* 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.

2012-05-11DTrace 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.

2012-05-04gen_tcp: Make setopts(S,[{active,once}]) try a readPatrik Nyblom
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.
