Bug ID: 37448
Summary: [llvm-exegesis] Include specific EFLAGS in the test
code
Product: new-bugs
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: new bugs

The test values for CMOVA/CMOVBE are underestimating the latency on SNB+
targets as it isn't handling the fact that those targets can update the EFLAGS
C bit independently from the OSPAZ bits.
These CMOV variants depend on the C and Z flags and thus need to be tested in
cases where both are touched.
