegesis -mode=uops -opcode-name=CVTSI2SDrr  // OK
