2015-05-04erts: Use a lockable allocator on 'sys_write_buf'Björn-Egil Dahlberg
sys_write_buf allocator type is used from async-threads and needs to be lockable. In the SMP case the temporary allocator is lockable but not in the Non-SMP case. To remedy this the binary-allocator is used for the Non-SMP case, which is lockable.

2015-04-27erts: Specialize minus and plus instructionBjörn-Egil Dahlberg
Seen on SSL application where substraction with x registers were prevalent: * i_minus specialization on x registers * i_plus specialization on x registers
2015-04-27erts: Add move2 specialization for common move patternsBjörn-Egil Dahlberg
Common pattern seen in SSL: move y x | move r x -> move2 move r x | move y x -> move2 Common pattern seen in SSL and Compiler: move x r | move x x -> move2

May lessen load/store latency.
2015-04-23erts: Fix loader increment from minus instructionBjörn-Egil Dahlberg
A type error caused the optimization to never kick in.
2015-04-23erts: Add move window instructionBjörn-Egil Dahlberg
Move an entire region of x registers to the stack. This reduces the dispatch pressure of move instructions. Also introduce a move2 specialization for some common move patterns: move r y | move x y -> move2 : As above, moving regions to the stack move x r | move x y -> move2 : A seemingly common pattern

2015-04-22erts/hipe: unbreak arity 4 BIFsMikael Pettersson
This fixes arity 4 BIF support in HiPE, following its introduction on master (OTP 18) via the nox/ets-update_counter-4 merge. - define standard_bif_interface_4, nbif_4_gc_after_bif, and nbif_4_simple_exception on ARM: unbreaks the build on ARM - remove bogus stack re-alignment from standard_bif_interface_4 on AMD64: for 4-arg BIFs the stack is already aligned, and the code would misalign the C stack which violates the ABI and may cause alignment faults in vectorized code - the nbif_4_simple_exception OPD name on PPC64 was incorrectly using the nbif_3_simple_exception OPD name: this would have caused a multiple definition error in the assembler or linker In addition there are a few cleanups: - fix standard_bif_interface_N comment on x86 - fix standard_bif_interface_4 comment on SPARC - separate nbif_N_simple_exception blocks by empty lines on PPC, like on ARM, to clearly show which things belong together - fix standard_bif_interface_N comment on ARM - fix standard_bif_interface_4 on AMD64 to match the indentation and spacing conventions of the rest of that file

2015-04-21erts,hipe: Optimize away calls to emasculate_binarySverker Eriksson
Only call emasculate_binary if ProcBin.flags is set, which means it's a writable binary.

2015-04-20erts,hipe: Fix bug in binary matching of writable binarySverker Eriksson
Seen symptom: Hipe compiled code with <<C/utf8, ...>> = Bin does sometimes not match even though Bin contains a valid utf8 character. There might be other possible binary matching symptoms, as the problem is not utf8 specific. Problem: A writable binary was not "emasculated" when the matching started (as it should) by the hipe compiled code. Fix: Add a new primop emasculate_binary(Bin) that is called when a matchstate is created. ToDo: There are probably room for optimization. For example only call emasculate_binary if ProcBin.flags is set.
2015-04-20erts: Enable different abort signal from heartBjörn-Egil Dahlberg
By using environment variable HEART_KILL_SIGNAL, heart can now use a different signal to kill the old running Erlang. By default the signal is SIGKILL but SIGABRT may also be used by setting environment variable: HEART_KILL_SIGNAL=SIGABRT
