Make hipe to beam calls use export entry.
Makes it a lot easier to handle global tracing correctly
(breakpoints in export entry). A beam function should now be traced
correctly regardless how it is called.
This will also fix a SEGV crash when a hipe stub is made pointing into
a traced export entry and tracing is then stopped which clears the export
entry causing the hipe stub to execute beam instruction NULL.
This commit assumes that hipe code never calls local beam functions, which
should be the case nowadays as we only hipe compile entire modules.
|
|
by combining hipe.ncallee and hipe.closure in a union
as the comment indicate should be possible.

Symptom: VM crash running mnesia_SUITE
Scenario: Process A terminates while still having fixed table T
and process B "at the same time" deletes table T with ets:delete/1 or
by terminating.
Problem: A table scheduled for deallocation do only have a valid
'common' part. The unfix-table-at-process-exit code tried to read the
hash-specific part of such a table.
Solution: Must back off if DB_DELETE flag is set.
Since: R16B

as it times out on some machines.
Not much point in redoing with lower input reductions when the terms
are so big we will trap several times anyway.

Remove a superfluous echo in the emulator Makefile
|
|
Reference-count the NIF before and after invoking a NIF on dirty schedulers
to prevent having the NIF purged during the call.
|
|
Dirty NIF support used an Export structure to facilitate calls to dirty
NIFs and finalizers, but Export isn't large enough to hold all necessary
data. This was causing an invalid memory read in beam_emu.c past the end of
the Export object. Add a local extended Export struct to erl_nif.c that can
hold all the necessary data.

This is a race that can cause RUNNING (instead of RUNNING_SYS)
set on a SUSPENDED process. The effect of this race happening is probably
quite benign.
The bug was discovered by process_SUITE:processes_gc_trap on debug VM
crashing on last assert in schedule():
/* Never run a suspended process */
ASSERT(!(ERTS_PSFLG_SUSPENDED & erts_smp_atomic32_read_nob(&p->state)));

to not mistake a map for an external term (pid, port or ref).

The subtag chosen for maps breaks crucial assumptions in other parts of
the system, in particular the native code generation scheme used in the
HiPE compiler. Therefore it is better to use 'the other' unused subtag.
The main change here is the use of 0xF subtag for maps instead of 0xB.
The rest of the differences are changes to and additions of comments.
One more comment from my part.
I noticed that the file contains the following two lines:
The comment of the second line is most certainly a copy and paste error
and should be appropriately fixed by the OTP developers. More importantly,
it would be great if that subtag (0x7) turned out to be unused and could
be used for maps instead of the 0xF one. This might turn out very handy
in the future. I can elaborate on this, if needed.

as it fails with timeout sometimes.
