2014-09-04erts: Correct conversion of MIN_SMALL numeral to fixnumSverker Eriksson
list_to_integer and binary_to_integer returned un-normalized bignum for -134217728 on 32-bit and -576460752303423488 on 64-bit. Thanks to Jesper Louis Andersen, Mikael Pettersson and Anthony Ramine for report, initial patch and optimization suggestion.

2014-08-08erts: Fix neg int overflow when sint is min sizeLukas Larsson
When INT64_MIN is the value of a Sint64 we have to first cast it to an Uint64 before negating it. Otherwise we get an integer overflow which is undefined behaviour and in gcc 4.9 this results in -0 instead of -9223372036854775808 in gcc 4.8.

2014-08-05Fix abort of nosuspend-tasks in erts_port_task_schedule()Rickard Green
The counter for the amount of outstanding data in the port queue became inconsistent when aborting nosuspend-signals in erts_port_task_schedule(). This since the counter was subtracted by the data size of the signal although the data size had never been added to it. This inconsistency caused the port queue to remain in a busy state forever.

This fixes a bug introduced in f11aabdc9fec593c31e6c4f3fa25c1707e9c35df where filelib:eval_read_file_info/2 was made to use file:read_link_info/1 to never follow symlinks. This fixed wildcard/1 but broke every other function using eval_read_file_info/2. Reported-by: Louis-Philippe Gauthier Reported-by: Danil Zagoskin

2014-07-02Properly handle SINT_MIN in small_to_big()Anthony Ramine
As there is no overflow for signed integers, -SINT_MIN is undefined behaviour and the cast to unsigned needs to happen before negation. SINT_MIN denotes the minimum value that can be stored in the Sint type. beam/big.c:1512:6: runtime error: negation of -9223372036854775808 cannot be represented in type 'Sint' (aka 'long'); cast to an unsigned type to negate this value to itself

2014-06-13add_abstract_code: Remove 'from_asm' optionBjörn Gustavsson
The purpose of add_abstract_code is to give Dialyzer some abstract code so that it will not fail fatally when analysing prim_eval which was compiled from BEAM assembly. But if Dialyzer were to pass along the compiler options that the module was compiled with when translating the abstract code to Core Erlang, the 'from_asm' option would crash the compilation. Thus, since we are already cheating, we should cheat a little bit more and also remove the 'from_asm' option.
