2014-01-22erts: Fix crash when comparing very large floats with integersSverker Eriksson
big_buf was one word too short on 32-bit emulators causing memory corruption. Seems like this did not cause a problem before the ESTACK memory layout was changed in 172ebf11dc455e22b87f.
2014-01-22erts: Refactor big-float compare on HALFWORD to use C-stackSverker Eriksson
for the temporary conversion from float to big. Preparation for coming bugfix of 'big_buf' array size.

2014-01-17erts: Refactor ESTACK & WSTACK to use a struct easy to "export"Sverker Eriksson
This is not a clean refactor. It changes the behaviour slightly of E/WSTACK_RESTORE. The allocated stack from E/WSTACK_SAVE is used as-is and not copied into default_stack. This will hopefully fix an illusive memory leak that valgrind is reporting.
2014-01-15fix system_flag deprecation warningsSteve Vinoski
Passing cpu_topology or scheduler_bind_type to erlang:system_flag/2 results in an error report warning that the argument is deprecated and is slated for removal in erts-5.10/OTP-R16. Since we're already past that version and no substitute approach has yet been decided for these features, keep the deprecation warning but bump the removal version it mentions up to Erlang 18.

2014-01-10erts: Remove the extra_root feature from the process structureSverker Eriksson
as we don't use it and instead have the feature to disable GC during trapping BIFs.
2014-01-10erts: Simplify term_to_binary by removing saved ESTACK from root setSverker Eriksson
We disabled GC (in 522a29666088d5) during trapping and don't need to include the saved ESTACK as part of root set.

2014-01-09erts: Increase gc tenure rateBjörn-Egil Dahlberg
The garbage collector tries to maintain the previous heap block size during a minor gc, i.e. 'need' is not utilized in determining the size of the new heap, instead it relies on tenure and garbage to be sufficiently large. In instances during intense growing with exlusively live data on the heap coupled with delayed tenure, fullsweeps would be triggered directly after a minor gc to make room for 'need' since the new heap would be full. To remedy this, the tenure of terms on the minor heap will always happen (if it is below the high watermark) instead of every other minor gc.

2014-01-08erts: Remove overestimation of heap space in binary_to_termSverker Eriksson
for 32-bit integers (INTEGER_EXT) on 64-bit architectures.
2014-01-07erts: Fix bs_get_integer instructionBjörn-Egil Dahlberg
The instruction bs_get_integer could unnecessarily trigger a garbage collection in failure cases which is unwanted or outright dangerous. Ex: <<X:Sz,_/bits>> = <<"some binary">> Previously, if Sz induced X to a bignum it would reserved memory size this on the heap via a garbage collection before checking if the size could actually match. It will now check the binary size before triggering a collection.

2013-12-02Fix erts_check_off_heap2 assertionAnthony Ramine
The test needs to be false to fail, not true. This was noticed with the following warning, where marking erl_assert_error as non-returning didn't help: beam/erl_gc.c:2772:2: warning: variable 'refc' is used uninitialized whenever switch default is taken [-Wsometimes-uninitialized] default: ^~~~~~~ beam/erl_gc.c:2775:26: note: uninitialized use occurs here ERTS_CHK_OFFHEAP_ASSERT(refc >= 1); ^~~~ beam/erl_gc.c:2738:11: note: expanded from macro 'ERTS_CHK_OFFHEAP_ASSERT' if (!(EXP)) \ ^ beam/erl_gc.c:2759:18: note: initialize the variable 'refc' to silence this warning erts_aint_t refc; ^ = 0
