2014-04-29erts: Remove some dead hipe specific codeSverker Eriksson
2014-04-29erts: Fix global tracing of beam function when called from hipe codeSverker Eriksson
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.
2014-04-29erts: Save some space in process struct for hipeSverker Eriksson
by combining hipe.ncallee and hipe.closure in a union as the comment indicate should be possible.
2014-04-29Fix race between ETS table deletion and unfixationSverker Eriksson
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.

2014-03-28prevent NIF purge during dirty NIF executionSteve Vinoski
Reference-count the NIF before and after invoking a NIF on dirty schedulers to prevent having the NIF purged during the call.
2014-03-28fix dirty NIF invalid memory readSteve Vinoski
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.

2014-03-27erts: Fix bug of scheduling a suspended processSverker Eriksson
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)));
2014-03-27erts: Adjust is_external_header() for new map tagSverker Eriksson

2014-03-26Change the subtag used for maps from 0xB to 0xFKostis Sagonas
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.

2014-03-26ose: Fix bug when hunting for signal proxyLukas Larsson
Sometimes the wrong signal, i.e. a read reply, would be received from this non-selective receive.
2014-03-26ose: Implement tcp inet driver for OSELukas Larsson
The inet driver for OSE has to handle signals instead of selects and thus the wrappers for ready_input/output are a little bit different. However the majority of the inet code remains the same.
