c-family: Prevent -Wformat warnings with u8 strings [PR105626]
The <https://gcc.gnu.org/pipermail/gcc/2022-May/238679.html> thread
seems to have concluded that -Wformat shouldn't warn about
printf((const char*) u8"test %d\n", 1);
saying "format string is not an array of type 'char'". This code
is not an aliasing violation, and there are no I/O functions for u8
strings, so the const char * cast is OK and shouldn't be disregarded.
PR c++/105626
gcc/c-family/ChangeLog:
* c-format.cc (check_format_arg): Don't emit -Wformat warnings with
u8 strings.
gcc/testsuite/ChangeLog:
* g++.dg/warn/Wformat-char8_t-1.C: New test.
