Bug ID: 38495
Summary: After r338419, <ctime> no longer compiles on FreeBSD,
due to lack of timespec_get()
Product: libc++
Version: 7.0
Hardware: PC
OS: FreeBSD
Status: NEW
Severity: release blocker
Priority: P
Component: All Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: dimi...@andric.com

While testing 7.0.0 rc1, we got 2028 new libc++ test failures, most of which
are due to errors similar to:

using ::timespec_get;
~~^~~~~~~~~~~~
timespec
/usr/include/sys/_timespec.h:44:8: note: 'timespec' declared here
struct timespec {
^
This is due to FreeBSD not having timespec_get(), even though it is apparently
required by C11, and the conditional in <ctime> being:
#if _LIBCPP_STD_VER > 14 && defined(_LIBCPP_HAS_C11_FEATURES)
using ::timespec_get;
#endif
Work is ongoing to add timespec_get() to FreeBSD, but for 7.0.0 a workaround
would be nice.
