Use the new 64-bit atomic ops API
Introduce a 64-bit atomic ops API
|
|
|
|
The 64-bit atomic ops API is implemented by
* native word size atomic ops on 64-bit architectures, and
* native double word size atomic ops on 32-bit architectures
when available. When native double word size atomic is not
available, the fallback using modification counters is
used.

For searching a key in an array we use linear search in arrays
up to 10 elements.
Selecting on tuple arity will always use linear search.
Instead of using two different instructions we assume selecting on
different tuple arities are always few in numbers.

Ensure that the return value from a dirty NIF call is made part of the GC
rootset. Add a new regression test to nif_SUITE.
Thanks to Daniel Goertzen for reporting the error and providing a test
case, and to Sverker Eriksson for making test case reproducible and finding
the fix.

This patch allows checking for NIF API version in a way similar to
driver version. E.g. by calling erlang:system_info(nif_version).

Symptom: VM on OSX (darwin11.4.2) with +Meamin running sasl tests,
crashing when init:reboot() does erlang:purge_module(installer).
Problem: Off-by-one bug in beam_ranges:find_range, returning the wrong
range if the 'end' of one module is the 'start' of the next. This is only
possible if using sys_alloc (+Meamin) as our own allocators always put
block headers between allocated payload data.

OS X Mavericks builds result in a number of warnings about finite() being
deprecated, like these:
beam/erl_arith.c:451:7: warning: 'finite' is deprecated: first deprecated in OS X 10.9 [-Wdeprecated-declarations]
ERTS_FP_ERROR(p, f1.fd, goto badarith);
^
sys/unix/erl_unix_sys.h:319:33: note: expanded from macro 'ERTS_FP_ERROR'
^
sys/unix/erl_unix_sys.h:244:51: note: expanded from macro '__ERTS_FP_ERROR'
^
/usr/include/math.h:718:12: note: 'finite' has been explicitly marked deprecated here
extern int finite(double) __OSX_AVAILABLE_BUT_DEPRECATED(__MAC_10_0, __MAC_10_9, __IPHONE_NA, __IPHONE_NA);
Add checks to use isfinite() instead of finite() where available. Verified
on OS X Mavericks 10.9.5 and Ubuntu 12.04.

Running "erl -smp disable" on an emulator built with dirty scheduler
support caused problems such as segmentation violations and emulator status
line outputs containing garbage. For example:
$ erl -smp disable
Segmentation fault (core dumped)
and:
$ erl -smp disable
Erlang/OTP 17 [DEVELOPMENT] [erts-6.2] [source] [64-bit] [ds:10:4297895689:4299948152] [async-threads:280]
This problem also caused the emulator smoke_test_SUITE to hit these same
problems if run in an emulator started with the "-smp disable" option.
Fix this segmentation violation by ensuring that dirty scheduler
information is printed in the status line only when the emulator is
compiled with ERTS_SMP enabled.
With this fix in place, the smoke_test_SUITE now passes when the "-smp
disable" option is used, and the emulator status line prints correctly for
both "-smp enable" and "-smp disable":
$ erl -smp enable
Erlang/OTP 17 [DEVELOPMENT] [erts-6.2] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:10] [kernel-poll:false]
and:
$ erl -smp disable
