[PATCH] Remove Pascal language in source code.

["Martin Liška" <mliska@suse.cz>]

[-- Attachment #1: Type: text/plain, Size: 796 bytes --]

Hi.

Similar for GNU Pascal language.

Patch can bootstrap on ppc64le-redhat-linux and survives regression tests.

Ready to be installed?

gcc/ChangeLog:

2017-07-11  Martin Liska  <mliska@suse.cz>

	* dbxout.c (get_lang_number): Do not handle GNU Pascal.
	* dbxout.h (extern void dbxout_stab_value_internal_label_diff):
	Remove N_SO_PASCAL.
	* dwarf2out.c (lower_bound_default): Do not handle
	DW_LANG_Pascal83.
	(gen_compile_unit_die): Likewise.
