This refactor was done using the unifdef tool like this:
for file in $(find erts/ -name *.[ch]); do unifdef -t -f defile -o $file $file; done
where defile contained:
#define ERTS_SMP 1
#define USE_THREADS 1
#define DDLL_SMP 1
#define ERTS_HAVE_SMP_EMU 1
#define SMP 1
#define ERL_BITS_REENTRANT 1
#define ERTS_USE_ASYNC_READY_Q 1
#define FDBLOCK 1
#undef ERTS_POLL_NEED_ASYNC_INTERRUPT_SUPPORT
#define ERTS_POLL_ASYNC_INTERRUPT_SUPPORT 0
#define ERTS_POLL_USE_WAKEUP_PIPE 1
#define ERTS_POLL_USE_UPDATE_REQUESTS_QUEUE 1

* john/erts/runtime-lcnt:
Document rt_mask and add warnings about copy_save
Add an emulator test suite for lock counting
Break erts_debug:lock_counters/1 into separate BIFs
Allow toggling lock counting at runtime
Move lock flags to a common header
Enable register_SUITE for lcnt builds
Enable lcnt smoke test on all builds that have lcnt enabled
Make lock counter info independent of the locks being counted

The implementation is still hidden behind ERTS_ENABLE_LOCK_COUNT, and
all categories are still enabled by default, but the actual counting can be
toggled at will.
OTP-13170

|
If we don't have the main lock, multiple threads may come in and
do the flush at the same time which will lead to all kinds of
strang problems.
|
|
The relevant macros are already guarded by said #ifdefs.
|
|
You're not supposed to do this, but it behaved correctly even with a debug
build aside from degraded performance (The scheduler started to busy-wait
for new operations rather than sleep).

(First attempt to fix in 23f132d9ab776a.)
If an synchronous GC was requested by calling:
erlang:garbage_collect(Pid, [{async,Ref}])
the reply message could in certain circumstances be
lost.
The problem is that cleanup_sys_tasks() is never called
if there are dirty tasks, but no other active system tasks.
Also shorten the long waiting times in the test case
binary_SUITE:trapping/1 to make it much more likely that
the GC have not already finished when the process is killed.
|
|
Before terminating a process, add assertions to make sure that
all queues for system tasks have been emptied.

the reply message could in certain circumstances be
lost.
The problem is in cleanup_sys_tasks() in erl_process.c.
If there were at least one dirty task, only the first
dirty task would be cleaned up. All other systems tasks
would not be cleaned up (that is, no replies would be
sent to other processes waiting for the tasks to finish).

The previous code worked through luck because the memory
returned from erts_alloc was zero:ed and SCHED_NORMAL
is 0. But if you run with +Meamin that is not always the
case which is how this error was detected.
