This patch is fixing those tests:
20_util/to_chars/float128_c++23.cc
std/format/formatter/requirements.cc
std/format/functions/format.cc
std/format/functions/format_to_n.cc
std/format/functions/size.cc
std/format/functions/vformat_to.cc
std/format/string.cc
Note that symbols used in <format> for __ibm128 and __iee128 are untested.
I even wonder if the normal mode ones are because I cannot find the
symbols used in gnu.ver.
libstdc++: [_GLIBCXX_INLINE_VERSION] Add to_chars/from_chars
symbols export
libstdc++-v3/ChangeLog
* include/std/format [_GLIBCXX_INLINE_VERSION](to_chars):
Adapt __asm symbol
specifications.
* config/abi/pre/gnu-versioned-namespace.ver: Add
to_chars/from_chars symbols
export.
Ok to commit ?
