PR c++/88095, CTAD for literal operator templates per P0732
This patch fixes PR c++/88095: class nontype template parameter UDL string
literals doesn't accepts deduction placeholder
It also addresses a latent issue; literal operator templates with template
parameter packs of literal class type were previously accepted. The patch
corrects this and adds a test (udlit-class-nttp-neg.C).
This fix is needed for one of the char8_t remediation approaches documented
in P1423, and may be helpful for existing code bases impacted by the char8_t
changes adopted via P0482 for C++20.
gcc/cp/ChangeLog:
2019-08-02 Tom Honermann <tom@honermann.net>
* parser.c (cp_parser_template_declaration_after_parameters): Enable
class template argument deduction for non-type template parameters
in literal operator templates.
