Subject: 	* remote.c (getpkt): If we get a timeout, actually retry rather
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0c9935502ff2db25eabe36ee00ddc3d4c02cf3ca;p=binutils-gdb.git

	* remote.c (getpkt): If we get a timeout, actually retry rather
	than just giving up the first time it happens.
	* remote.c: Document sequence numbers.
	(remote_store_registers): Change syntax of 'P' request so that it
	never looks like a sequence number.
