X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b93c07227e9ce2ee03d1cdc5ae2250fef3b0c130;p=gcc.git

line-map.c (linemap_position_for_loc_and_offset): Add new linemap_assert_fails.

libcpp/ChangeLog:

2014-12-05  Manuel López-Ibáñez  <manu@gcc.gnu.org>

	* line-map.c (linemap_position_for_loc_and_offset): Add new
	linemap_assert_fails.

gcc/fortran/ChangeLog:

2014-12-05  Manuel López-Ibáñez  <manu@gcc.gnu.org>

	* scanner.c (gfc_next_char_literal): Use gfc_warning_now.
	(load_file): Use the line length as the column hint for
	linemap_line_start. Reserve a location for the highest column of
	the line.
