Subject: line-map.c (linemap_enter_macro): Don't zero max_column_hint in every macro.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d86d21192b13e6b1b92a10d5493d3e36b7f1a50c;p=gcc.git

line-map.c (linemap_enter_macro): Don't zero max_column_hint in every macro.

 	* line-map.c (linemap_enter_macro): Don't zero max_column_hint in
 	every macro. This improves performance by reducing the number of
 	reallocations when track-macro-expansion is on.
