When building with -Werror,-Wsigned-enum-bitfield clang reports that "enums in the Microsoft ABI are signed integers by default; consider giving the enum type an unsigned underlying type to make this code portable" for these two types.
Under this ABI one bit of an enum bitfield is used by the sign bit. Enum values large enough to overlap that bit would be seen as negative integers if read out into an integer.
There may not be any such reading out at present, but making the underlying type unsigned ensures consistent results across platforms.
The current `FMT_FORMAT_AS` macro will make `formatter<Char *>::format`
have the first argument type `const Char *&` which is incorrect an
should be `Char *const &`. This pull request fixes that by changing the
first argument type in the macro definition body from `const Type &` to
`Type const &`.
Make FMT_API symbols use the default visibility on non-Windows
platforms. Otherwise, one cannot use the generated fmt library when
compiling globally with -fvisibility=hidden.
Fixes compile errors like:
```
../3rdParty/fmt/include/fmt/core.h:757: error: undefined reference to 'fmt::v6::internal::assert_fail(char const*, int, char const*)'
```
Note that the symbol exists, but is local:
```
$ nm -C libfmtd.so.6.1.3 | grep assert_fail
U __assert_fail
0000000000233ffa t fmt::v6::internal::assert_fail(char const*, int, char const*)
```
With this patch, the compile error is gone and the symbol is properly
exported:
```
$ nm -a bin/libfmtd.so -C | grep assert_fail
U __assert_fail
00000000002366ba T fmt::v6::internal::assert_fail(char const*, int, char const*)
```
Change-Id: I96054e622d9a2ae81907e1b01a1033e629767a91
* Fix formatting chrono durations to wide strings
* Make format buffers const correct
* Add FormatWide chrono test case
* Fix incorrect wide encoding of 'µs'
I think might be a source file encoding issue, so I used \u00B5 instead.
* Update FormatWide test to use proper encoding of µs
* Revert changes to format_localized's parameters
* Use different overload of `std::time_put<T>::put` to avoid needing a format string
* Use utf8_to_utf16 instead of having redundant overloads of get_units
* Revert some minor changes
* Remove FMT_CONSTEXPR from expression
This should hopefully fix compilation on VS <2019
* Make suggested changes from code review
* Run clang-format on chrono.h
* Make sure unit isn't null before constructing a string_view from it
If `FMT_STATIC_THOUSANDS_SEPARATOR` defined, then locale is not included or defined, so this call will be unresolved. I think this is the correct fix based on the code in `format-inl.h` and `format.h`
## Problem
In the case of an existing `fmt` namespace (in my project this looks like `Project::fmt`) it is possible to get a namespace clash in debug builds (MSVC 2017)
## Proposed Solution
When referencing `fmt` internally, be explicit that it is relative to the global namespace using `::fmt`
The nvcc compiler (at least up to 9.2) defines `__SIZEOF_INT128__`, but doesn't support 128-bit integers on device code:
```
error: "fmt::v6::format_arg_store<fmt::v6::basic_format_context<std::back_insert_iterator<fmt::v6::internal::buffer<char>>, char>, const char *, int, const char *>" contains a 128-bit integer, which is not supported in device code
```
The `std::is_base_of<T,U>()` and `std::is_reference<T>()` member functions were added in C++14. To maintain C++11 compatibility, use the `::value` instead.
Current code fails on intel-17 and other compilers if using strict C++11
The intel-17 and intel-18 compilers seem to require that `u` be `const`:
```
/src/fmt/format.h(226): warning #437: reference to local variable of enclosing function is not allowed
char data[sizeof(u)];
```
If `u` is declared as `const auto u =1u` instead of just `auto u=1u`, the file compiles with no warnings.
