giulianobelinassi updated this revision to Diff 519131.
giulianobelinassi added a comment.
Incorporate some of Aron suggestions:
- Replace isDeclspecAttribute with isStandardAttributeSyntax
- Avoid multiple calls to getAsFunction
- Use AttrPrintLoc:: instead of referencing the value directly
- Also output enable_if on the right side of decl.
