2018-02-13Fix size of fmt_double()'s format_str[] bufferMikael Pettersson
fmt_double() may write up to 8 characters into its format_str[] buffer, which however only has room for 7 characters. This case could be triggered by a call to erts_printf_format() with any floating-point format that also includes #, and + or a space, which may be uncommon, but a nif or driver could issue it.

2018-02-12erts: Add system_flags(erts_alloc,"+M?sbct *")Sverker Eriksson
to change sbct limit in runtime for chosen allocator type. With great power comes great responsibility.
2018-02-12erts: Add age order first fit allocator strategiesSverker Eriksson
ageffcaoff: Age First Fit Carrier, Address Order First Fit (within carrier) ageffcbf : Age First Fit Carrier, Best Fit (within carrier) ageffcaobf: Age First Fit Carrier, Address Order Best Fit (within carrier) Prefer old carriers, the older the better.
2018-02-08erts: Refactor erl_ao_firstfit_allocSverker Eriksson
In preparation for carrier age order. Change 'flavor' to 'blk_order' and 'crr_order'.

Fix rounding bug in float_to_list/2
2018-01-17Fix slow hipe executionSverker Eriksson
particularly slow erlc when compiler is hipe compiled. hipe_unified_loader:load did not patch external call sites and instead caused a double hipe mode switch per call. hipe_unified_loader:load is only used for early modules first loaded as beam and by code:atomic_load and friends.

2018-01-15erts: Refactor and cleanup sys_double_to_chars_fastSverker Eriksson
Replace long long with Uint64
2018-01-15erts: Fix float_to_list(F, [{decimals,D}]).Sverker Eriksson
Example symptom: 1> float_to_list(0.145, [{decimals,1}]). "0.2" There were two problems in sys_double_to_chars_fast 1. Most serious was adding 0.55555555 / (10^D) instead of 0.5 / (10^D) which imposed a 5.5% risk of a faulty rounding up. 2. Using fixpoint for frac_part which lost significant bits if F < 0.5
2018-01-15erts: Fix buffer overflow bug in erts_printf %fSverker Eriksson
Sign character was not accounted for. Ex: float_to_list(-3.1265538967899625e+69, [{decimals,16}]).

2018-01-03Fail if ':' is passed to binary_to_integer/2Frank Hunleth
Before: 1> binary_to_integer(<<":">>, 16). 3 After: 1> binary_to_integer(<<":">>, 16). ** exception error: bad argument in function binary_to_integer/2 called as binary_to_integer(<<":">>,16) Prior to this change, both list_to_integer/2 and binary_to_integer/2 would convert strings with values between ASCII '9' up to '0'+base for base > 10. For example, when converting in base 16, you could pass ':', ';', '<', '=', '>', and '?' without getting an exception. This was due to a missing check in c2int_is_invalid_char(). This change adds the missing check and a regression test for passing ':'. It also simplifies the code and tightens up an out-of-bounds check to make it off-by-one rather than off-by-two.

similar to the ones in OTP-19.2.3.1
2017-12-20erts: Fix alloc_SUITE:migrationSverker Eriksson
It crashed due to recursive calls to alloc_util in carrier initialization test callback.
2017-12-20erts: Improve carrier pool searchSverker Eriksson
* Give back carrier to owner when put in pool with use of dd-queue. * Replace pooled_list with pooled_tree for more efficient search of all owned pooled carriers. * Remove traitor_list as it does not serve much purpose anymore. * Add HOMECOMING bit flag in crr->allctr atomic to (1) avoid double enqueue into dd-enqueue. (2) trigger read barrier in get_used_allctr for newly received carriers.
2017-12-20erts: Improve alloc_SUITE:migrationSverker Eriksson
to mix it up with some realloc calls.
2017-12-20erts: Refactor carrier dealloc migrationSverker Eriksson
by adding a dedicated 'homecoming_dd_block' to use in dd-queue. + Preparation for dd-queue-migration of non-empty carriers. + Get rid of ugly hack where blk->carrier pointer is overwritten by dd-queue and then have to be restored.
