[cfe-commits] Patch for review: add a fixit to remove an unused label.

[Anna Zaks]

Hi,

Attached are two patches, which add a fixit to remove an unused label.

1) Add a utility function to the Lexer, which makes it easier to find the ':' after the label as well as the new line and trailing spaces (It is a generalized version of trans::findLocationAfterSemi from ArcMigrate, which will be changed to use the Lexer utility).


2) Generate the fixit.


Thanks,
Anna.
