- Subject: [patch] Remove LABEL_ALIGN_AFTER_BARRIER_MAX_SKIP.
Hi,
Attached is a patch to remove LABEL_ALIGN_AFTER_BARRIER_MAX_SKIP as
nobody overrides the macro.
>From ChangeLog.5, the last overriding definition of the macro was
removed on 2001-05-03 from i386.h.
Bootstrapped on i686-pc-linux-gnu. OK to apply?
p.s.
There are several macros of this kind (that is, almost unused) in
final.c. I am planning to clean up one by one.

* final.c (LABEL_ALIGN_AFTER_BARRIER_MAX_SKIP): Remove.
(shorten_branches): Hardcode the default value of
LABEL_ALIGN_AFTER_BARRIER_MAX_SKIP.
* system.h (LABEL_ALIGN_AFTER_BARRIER_MAX_SKIP): Poison.
* doc/tm.texi (LABEL_ALIGN_AFTER_BARRIER_MAX_SKIP): Remove.
