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

2018-01-03Fail 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.

2017-11-24Fix purging of modules with "fake literals"Björn Gustavsson
When compiling Erlang source code, the literal area for the module can only contain data types that have a literal syntax. However, it is possible to sneak in other data types (such as references) in the literal pool by compiling from abstract or assembly code. Those "fake literals" would work fine, but would crash the runtime system when the module containing the literals was purged. Although fake literals are not officially supported, the runtime should not crash when attempting to use them. Therefore, fix the garbage collection of literals and releasing of literal areas. https://bugs.erlang.org/browse/ERL-508

2017-10-09erts: Fix caller trace for apply bifsLukas Larsson
Bifs that are called through the export entry using i_call_last could have their cp set to return_trace, just like any other call. So we have to unwind the trace stack to get the correct cp. Not doing this creates a lot of issues for fprof.

2017-09-22Correctly append sub-binaries in iolist_to_iovecJohn Högberg
The byte_offset of sub-binaries wasn't taken into account for ProcBins, subtly ruining the results. The test suite didn't catch it since it didn't check for sub-binaries in particular, and only checked for equality between variations -- not whether the output was equal to the input.
