libthread: fix ARM build by renaming file
Fixes #363 Change-Id: Ic8ad5ccce3935fdf00732d78d3024b535db90447
devdraw: fix `cmd-r` to toggle retina vs. non-retina mode on macOS (#361)
and not unexpectedly quitting an application. Fixes #360
acme: report close failure in Put, this time for sure
Missed in 0b349f6f that Bterm is not closing fd.
libthread: rm OpenBSD tas implementations
OpenBSD is using pthreads now, so no need for tas.
libthread: use consistent stack calculation code in makecontext
Also reduce duplication: makecontext is per-arch not per-os-arch. May fix #353.
libthread: rm NetBSD pthread reference in sysofiles.sh
It may be that pthreads on NetBSD is now good enough, but the build as written (introduced in 23a2368 at my suggestion) is certainly broken, since both NetBSD.c and pthread.c define the same functions. If NetBSD does support pthreads now, then a few things should happen together: - libthread/sysofiles.sh should drop its top NetBSD case entirely - libthread/NetBSD.c should be deleted - libthread/NetBSD-*-asm.s should be deleted - include/u.h's NetBSD case should define PLAN9PORT_USING_PTHREADS and #include <pthread.h> For now, restore to less clearly broken build.
all: remove Linux 2.4 vs 2.6 detection
Linux 2.4 is dead. (The libthread code hasn't worked for Linux 2.4 for a long time.)
libthread: remove Linux 2.4 code
Linux.c was for Linux 2.4 and is no longer used directly, only indirectly because NetBSD.c was a 1-line file #including Linux.c. So mv Linux.c NetBSD.c. Also rm Linux-*-asm.s which was for Linux 2.4 as well.
libthread: rm unused sparc-ucontext.h
More dead code.
libthread: rm Darwin pre-11.0.0 support
Darwin 11.0.0 was Mac OS X 10.7.0 aka Lion. The previous version was Snow Leopard, which has been unsupported by Apple since February 2014.
libthread: rm FreeBSD 4 code
Pretty sure FreeBSD 4 is gone now. :-)
