Commit 1eef765 introduced regression (conditional _always_ evaluates to true) in which erlang:localtime_to_universaltime/2 stopped working on systems configured with timezone without DST (i.e. UTC) on *BSD platforms: 1> erlang:localtime_to_universaltime({{2012,1,1},{0,0,0}}, true). ** exception error: bad argument Signed-off-by: Piotr Sikora <[email protected]>

* rickard/dealloc/OTP-10162: Improve the enqueue operation of delayed dealloc Implement delayed aux work wake up
2012-07-31Use static allocation of process lock queuesRickard Green
By using statically allocated lock queues there is no longer any need for locking corresponding pix lock when process locks have been transferred after a wait. This costs us 3 words extra in process structure, but improves performance during contention.
2012-07-31Improve the enqueue operation of delayed deallocRickard Green
The enqueue operation have been re-written to behave better during heavy contention by spreading writes over multiple locations. This enqueue operation also take advantage of the delayed aux work wake up functionality and can by this omit one memory barrier.
2012-07-31Implement delayed aux work wake upRickard Green
By using a delayed aux work wake up approach, a memory barrier can be omitted in the delayed dealloc enqueue operation. The amount of operations, on the potentially contended, wake up structure is also reduced.

* rickard/thr-prgr-use/OTP-10116: Fix faulty use of thread progress in handle_aux_work()
2012-06-18Fix faulty use of thread progress in handle_aux_work()Rickard Green
As an optimization old thread progress data was kept and used in handle_aux_work() in erl_process.c. This could cause memory to be deallocated at a later time than intended, which is quite harmless. This has, however, now been fixed.
2012-05-11DTrace bug in message-sendzheng siyao
dtrace doesn't print sender pid and receiver pid in message related probe correctly, it truncates pid string to 7 characters on 64bit platform(or 3 characters on 32bit platform). The dtrace related code did not set the string length correctly, it sets the string length to the length of a pointer rather than the buffer length.
2012-05-10Remove stale code for hybrid heap and incremental GCBjörn Gustavsson
The hybrid heap emulator was last working in the non-SMP R11B run-time system. When the constant pools were introduced in R12B, the hybrid heap emulator was not updated to handle them. At this point, the harm from reduced readability of the code is greater than any potential usefulness of keeping the code.

The fun names may look ugly, but if we clean them up we can't distinguish calls to the function defining the fun and to the fun itself.
