2016-05-09Merge branch 'sverker/system_info-erts_mmap/OTP-13560'Sverker Eriksson
2016-05-09Merge branch 'sverker/trace-send-receive-matchspec/OTP-13507'Sverker Eriksson
2016-05-04erts: Add send and 'receive' to trace_info/2Sverker Eriksson
to obtain match specs
2016-05-04erts: Fix bug in trace_pattern for 'on_load'Sverker Eriksson
'on_load' is a call trace.
2016-05-04erts: Fix PAM to be callable from non-scheduler threadSverker Eriksson
also simplified the interface to to run PAM from trace
2016-05-04erts: Change receive matchspec to [NodeOrOther, Pid, Msg]Sverker Eriksson
2016-05-04erts: Add Sender in 'receive' trace matchspecSverker Eriksson
All 'EXIT' and monitor messages are sent from 'system' Timeouts are "sent" from 'clock_service'
2016-05-04erts: Add matchspec restrictions for 'receive' traceSverker Eriksson
and non-call-trace. This is the easy way out to avoid difficult locking scenarios when accessing tracing flags on another process.
2016-05-04erts: Add matchspec to 'receive' traceSverker Eriksson
2016-05-04erts: Remove multi scheduler blocking in match specsSverker Eriksson
for enable_trace and disable_trace operations. Instead seize needed locks while updating trace flags.
2016-05-04erts: Add match spec for send traceSverker Eriksson
2016-05-04erts: Rename constants in enum erts_break_opSverker Eriksson
with uppercase for constants and why not call them 'RESTART' and 'PAUSE' as the API.
2016-05-04erts: Beautify some code with container_of macroSverker Eriksson
2016-05-04erts: Add macro HAVE_ERTS_MMAPSverker Eriksson
and make erts_mmap unavailable at compile time if not supported.

* lemenkov/crash_dump_while_dist_error/PR-947/OTP-13474: Add patch to crash dump on large distribution
2016-05-04Reimplement -on_load()Björn Gustavsson
Load the module as old code; swap old and new code if the -on_load function succeeds. That way, a failed update attempt for a module that has an -on_load function will preserve the previous version of the code.

2016-05-02Refactor erts_finish_loading() and insert_new_code()Björn Gustavsson
As a preparation for fixing some issues with -on_load(), we will integrate insert_new_code() into erts_finish_loading. Also rename insert_new_code() to stub_insert_new_code() to make it clear that it will only be used when making a stub module

2016-04-29erl_process: Restore R18 HiPE PCB offsetsMagnus Lång
It was recently observed that the LLVM backend for HiPE was broken, generating code that crashes the VM. It turns out that this was caused by LLVM hard-coding an offset into the Erlang PCB, which became incorrect as of commit 3ac08f9b, that introduced a new member into the PCB before the HiPE-specific state, changing its offsets. For now, until a proper fix is implemented, we move this new member to after the HiPE-specific state, allowing the LLVM backend to work once more.

2016-04-25Print heap pointers for garbing processes during crashdumpSimon Cornish
In an SMP emulator, print_garb_info doesn't do anything because the heap pointers could be invalid. However, when crashdumping there are no schedulers running so it's ok to print this additional information which could be useful when examining a core file.
