Subject: * putenv.c:  index -> strchr.
X-Git-Tag: gdb-4_18~20979
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b38f304c4fc12ec5c3d496cb908ad2d2703d67ad;p=external%2Fbinutils.git

* putenv.c:  index -> strchr.
* regex.c:  Always rename bcopy to memcpy, etc.
FIXME:  Eventually do the renames rather than use #define's.
* sparc-tdep.c (deferred_stores):  Moved from sparc-xdep.c.
Fix bcopy->memcpy.
* sparc-xdep.c:  Move deferred_stores to target dependent.
