Formatting a std::optional<T> where T had a custom format_as(T) function failed to compile with clang,
due to set_debug_format being hidden by private inheritance. This fix makes the function available through a using clause.
This resolves the following finding reported by Coverity Static Analysis
v2023.6.1 on line 1964 of fmt/include/fmt/format.h:
ptr_arith: Using &v as an array. This might corrupt or misinterpret
adjacent memory locations.
* fix: make std::bitset formattable again
It used to be formattable via operator<<(ostream&) implicitly. Make it
formattable again, but this time via formatter specialization.
* fix: make nested_formatter constexpr default constructible
* Workaround intel bug
Potential workaround / restructure for the intel bug that is the cause of #3645.
Make the variable in the external struct instead an embedded static constexpr variable in the only function that uses the variable.
* Finish the proposed change -- remove struct accessor
* Refactor proposed intel fix.
Moved variable out of function to avoid specialization on Float. Made it a separate function that is called from format_float.
* Fix incorrect function name.
* Add missing inline.
* Avoid a space in the UDL definition except on GCC before 4.9
Clang 18 has grown a warning about the space being deprecated which
is enabled by default in their nightly binaries. However GCC before 4.9
will reject the UDL definition unless there is a space there, so we need
to keep the space conditionally for it.
* Remove UDLs on GCC before 4.9 to simplify things
GCC before 4.9 rejects the syntax that is now
rejected on more modern compilers.
* Disable compile-error-test on GCC < 4.9
This avoids the UDL tests failing as GCC < 4.9 can not parse UDLs
without a space, but the space is malformed in modern compilers.
- Removal of direct access to members of uint128_fallback and instead
create the values at the callsite and pass them via the constructor of
uint128_fallback on the return statement.
* FMT_EXPORT reorganization to fix compile error
- When compiling with FMT_MODULE, an error was being generated due to
use of FMT_EXPORT on a declaration within FMT_BEGIN_EXPORT and
FMT_END_EXPORT on `include/core.h`
- On `include/format.h` had to exclude the function vformat_to by ending
the export block just before it and beginning a new one after it.
