I had intended to support the P2510R3 proposal unconditionally in C++20 mode, but I left it half implemented. The parse function supported the new extensions, but the format function didn't. This adds the missing pieces, and makes it only enabled for C++26 and non-strict modes. libstdc++-v3/ChangeLog: PR libstdc++/110149 * include/std/format (formatter<const void*, charT>::parse): Only alow 0 and P for C++26 and non-strict modes. (formatter<const void*, charT>::format): Use toupper for P type, and insert zero-fill characters for 0 option. * testsuite/std/format/functions/format.cc: Check pointer formatting. Only check P2510R3 extensions conditionally. * testsuite/std/format/parse_ctx.cc: Only check P2510R3 extensions conditionally. |
