From a42e82976aac3aed9b966e611b3cfa98974c4978 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Thu, 7 Aug 2014 09:49:32 +0930 Subject: [PATCH] Merge WARN and CWARN cases in _bfd_generic_link_add_one_symbol WARN has always been able to be handled by the CWARN case (WARN was used when the previous symbols was undef, undefweak or common and thus must be on the undefs list, so the CWARN test passes). So let's merge those two cases. * linker.c (WARN, CWARN): Collapse these states to WARN. (_bfd_generic_link_add_one_symbol): Use old CWARN case for new WARN. --- bfd/linker.c | 12 ++---------- 1 file changed, 2 insertions(+), 10 deletions(-) diff --git a/bfd/linker.c b/bfd/linker.c index 1877e67ea0..93c5465e06 100644 --- a/bfd/linker.c +++ b/bfd/linker.c @@ -1342,8 +1342,7 @@ enum link_action CIND, /* Make indirect symbol from existing common symbol. */ SET, /* Add value to set. */ MWARN, /* Make warning symbol. */ - WARN, /* Issue warning. */ - CWARN, /* Warn if referenced, else MWARN. */ + WARN, /* Warn if referenced, else MWARN. */ CYCLE, /* Repeat with symbol pointed to. */ REFC, /* Mark indirect symbol referenced and then CYCLE. */ WARNC /* Issue warning and then CYCLE. */ @@ -1361,7 +1360,7 @@ static const enum link_action link_action[8][8] = /* DEFW_ROW */ {DEFW, DEFW, DEFW, NOACT, NOACT, NOACT, NOACT, CYCLE }, /* COMMON_ROW */ {COM, COM, COM, CREF, COM, BIG, REFC, WARNC }, /* INDR_ROW */ {IND, IND, IND, MDEF, IND, CIND, MIND, CYCLE }, - /* WARN_ROW */ {MWARN, WARN, WARN, CWARN, CWARN, WARN, CWARN, NOACT }, + /* WARN_ROW */ {MWARN, WARN, WARN, WARN, WARN, WARN, WARN, NOACT }, /* SET_ROW */ {SET, SET, SET, SET, SET, SET, CYCLE, CYCLE } }; @@ -1803,13 +1802,6 @@ _bfd_generic_link_add_one_symbol (struct bfd_link_info *info, break; case WARN: - /* Issue a warning. */ - if (!
