An FYI about C++ vintage coverage . . .
C++ headers missing in /usr/include/c++/v1/ (ignoring C++23 in-progress
material)
for:
# uname -apKU
FreeBSD CA72_16Gp_ZFS 14.0-CURRENT FreeBSD 14.0-CURRENT #25
main-n251456-22c4ab6cb015-dirty: Tue Dec 7 19:38:53 PST 2021
root@CA72_16Gp_ZFS:/usr/obj/BUILDs/main-CA72-nodbg-clang/usr/main-src/arm64.aarch64/sys/GENERIC-NODBG-CA72
arm64 aarch64 1400043 1400043
starting with C++ specific headers:
coroutine (C++20)
source_location (C++20)
memory_resource (C++17)
cuchar (C++11)
syncstream (C++20)
stop_token (C++20)
C compatibility headers (which C++23 looks to give the status: undeprecated)
( not analyzed for if covered via outside /usr/include/c++/v1/ )
assert.h
signal.h
stdarg.h
time.h
uchar.h
Others (empty/meaningless yet part of the standard):
ctgmath.h (actually: C++20 removed this one)
cstdalign (actually: C++20 removed this one)
iso646.h
stdalign.h
I ignore experimental/* status files.
I have not checked if any of these are missing from libc++
in a way not specific to FreeBSD: I just compared material
about the standard versions to the file names in
/usr/include/c++/v1/ .
