* 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.

This commit introduces no functional change. It only adds comments and changes some function/variable names.
2012-07-09Fix erl_prim_loader errors in handling of primary archiveSiri Hansen
The following errors have been corrected: * If primary archive was named "xxx", then a file in the same directory named "xxxyyy" would be interpreted as a file named yyy inside the archive. * erl_prim_loader did not correctly create and normalize absolute paths for primary archive and files inside it, so unless given with exact same path files inside the archive would not be found. E.g. if escript was started as /full/path/to/xxx then "./xxx/file" would not be found since erl_prim_loader would try to match /full/path/to/xxx with /full/path/to/./xxx. Same problem with ../. * Depending on how the primary archive was built, erl_prim_loader:list_dir/1 would sometimes return an empty string inside the file list. This was a virtual element representing the top directory of the archive. This has been removed. Thanks to Tuncer Ayaz and Shunichi Shinohara for reporting and co-authoring corrections.
2012-07-06[erts,kernel,stdlib] fix escript/primary archive reloadingTuncer Ayaz
If the mtime of an escript/primary archive file changes after being added to the code path, correctly reload the archive and update the cache. The existing code didn't consider that it might be a zip archive and failed: =ERROR REPORT==== 3-Aug-2011::09:21:21 === File operation error: bad_central_directory. Target: /escript_archive/module.beam. Function: get_file. Process: code_server. Thanks David Reid and Hakan Mattson.

* sverk/hipe-arm-fix: hipe_arm.c: remove dead code Workaround gcc bug affecting ARM debug build Fix compile error of HIPE enabled DEBUG emulator for ARM Fix hipe bif calling bug on ARM Add armv7l and armv5tejl as a recognized ARM architectures OTP-10137
2012-06-25hipe_arm.c: remove dead codeMikael Pettersson
erts/emulator/hipe/hipe_arm.c started out as a clone of hipe_ppc.c, with #ifdefs to select ARM-specific code. Somehow those #ifdefs never got cleaned out, resulting in fairly ugly-looking code. This eliminates the #ifdefs, deletes dead PowerPC-specific code, and keeps only the ARM-specific code. I've verified that the exact same assembly code is generated for hipe_arm.c before and after this patch (if you compile without -g, with -g there are unavoidable changes to the debug data).

* 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.

2012-05-25erts: Make 64-bit installer look for MS Redistributable in the right placesRaimo Niskanen
The installer runs in 32-bit mode so 64-bit windows does not show it the system directories a 64-bit application will see. To find out if the MS C++ 2010 Redistributable Package is installed the installer for 64-bit Erlang must search for msvcr100.dll in: $WINDIR\sysnative\ $WINDIR\WinSxS\amd64*\ instead of for 32-bit Erlang $SYSDIR\ $WINDIR\WinSxS\x86*\ This patch also makes the installer if called in silent mode call the MS Redistributable installer in silent mode.

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.

This significantly reduces latency for tcp servers with high load, as we need not go into poll to get the next message. Maximum throughput may increase between 4 to 6 times compared to R15B.
