2016-03-29erts: Fix bug in enif_sendSverker Eriksson
Let cache_env() set env->heap_frag to same as MBUF(p) as it is in any other case.

2016-03-29erts: Fix bug in enif_term_to_binarySverker Eriksson
Wait until after dec_term and factory_close to do cache_env(), otherwise we will cache the wrong state.

* lukas/erts/inline_tagvaldef/OTP-13440: erts: inline tag_val_def
2016-03-29erts: inline tag_val_defLukas Larsson
The tag_val_def function was called and multiple switch statements had to be traversed in term.c, and then a big switch in the calling code to branch on the term types. By inlining the switches are merged by the compiler and a lot fewer branches have to be taken. Benchmarks show that this increases performance of enc_term by as much as 10%.

2016-03-16Take out (parts of) broken fp exception support for MacOS XBjörn Gustavsson
Floating-point exception support on MacOS X has never been especially reliable, and has therefore been disabled by default for a long time. The fpe support is now broken. Therefore, take out the unnecessary test for modern mcontext in configure (whatever that means) and the associated code in sys_float.c. Add #error directives to sys_float.c to make it clear that fpe is not supported. It seems to risky to mess with the mess of #ifdef's, so we will not attempt to remove all fpe support code for MacOS X.

2016-03-15erts: Use fcntl(fd, F_FULLFSYNC) instead of fdatasync on Mac OSXBjörn-Egil Dahlberg
The syscall fdatasync does not work as intended on Mac OSX. Both the function fsync and fdatasync now uses fcntl(fd, F_FULLFSYNC) on Mac OSX.

* rickard/ds-sched-suspend: Improved scheduler suspend functionality
2016-03-10Improved scheduler suspend functionalityRickard Green
- The calling process is now suspended while synchronizing scheduler suspends via erlang:system_flag(schedulers_online, _) and erlang:system_flag(multi_scheduling, _), instead of blocking the scheduler thread in the BIF call waiting for the operation to synchronize. Besides releasing the scheduler for other work (or immediate suspend) it also makes it possible to abort the operation by killing the process. - erlang:system_flag(schedulers_online, _) now only wait for normal schedulers to complete before it returns. This since it may take a very long time before all dirty schedulers suspends. - erlang:system_flag(multi_scheduling, block_normal|unblock_normal) which only operate on normal schedulers has been introduced. This since there are use cases where suspend of dirty schedulers are not of interest (hipe loader). - erlang:system_flag(multi_scheduling, block) still blocks all dirty schedulers as well as all normal schedulers except one since it is hard to redefine what multi scheduling block means. - The three operations: - changing amount of schedulers online - blocking/unblocking normal multi scheduling - blocking/unblocking full multi scheduling can now be done in parallel. This is important since otherwise a full multi scheduling block would potentially delay the other operations for a very long time.
