--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> ---
Alex - in a series of
# DEBUG x => ...
# DEBUG x => ...
# DEBUG x => ...
what are the rules of which ones we can remove? Can we always just keep the
last? What about location differences? What about possibly interleaving
DEBUG_BEGIN stmts?
For the quoted example
# DEBUG aFirst => NULL
# DEBUG aArgs#0 => NULL
# DEBUG this => NULL
# DEBUG this => NULL
# DEBUG aFirst => NULL
# DEBUG this => NULL
# DEBUG this => NULL
# DEBUG aFirst => NULL
# DEBUG this => NULL
# DEBUG aFirst => NULL
# DEBUG aArgs#0 => NULL
# DEBUG this => NULL
# DEBUG aFirst => NULL
# DEBUG aArgs#0 => NULL
# DEBUG aArgs#1 => NULL
# DEBUG this => NULL
I fear the simple way of matching only adjacent stmts isn't catching all
possibilities. Using a bitmap might be possible but can be also expensive.
