            Bug ID: 45094
           Summary: [X86] Always use fixed-width hex values for asm
                    constant comments
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Backend: X86
          Assignee: unassignedbugs at nondot.org

This would be a big diff but consistently using fixed-width hex values for all
x8 asm comments constant vectors would help improve debugging a great deal.

We have a lot of weird cases in the comments with base10 integers being used
for float/double values, and doubles being used for i64 on 32-bit targets.
