------- Comment #1 from rguenth at gcc dot gnu dot org 2007-10-03 21:02 -------
-frtl-abstract-sequences
It is a size optimization method. This option is to find identical
sequences of code, which can be turned into pseudo-procedures and then replace
all occurrences with calls to the newly created subroutine. It is kind of an
opposite of -finline-functions. This optimization runs at RTL level.
I propose to kill all traces of it unless someone steps up and maintains this
piece of code and we enable it for -Os.
