Commit Message

Joseph Myers Dec. 3, 2024, 1:03 p.m. UTC 
  As noted in bug 117162, C23 changed some rules on UCNs to match C++
(this was a late change agreed in the resolution to CD2 comment
US-032, implementing changes from N3124), which we need to implement.

Allow UCNs below 0xa0 outside identifiers for C, with a
pedwarn-if-pedantic before C23 (and a warning with -Wc11-c23-compat)
except for the always-allowed cases of UCNs for $ @ `.  Also as part
of that change, do not allow \u0024 in identifiers as equivalent to $
for C23.

Bootstrapped with no regressions for x86_64-pc-linux-gnu.

	PR c/117162

libcpp/
	* include/cpplib.h (struct cpp_options): Add low_ucns.
	* init.cc (struct lang_flags, lang_defaults): Add low_ucns.
	(cpp_set_lang): Set low_ucns
	* charset.cc (_cpp_valid_ucn): For C, allow UCNs below 0xa0
	outside identifiers, with a pedwarn if pedantic before C23 or a
	warning with -Wc11-c23-compat.  Do not allow \u0024 in identifiers
	for C23.
