This patch runs clang-format on all of libcxx/include and libcxx/src, in
accordance with the RFC discussed at [1]. Follow-up patches will format
the benchmarks, the test suite and remaining parts of the code. I'm
splitting this one into its own patch so the diff is a bit easier to
review.
This patch was generated with:
find libcxx/include libcxx/src -type f \
| grep -v 'module.modulemap.in' \
| grep -v 'CMakeLists.txt' \
| grep -v 'README.txt' \
| grep -v 'libcxx.imp' \
| grep -v '__config_site.in' \
| xargs clang-format -i
A Git merge driver is available in libcxx/utils/clang-format-merge-driver.sh
to help resolve merge and rebase issues across these formatting changes.

// The goal of this header is to provide mbstate_t without requiring all of
|
|
// <uchar.h> or <wchar.h>. It's also used by the libc++ versions of <uchar.h>
|
|
// and <wchar.h> to get mbstate_t when the C library doesn't provide <uchar.h>
|
|
// or <wchar.h>, hence the #include_next of those headers instead of #include.
|
|
// (e.g. if <wchar.h> isn't present in the C library, the libc++ <wchar.h>
|
|
// will include this header. This header needs to not turn around and cyclically
|
|
// include <wchar.h>, but fall through to <uchar.h>.)

// not define this for clang. This is also set in libc++'s <wchar.h> header,
|
|
// and we need to do so here too to avoid a different function signature given
|
|
// a different include order.
