2010-06-03Fix ops.tab to include i_return_time_traceBjörn-Egil Dahlberg
Without the instruction defined in ops the interpreter will not compile when using NO_JUMPTABLE.
2010-06-03Fix bp_hash_put to do hash value after rehashBjörn-Egil Dahlberg
If a rehash was done the old hash value was used. This was incorrect.
2010-06-03Fix assertion in trace_pattern for bifsBjörn-Egil Dahlberg
2010-06-03Teach erlang:system_info/1 to list snifsBjörn-Egil Dahlberg
erlang:system_info(snifs) lists all static native implemented functions. The function presents the lists with three tuple values containing MFAs [{Module, Function, Arity}, ...].
2010-06-03Teach call time trace patterns to include bifsBjörn-Egil Dahlberg
2010-06-03Fix BeamInstr code array in export.hBjörn-Egil Dahlberg
2010-06-03Teach call count tracing to use atomicsBjörn-Egil Dahlberg
Call count previously used a global lock for accessing and writing its counter in the breakpoint. This is now changed to atomics instead. The change will let call count tracing and cprof to scale better when increasing the number of schedulers.
2010-06-03Add a scheduler array for BpData at BeamInstr[-4]Björn-Egil Dahlberg
To solve the issue of multiple schedulers constantly updating the head pointer to the bp data wheel, each scheduler now has its own entrypoint to the wheel. This head pointer can be updated without a locking being taken. Previously there were no lock ...
2010-06-03Add search keys in breakpoints and a searchfunctionBjörn-Egil Dahlberg
2010-06-03Fix BeamInstr for call_timeBjörn-Egil Dahlberg
2010-06-03Teach call_time trace to use intruction pointersBjörn-Egil Dahlberg
call_time trace will use instruction pointers instead of breakpoint data pointers. More costly lookup but the bdt structure might be deallocated, we do not want that. Remove unnecessary pattern lock.
2010-06-03Add return_time trace and PSD deletionsBjörn-Egil Dahlberg
2010-06-03Remove trailing character in beam_bif_loadBjörn-Egil Dahlberg
2010-06-03Fix set_function_break to use correct breakpointBjörn-Egil Dahlberg
op_i_time_breakpoint is now used
2010-06-03Add processes hashes for call time breakpointsBjörn-Egil Dahlberg
Call time breakpoint tracing traces per call trace per process. - Add hashes to support the extra dimension. - Teach trace_info/2 to handle the extra information dimension.
2010-06-03Fix lock-checking for PSD call_time breakpointsBjörn-Egil Dahlberg
2010-06-03Call time breakpoint tracing frameworkBjörn-Egil Dahlberg
Initial commit with a new breakpoint instruction and PSD areas for temporary time storage during tracing.
2010-06-03OTP-8675 Fix erroneous return value from erlang:system_info(multi_scheduling)Rickard Green
erlang:system_info(multi_scheduling) sometimes erroneously returned enabled when it should have returned blocked.
2010-06-03OTP-8673 Adjust alignment of scheduler data and run queuesRickard Green
Alignment of scheduler data and run queues were adjusted.
2010-06-03OTP-8666 Enable automatic binding of schedulers when possibleRickard Green
The runtime system will by default bind schedulers to logical processors using the default_bind bind type if the amount of schedulers are at least equal to the amount of logical processors configured, binding of schedulers is supported, and a CPU topology is available at startup. NOTE: If the Erlang runtime system is the only operating system process that binds threads to logical processors, this improves the performance of the runtime system. However, if other operating system processes (as for example another Erlang runtime system) also bind threads to logical processors, there might be a performance penalty instead. If this is the case you, are are advised to unbind the schedulers using the <seealso marker="erl#+sbt">+sbtu</seealso> command line argument, or by invoking <seealso marker="erlang#system_flag_scheduler_bind_type">erlang:system_flag(schedule r_bind_type, unbound)</seealso>.
2010-06-03OTP-8555 Send message from NIFSverker Eriksson
New NIF features: Send messages from a NIF, or from thread created by NIF, to any local process (enif_send) Store terms between NIF calls (enif_alloc_env, enif_make_copy) Create binary terms with user defined memory management (enif_make_resource_binary)

* pan/unregister_error: Add possibly missing process lock before unregistering oneself Keep process lock over trace of unregister OTP-8663 Unregister may crash VM Extreme combinations of register/unregister in a highly parallell SMP application could crash the VM. The error is corrected.
2010-06-01OTP-8612 Fix potential premature destruction of port locksRickard Green
Port locks could be prematurely destroyed.
2010-06-01OTP-8658 Add missing memory barriers in erts_poll()Rickard Green
Missing memory barriers in erts_poll() could cause the runtime system to hang indefinitely.
2010-06-01Remove unsupported erlang:blocking_read_file/1Björn Gustavsson
This BIF was only used by the now broken SAE support.
2010-06-01Remove stray SAE supportBjörn Gustavsson
The experimental Standalone Erlang (SAE) support based on Joe Armstrong's work has long been broken. Remove the remaining code and Makefile rules.

Add new NIF API functions - enif_make_atom_len - enif_make_existing_atom_len - enif_make_string_len These are basically the same as enif_make_atom, enif_make_existing_atom and enif_make_string except that the new functions require a length parameter instead of a null-terminated C-string.

2010-05-20sys.h: Correct the get_int64() macroBjörn Gustavsson
The get_int64() macro has never been used (it was probably added for completeness at the same time that put_int64() was added), but it was not actually used and therefore it does not actually work.
2010-05-20Remove stray support for the put_literal/2 instructionBjörn Gustavsson
put_literal/2 was an experimental instruction added in R11 to support literals, but before the R12 release support for literals was implemented for all instruction, making the put_literal/2 instruction redundant. Although the beam_disasm module supports dissambley of instructions in older releases, there is no reason to have it support experimental instructions.
2010-05-20Remove the bs_bits_to_bytes/3 instructionBjörn Gustavsson
The last compiler to generate code that uses the bs_bits_to_bytes/3 instruction was the R11 compiler. Since we don't support loading R11 *.beam files in R14, removing the remaining support for the instruction.
2010-05-20erts: Stop supporting non-literal empty tuplesBjörn Gustavsson
Since R12B, empty tuples are literals. Thus the compiler will no longer generate the instruction: put_tuple 0 Destination for creating an empty tuple. It is now time to stop supporting that instruction in the run-time system. While we are at it, correct a typo.
