Bug ID: 36987
Summary: Add support for optimization remarks at MC level
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: MC
Assignee: unassignedb...@nondot.org
Reporter: franci...@yahoo.com
CC: llvm-bugs@lists.llvm.org
There is currently no way to emit optimisation remark at the MC level.
It would be nice to have this, at least per function with the source location
being the function definition.
One use case I want from this is emitting remarks for compact unwinding:
"compact unwinding cannot represent this function, falling back on DWARF".
