We weren't terribly consistent about whether to call Apple's OS "OS X"
or "Mac OS X", and the former is probably confusing to people who aren't
Apple users. Now that Apple has rebranded it "macOS", follow their lead
to establish a consistent naming pattern. Also, avoid the use of the
ancient project name "Darwin", except as the port code name which does not
seem desirable to change. (In short, this patch touches documentation and
comments, but no actual code.)
I didn't touch contrib/start-scripts/osx/, either. I suspect those are
obsolete and due for a rewrite, anyway.
I dithered about whether to apply this edit to old release notes, but
those were responsible for quite a lot of the inconsistencies, so I ended
up changing them too. Anyway, Apple's being ahistorical about this,
so why shouldn't we be?
since Apple shipped a compiler that needed this switch, and there's
increasing interest in using other compilers that won't accept the switch
at all. Better to let anybody who still needs the switch inject it via
CPPFLAGS. Per gripe from Neil Conway.
and up), per Chris Marcellino. This avoids consuming O(N^2) file
descriptors to support N backends. Tests suggest it's about a wash for
small installations, but large ones would have a problem.
-D_REENTRANT -D_THREAD_SAFE -D_POSIX_PTHREAD_SEMANTICS
for all ports. It can't hurt if they are not supported, but it makes
our job easier for porting.
Should fix Darwin compile and other platforms without mucking with the
thread detection code.
Allow additional thread flags to be added via port templates.
Change thread flag names to PTHREAD_CFLAGS and PTHREAD_LIBS to match new
configure script.
(it rejects some system header files...). Use -no-cpp-precomp instead.
I think it is okay to change this unconditionally, but if we hear
complaints from people still using very old compilers on Darwin,
we could put in a test to see which switch the compiler likes.
As proof of concept, provide an alternate implementation based on POSIX
semaphores. Also push the SysV shared-memory implementation into a
separate file so that it can be replaced conveniently.
Bruce Hartzler <bruceh@mail.utexas.edu>. It contains shared library
support, regression test map, and the usual template files. The dynamic
loader is missing, the spin lock code apparently doesn't assemble due to
syntax problems, and semaphores are to be hoped for from Apple.
