Subject: 	Ideas from Srinivas Addagarla <srinivas@cdotd.ernet.in>:
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a6b200da04cf5af5edafc94b4bd72747658ca5fd;p=binutils-gdb.git

	Ideas from Srinivas Addagarla <srinivas@cdotd.ernet.in>:
	* read.c (read_a_source_file): After doing an mri_pending_align,
	adjust the line_label if there is one.
	(s_space): Set mri_pending_align if an odd number of bytes were
	output.
