Subject: Support for 64-bit location_t: toplev parts
X-Git-Tag: basepoints/gcc-16~3724
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8cc9d27e2db7d9f4867061c848c2d2c46a101371;p=thirdparty%2Fgcc.git

Support for 64-bit location_t: toplev parts

With the upcoming move from 32-bit to 64-bit location_t, the recommended
number of range bits will change from 5 to 7. line-map.h now exports the
recommended setting, so use that instead of hard-coding 5.

gcc/ChangeLog:

	* toplev.cc (general_init): Replace hard-coded constant with
	line_map_suggested_range_bits.
