Fix NULL-free bug in hibernate on debug emulator
Fix several bugs related to hibernate/3 and HiPE

* sverker/valgrind-new-suppressions:
Make halfword emulator with valgrind target allocate low memory
Add erts_alloc_permanent_cache_aligned to supress valgrind
|
|
* rickard/scheduler-wait/OTP-9105:
The emulator could get into a state where it didn't check for I/O.
|
|
Limit ERTS_MSEG_FAKE_SEGMENTS (that is otherwise set for valgrind
target) to not apply to low memory needed by halfword emulator. This
will reduce the fault detection capability of valgrind for low memory.
Also correct a bug in the initial mmap and make sure the returned
memory region does not reach into high memory.

* sverker/clarify_nif_resource_doc:
clarify NIF resource object deallocation documentation
|
|
In the erl_nif documentation, clarify how and when NIF resource
objects can be deallocated. Specifically, add focus for the case of
calling enif_release_resource immediately after obtaining a resource
term from enif_make_resource, since this is likely to be a common
approach NIFs use to manage resources.
Also fix a couple misspellings in the erl_nif documentation.

* bjorn/erts/fix-fun-call/OTP-9095:
erts: Initialize register that may be referenced by garbage collection

* ks/process_status:

OTP-9102

The call_fun() function in the BEAM emulator is supposed to
to put the fun term in the x register following the actual arguments
and environment for the fun. But if the fun is not loaded and
a call to the error_handler:undefined_lambda/3 function is set up,
the x(3) register will not be initialized.
The lack of initialization is very unlikely to cause a problem
in practice, because all of the following things must happen:
1) An unloaded fun must be called (i.e. the fun must have
been received from another node or from a file or dets table).
2) The process must be scheduled out before the call to the
error_handler:undefined_lambda/3 function can take place.
3) The process must be garbage collected before the process
is scheduled in.
4) The x(3) register must contain a stale cons or box pointer
that happens to point into the the heap of the currently
executing process. (Because of the literal pool, the GC will
never copy anything that is outside of the heap.)
I was not able to write a test case that would force an
emulator crash.

Fixing miscellaneous "things" "detected" by dialyzer.
Also updated end date for a number of erts files.

Ease the valgrind supression of memory that are permanently
allocated and then aligned up to cache line.

|
* lukas/stdlib/native_escript/OTP-9076:
Update escrips to allow the -n or -compile(native) flag, which compiles the code within the escript with the +native flag. You need an HiPE enabled emulator for this to work.

Send warning instead of abort on EBUSY from pthread_mutex_destroy
|
|
Due to a bug in glibc the runtime system could abort
while trying to destroy a mutex. The runtime system
will now issue a warning instead of aborting.

BEAM loader: Add an assertion to check for overflowed code space
beam_emu: Eliminate redundant #ifdef
beam_emu: Remove unnecessary decrement of I in "case_end r"

|
While at it, clean up indentation of CHKBLK() macros.
|
|
The halfword emulator used to require special handling,
but no longer does.
|
|
It is not necessary to decrement I, because an exception is
about to be generated. Furthermore, I pointing *before* the
instruction that caused the exception may cause problems in
the future.

epoll on Linux has been seen to sometimes trigger unexpected
events. Most of the time these events are filtered by erl_check_io,
but may slip up to the driver in cases when fd's are reused.
Also made clear in driver docs that spurious events may happen.

Per H @ Tail-f: The original code here had problems that possibly
only occur if you abuse it for non-INET sockets, but anyway:
a) If the getsockopt for SO_PRIORITY or IP_TOS failed, the actual
requested setsockopt was never even attempted.
b) If {get,set}sockopt for one of IP_TOS and SO_PRIORITY failed,
but ditto for the other worked and that was actually the requested
option, failure was still reported to erlang.
