[pushed] c++: handle _FloatNN redeclaration like bool [PR107128]
Checks
Commit Message
Tested x86_64-pc-linux-gnu, applying to trunk.
-- 8< --
It's been inconvenient to compile testcases preprocessed with GCC 12 or
earlier because they break on
typedef __float128 _Float128;
We already had code for handling this with bool and wchar_t, it just needs
to be extended to _FloatNN as well.
PR c++/107128
gcc/cp/ChangeLog:
* parser.cc (cp_parser_set_decl_spec_type): Use
redefined_builtin_type for extended_float_type_p.
gcc/testsuite/ChangeLog:
* g++.dg/warn/pragma-system_header6.h: New test.
* g++.dg/warn/pragma-system_header6.C: New test.
