2015-04-10Keep dirty schedulers from waking other schedulersSteve Vinoski
Prevent dirty schedulers from checking regular run queues and trying to wake up regular schedulers.

* sverk/maps-bin2term-eqhash-bug/12585: erts: Fix bug in map_from_list when keys clash in both value and hash erts: Fix bug in binary_to_term for big maps with 32 bit hash-clash

* sverk/ets-grow-faulty-assert/OTP-12647: erts: Fix ets bug in debug VM
2015-04-08erts: Fix ets bug in debug VMSverker Eriksson
Symptom: ASSERT(segtab[seg_ix] == NULL) in alloc_seg() fails. Remedy: Make sure we set segment pointer to NULL in free_seg() even when we switch to smaller segtab.
2015-04-08Merge branch 'sverk/valgrind-broken_halt'Sverker Eriksson
* sverk/valgrind-broken_halt: erts: Suppress valgrind for bif_SUITE:erlang_halt
2015-04-07erts: Fix bug in map_from_list when keys clash in both value and hashSverker Eriksson
Subtle bug in qsort callback. Cast from Sint to int does not retain sign.
2015-04-07erts: Fix bug in binary_to_term for big maps with 32 bit hash-clashSverker Eriksson
binary_to_term threw badarg as the "reject_dupkey" case in hashmap_from_unsored_array was always triggered when hash-clash was found as the first round in the loop compared the key with itself.
2015-04-01Merge branch 'egil/fix-maps-tmp-heap'Björn-Egil Dahlberg
* egil/fix-maps-tmp-heap: erts: Test deep Maps updates erts: Use halfword secure tmp heap erts: Remove unused tmp heap in make_internal_hash Conflicts: erts/emulator/test/map_SUITE.erl

2015-03-31erts: Fix size bug in maps:from_list/1 BIFBjörn-Egil Dahlberg
The wrong size was imprinted on maps with deep hash key collisions.
2015-03-31erts: Optimize insert and delete for big mapsSverker Eriksson
Do fast path without bit count for full internal nodes.
2015-03-30erts: Optimize == and /= for unequal big mapsSverker Eriksson
Bail out as soon as we find a diff between maps if we are not interested in term order.
2015-03-30erts: Refactor encode_size_struct_intSverker Eriksson
to handle the "start of list" case in one place and not seven. Note that this commit reverts (47d6fd3ccf35) back to using WSTACK and pushing raw pointers. We disable GC while yielding, so this should not be a problem.
2015-03-30erts: Suppress valgrind for bif_SUITE:erlang_haltSverker Eriksson
which does a deliberate deref of null pointer which is caught by a SEGV signal handler to resume crash dumping.
2015-03-30Merge branch 'egil/fix-maps-new_map-instruction'Björn-Egil Dahlberg
* egil/fix-maps-new_map-instruction: erts: Eliminate potential heap fragments after Map creation
2015-03-30Merge branch 'egil/fix-make_internal_hash-float'Björn-Egil Dahlberg
* egil/fix-make_internal_hash-float: erts: Add tests for internal_hash erts: Fix make_internal_hash for 0.0 vs -0.0
2015-03-27erts: Eliminate potential heap fragments after Map creationBjörn-Egil Dahlberg
2015-03-27erts: Fix make_internal_hash for 0.0 vs -0.0Björn-Egil Dahlberg
The internal_hash should produce the same hash value for identical terms, in this case 0.0 =:= -0.0.

Must save hamt_list in context.
2015-03-24erts: Fix comparison of exact termsBjörn-Egil Dahlberg
Comparison of exact terms could cause faulty term tests. This was caused by a faulty (too small) internal type. Symptom: -1 = erts_internal:cmp_term(2147483648,0). %% wrong Correct: 1 = erts_internal:cmp_term(2147483648,0). Reported-by: Jesper Louis Andersen
