From: Tom Tromey Date: Wed, 15 Jan 2014 16:30:05 +0000 (-0700) Subject: pass NULL to TARGET_DEFAULT_RETURN when appropriate X-Git-Tag: gdb-7.8-release~1061 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9b1440374cbe716ac5dab4d3092e67089db36fa5;p=platform%2Fupstream%2Fbinutils.git pass NULL to TARGET_DEFAULT_RETURN when appropriate This changes instances of TARGET_DEFAULT_RETURN(0) to TARGET_DEFAULT_RETURN(NULL) when appropriate. The use of "0" was a relic from an earlier implementation of make-target-delegates; and I didn't want to go back through the long patch series, fixing up conflicts, just to change this small detail. 2014-02-19 Tom Tromey * target-delegates.c: Rebuild. * target.h (struct target_ops) : Use NULL, not 0, in TARGET_DEFAULT_RETURN. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 0dd90ca..7496e3b 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,13 @@ 2014-02-19 Tom Tromey + * target-delegates.c: Rebuild. + * target.h (struct target_ops) : Use NULL, + not 0, in TARGET_DEFAULT_RETURN. + +2014-02-19 Tom Tromey + * target.c (complete_target_initialization): Remove casts.
