Subject: 	* aout-target.h, netbsd386.c: Replace NO_SWAP_MAGIC with SWAP_MAGIC,
X-Git-Tag: gdb-4_18~16215
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3f99570ec9e7026a8f4a2567029ef8231b9c1fbf;p=external%2Fbinutils.git

	* aout-target.h, netbsd386.c: Replace NO_SWAP_MAGIC with SWAP_MAGIC,
	and do the swapping here rather than calling ntohl from the N_*
	macros.  This cleans up assumptions about the size of a host long,
	the existence to ntohl, etc.
