Bug ID: 32216
Summary: [X86] Better testing of schedule model instruction
latencies/throughputs
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: X86

We don't currently do a very good job of testing the various costs of
instructions based on the specific schedule model used (generic, atom,
sandybridge, haswell, silvermont, jaguar).
To help improve this it would be useful to have an option to to output assembly
comments that indicate latency/throughput etc. of each instruction. We should
then create a set of test files that cover a decent range of instructions.
