Bug ID: 45091
Summary: [x86] update_llc_test_checks - don't hide useful
address math
Product: tools
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: support scripts

By default we hide address math for many loads/stores in the x86 asm output
checks, which prevents us from seeing sometimes critical changes (offset
changes, stack positions etc.).
It's probably a large diff but always exposing this is probably a good idea.
We can probably reduce this at least a little by merging 32-bit/64-bit stack
variants (esp/rsp etc.) in regex patterns.
And some addresses we don't care about (constant pool loads?) so we should
still try to hide those.
