* mikpe/hipe-arm-interworking:
hipe: fix ARM/Thumb interworking
|
|
* dotsimon/sctp_paddrinfo_state:
Fix inet:getopts involving #sctp_paddrinfo{}
|

HiPE on ARM is currently severely broken if the rest of the VM is
compiled to run in Thumb mode -- calling native code quickly ends
up executing code in the wrong mode and crashing the VM. This is
a problem on e.g. Ubuntu which configures its system GCC to generate
Thumb by default. It can also be triggered by overriding CC or
CFLAGS when compiling the VM.
There were three issues that caused the breakage:
1. Assembly-coded functions in hipe_arm_glue.S weren't explicitly
tagged as functions, preventing the linker from generating the
correct mode-switching call instructions for calls from C to
these functions.
Fixed by tagging those symbols as functions.
2. A few BIF wrappers were so simple that they performed tailcalls
to the C BIFs. This fails to switch mode when C is in Thumb.
Fixed by performing ordinary recursive calls when C is in Thumb.
3. The assembly-coded source files weren't explicitly tagged as ARM.
Tested with the HiPE testsuite on ARMv7, with the VM built as ARM
and as Thumb. Also manually inspected the object code for the beam
executable and checked that call sites from C to HiPE's ARM runtime
code and vice versa used the correct mode-switching instructions.

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.

Handle peer addresses that are unconfirmed (i.e. in state SCTP_UNCONFIRMED).
Handle unknown states instead of using ASSERT

* lukas/erts/isfinite-fix/OTP-12268:
erts: Fix finite warning for clang
|
|
clang aka llvm claims to be __GNUC__ and thus we have to
explicitly check that it is not used.

|

This has to be done in order to consistently generate the same

erts: Add internal docs for super carrier and new cpool search.

erts: Fix bug causing mbc removed from cpool to be used at pool entrance

* lukas/erts/isfinite-fix/OTP-12268:
erts: Use finite instead of isfinite with gcc
|
|
Turns out that isfinite emits a function call and not
an instruction in gcc, this makes estone float arith
about 50-75% slower. finite emits the instruction so
we use that instead.

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.

* sverk/beam-ranges-bug/OTP-12273:
erts: Fix bug in beam_ranges
|
|
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.

* vinoski/erl-nif-init:
Fix missing field initializer in ERL_NIF_INIT macro
|
|
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
Erlang/OTP 17 [DEVELOPMENT] [erts-6.2] [source] [64-bit] [async-threads:10] [kernel-poll:false]

* sverk/hipe-wrap-bif-disable-gc-fixes/OTP-12231:

* rickard/maint-17/eager-check-io/OTP-12117:
No eager check I/O on OSE
Introduce support for eager check I/O scheduling
|
|
Symptom: base64_SUITE:roundtrip crashes with hipe compiled stdlib.
Problem: HIPE_WRAPPER_BIF_DISABLE_GC pushed a "trap frame", but the frame
was only popped if the call was recursive.
Solution: Only reserve "trap frame" if BIF call is recursive.
|
|
The trap_frame got pushed twice, first by the wrapper then by
hipe_push_beam_trap_frame as it was looking at F_DISABLE_GC.

Set IN_POOL flag _after_ mbc has been actually inserted.
Earlier it did not matter if IN_POOL was set early as it was not possible
to find a carrier before is was fully inserted. Now when searching
pooled_list and traitor_list we must make sure a found carrier has been
fully inserted into cpool before removing it.

* sverk/port_get_data-race/OTP-12208:
erts: Mend port_set_data with non-immed data for halfword VM
erts: Add test case for port_set_data and port_get_data
erts: Fix race between port_set_data, port_get_data and port termination
erts: Fix erlang:port_set_data/2 for non immediate data
|
|
Clear both IN_POOL and BUSY flags when empty carrier is removed
is removed from pool to be destroyed.
Earlier it was enough to leave BUSY flag set but now with pooled_list
we must clear IN_POOL to avoid using it as cpool_entrance in cpool_fetch().
|
|
|
|
The delayed dealloc queue destroyes one word but cpool_fetch() is expected
to return healthy carriers.
So we restore that overwritten word with a little bit of hackish code.
|
|
|
|
In the ERL_NIF_INIT macro, add a missing static initializer for the new
options field which was added to the ErlNifEntry struct for 17.3. This fix
prevents compile-time errors in NIFs when the compiler is instructed to
treat missing field initializers as errors.
|
|
|
|
Always update prt->data with atomic xchg-op.
Check for NULL data to detect racing port terminator.
Use NULL, as THE_NON_VALUE can be a valid pointer on debug VM.

hsize field was not set leading to VM crash
