2016-07-11erts: After a call to a tracer nif, reset htopLukas Larsson
This is needed in order for the heap to never contain any pointers to invalid memory. This is good for performance and debugging reasons.

2016-07-08erts: Check if return_to trace is enabled for bifLukas Larsson
We have to do an extra check if the return_to trace is enabled here as it may have been cleared by the bif after the flags where created by the call_trace.

2016-07-01erts: Improve error printouts in erl_child_setupLukas Larsson
Add prints to stderr with a small description of the error so that errors will be easier to debug. Also if a protocol error is detected, erl_child_setup will abort instead of exit.
2016-06-30hipe: Fix bug in trap frame allocation wrappersMagnus Lång
The trap frame allocation wrappers occasionally call the garbage collector, even though built-in functions are not supposed to. On non-{x86,amd64} platforms, HiPE was optimising the BIF wrapper interface on the basis that BIFs do not GC. So, when hipe_reserve_beam_trap_frame called the garbage collector, the state in the PCB was stale and corruption happened. Now, these particular BIFs are reclassified as GC BIFs. Unfortunately, in order to do that we needed to introduce a gc_bif_interface_3 macro in every hipe_$ARCH_bifs.m4 file.
2016-06-30hipe: Add assertion for gc in bif without wrapperMagnus Lång
An easy source of tricky bugs is to start calling the garbage collector from a built-in function without adding that bif to hipe_bif_list.m4. With this change we, in the debug build, keep track of whether the canonical stack and heap pointers are stored in the PCB or in registers/stack, allowing us to catch this class of mistakes with an assertion.

2016-06-20erts: Fix spawn driver when env size is above pipe capacitySverker Eriksson
Symptom: open_port() succeeds, port program never starts but instead seem to terminate with exit_status 150 (EINVAL+128). When: If the command payload buffer (including the entire environment) for the port program is between 1 to 4 bytes above the pipe capacity, which is 65536 bytes on newer Linux, but can be as low as 4096 on older 32-bit Linux. Since: OTP-19.0-rc1.

2016-06-15erts: Change local sysname for ETS compressedSverker Eriksson
Yes this is an ugly workaround. One approach for a better solution could be to introduce an internal secret atom tagged as an atom with a unique index, but impossible to find by string hash lookup/insert.

2016-06-14erts: Increase bif and nif call_time trace testLukas Larsson
This makes the time that the tests execute longer, which means that on systems with low resolution on timers (e.g. windows) the test is less likely to fail.
2016-06-14erts: Fix distribution_SUITE:bulk_send_bigbig on windowsLukas Larsson
The granualarity of the windows time sometimes makes timer:tc return 0 as the time taken for the test. Change this to use the most common time instead.
