This is a pre-existing problem that std::to_chars for floating-point types
doesn't work on these targets. Until I started to use std::format in
std/c++20/tzdb.cc the library wasn't using that, so the missing feature only
caused testsuite failures.

I have a workaround for this, but bootstrap still fails for me at:

    libstdc++: Disable broken std::format for floating-point types [PR108221]

    If we don't have std::to_chars for floating-point types (either because
    float and double are not IEEE format, or size_t is 16-bit) then we can't
    use them with std::format. This causes a bootstrap failure since
    std/c++20/tzdb.cc was added to the library, because <chrono> now
    includes <format>.

    This change just disables formatting support for those types. This is
    not a proper fix, but solves the bootstrap failure for now.

    libstdc++-v3/ChangeLog:

            PR libstdc++/108221
            * include/std/format (basic_format_arg) [!__cpp_lib_to_chars]:
            Disable visiting floating-point types.

Fixed, but the build still fails as mentioned above.

Jonathan, I am not sure to what part of the thread "above" refers to, but build
fails indeed. This time due to a different reason. This is what I got when I
was trying to build f7bd48c6. Please note -mn -mint32 options – normal mode
(aka 16-bit mode) with 32-bit integers.

Has this bizarre mode ever been able to build libstdc++?

I have too many other things to deal with to care about this odd target, sorry.

The reason it fails is here:

D:/Works/xcomp/gcc-build/h8300-elf/normal/int32/libstdc++-v3/include/span:147:7:
note: candidate: 'constexpr std::span<_Type, _Extent>::span() requires  _Extent
+ 1 <= 1 [with _Type = char; short unsigned int _Extent = 65535]'
  147 |       span() noexcept
      |       ^~~~
D:/Works/xcomp/gcc-build/h8300-elf/normal/int32/libstdc++-v3/include/span:147:7:
note: constraints not satisfied

The requires expression fails if size_t promotes to int, which is true for
bizarre mode.

--- Comment #10 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The fix would be changing the constraint to:


_Extent == dynamic_­extent || _Extent == 0

Yes, it was possible to build libstdc++ in this mode before introduction of all
that C++20 time zone stuff in 9fc61d45. E.g. I am able to build 907c84cb which
is parent of 9fc61d45.

That being said, the normal mode is indeed "bizzare" and I can't imagine myself
why one would want to use it these days, when the original 16-bit H8/300 died a
long time ago and its descendants are just dying. Perhaps support for normal
mode should be removed just like support for H8/300 was in mid-2020 (as far as
I remember).

--- Comment #12 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The std::span default constructor that's causing problems has been there for a
few years, but nobody pointed out it didn't work for this mode. For a target to
remain usable we need test results and regular fixes. Otherwise things stay
broken for years and then we have to fix dozens of things all at once. This
target has bitrotted quite badly.

FYI, Jonathan. This time the target is msp430-elf.

    libstdc++: Fix std::span constraint for sizeof(size_t) < sizeof(int)
[PR108221]

    The default constructor has a constraint that is always false if
    arithmetic on size_t values promotes to int. Rewrite the constraint
    exactly as written in the standard, which works correctly.

    libstdc++-v3/ChangeLog:

            PR libstdc++/108221
            * include/std/span (span::span()): Un-simplify constraint to
            work for size_t of lesser rank than int.

    libstdc++: Fix some algos for 16-bit size_t [PR108221]

    Some standard algorithms fail to compile when size_t or ptrdiff_t is
    narrower than int. The __lg helper function is ambiguous if ptrdiff_t is
    short or __int20, so replace it with a function template that works for
    those types as well as signed/unsigned int/long/long long. The helpers
    for stable_sort perform arithmetic on size values and assume the types
    won't change, which isn't true if the type promotes to int.

    libstdc++-v3/ChangeLog:

            PR libstdc++/108221
            * include/bits/stl_algobase.h (__lg): Replace six overloads with
            a single function template for all integer types.
            * include/bits/stl_algo.h (__merge_adaptive_resize): Cast
            arithmetic results back to _Distance.

Please try current master, I think the errors for h8300-elf and msp430-elf
should be fixed (but I still get the assembler errors for h8300-elf using
latest binutils).

Thanks Jonathan. I confirm – I have successfully built master (554bb9b6) for
both targets. Although I'm still using binutils 2.39, I haven't tried its
current master yet.

This is strange. I have just successfully built binutils edf64cd2 and then gcc
426a9f55.

Strange, maybe something different about my newlib build. Anyway, what matters
is that you can build it. I only need to be able to verify my changes compile!
