Subject: Whitespace/comment cleanup.  Use PARAMS in tc-vax.c.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=43029a8f84e0684ba2c1e6e1643245cd80404ef2;p=binutils-gdb.git

Whitespace/comment cleanup.  Use PARAMS in tc-vax.c.
Make various routines return null pointer instead of empty string for
success indication.

+	* config/atof-vax.c (md_atof): Return null on success instead of
+	empty string.
+	* config/atof-tahoe.c (md_atof): Ditto.
+	* read.c (float_cons): Expect a null pointer for success, not an
+	empty string.
+
+	* hash.c (hash_insert, hash_jam, hash_grow): Return null pointer
+	on success, instead of empty string.  All callers changed.
+
+	* config/tc-vax.c: Use PARAMS in declarations.
+	(vip_op): Use NULL instead of empty string for success in error
+	and warning fields.
