2010-06-07Let ei_get_type() return ERL_FLOAT_EXT instead of NEW_FLOAT_EXTBjörn-Egil Dahlberg
2010-06-07Fix ei_tmo to restrict dflags to NEW_FLOAT_EXTBjörn-Egil Dahlberg
Erl_Interface is updated to restrict distribution to NEW_FLOAT_EXT only. The testsuite ei_tmo is updated to reflect that.
2010-06-07compact IEEE 754 double encoding in external binary format for eiSteve Vinoski
Implement the compact IEEE 754 double encoding in external binary format for ei. Encoding for ei now always produces the NEW_FLOAT_EXT format. Decoding and term printing handle both the old ERL_FLOAT_EXT encoding and the new NEW_FLOAT_EXT encoding. Legacy erl_interface code also handles the new encoding, but still produces the ERL_FLOAT_EXT encoding by default. Also enable the DFLAG_NEW_FLOATS distribution flag. Reduce the number of copies of the code for encoding and decoding doubles throughout ei and erl_interface by instead calling the ei encoding and decoding functions wherever possible. Restore commented-out float tests in ei_decode_SUITE and ei_encode_SUITE in lib/erl_interface/test. Modify them to make them match the style of other tests in the same suites. These changes are based on an ei float patch from Serge Aleynikov originally submitted against R12B-2 in July 2008.
2010-06-07fix typo in ei_decode_ei_term documentationSteve Vinoski
Change "encoding" to "decoding" where the documentation describes the return value 0.
2010-06-07Fix confusing dialyzer warnings for is_record/2 with illegal recordsBjörn Gustavsson
In commit 1858cb81391d2bce29b4b7620574ca60128cebf7, erl_expand_records started to optimize is_record/2 in guards by replacing it with pattern matching (if possible). Unfortunately, dialyzer will no longer see the code before the optimization, so any warnings produced in code such as: case ExprNotProducingRecord#rec{} of X when is_record(X, rec, N) -> ... will refer to the optimized code and not the source code, which is confusing for the user. Introduce the no_is_record_optimization option for turning off the optimization and use it in dialyzer. Reported-by: Kostis Sagonas

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.

Documented call time breakpoints in - erlang:trace_pattern/3 - erlang:trace_info/2
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.

2010-06-03Teach 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 ...

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>.
