Summary: Invalid metadata is simply omitted, no warning
Product: libraries
Version: 2.7
Platform: Macintosh
OS/Version: MacOS X
Status: NEW
Severity: enhancement
Priority: P
Component: Common Code Generator Code
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
When outputting machine assembly llc will simply drop any debug metadata that
it malformed. This makes it very hard to figure out bugs (obviously).
Two recommended warnings to add:
- Return instruction must have a DebugLoc
- Subprogram name metadata must match function name
