2016-09-05Add math:floor/1 and math:ceil/1Björn Gustavsson
Add math:floor/1 and math:ceil/1 to avoid unnecessary conversions in floating point expressions. That is, instead of having to write float(floor(X)) as part of a floating point expressions, we can write simply math:floor(X).

2016-09-01Teach erl_expand_records to translate module-less callsBjörn Gustavsson
As the next step in eliminating sys_pre_expand, teach erl_expand_records to handle calls without explicit module name. If such call refer to a BIF or imported function, add an explicit module name. That means that any subsequent pass will know that a call without a module name is always to a local function defined in the module.
2016-09-01erl_internal: Add add_predefined_functions/1Björn Gustavsson
The sys_pre_expand module used to do a lot more (translate records and funs, for example), but now it does very little. Most of the code is an identify transformation of the abstract format. The identity transformation part of the code must be maintained and kept correct when new forms are added to the abstract format. That adds to the maintance burden. It also adds (slightly) to compilation times. Therefore, we want to eliminate sys_pre_expand, moving all of its (non-identity) transformations to better places. As a preliminary first step, move the code that adds the pre-defined functions (such as module_info/0) to a new function in erl_internal.

2016-05-10erts: Implement max_heap_size process flagLukas Larsson
The max_heap_size process flag can be used to limit the growth of a process heap by killing it before it becomes too large to handle. It is possible to set the maximum using the `erl +hmax` option, `system_flag(max_heap_size, ...)`, `spawn_opt(Fun, [{max_heap_size, ...}])` and `process_flag(max_heap_size, ...)`. It is possible to configure the behaviour of the process when the maximum heap size is reached. The process may be sent an untrappable exit signal with reason kill and/or send an error_logger message with details on the process state. A new trace event called gc_max_heap_size is also triggered for the garbage_collection trace flag when the heap grows larger than the configured size. If kill and error_logger are disabled, it is still possible to see that the maximum has been reached by doing garbage collection tracing on the process. The heap size is defined as the sum of the heap memory that the process is currently using. This includes all generational heaps, the stack, any messages that are considered to be part of the heap and any extra memory the garbage collector may need during collection. In the current implementation this means that when a process is set using on_heap message queue data mode, the messages that are in the internal message queue are counted towards this value. For off_heap, only matched messages count towards the size of the heap. For mixed, it depends on race conditions within the VM whether a message is part of the heap or not. Below is an example run of the new behaviour: Eshell V8.0 (abort with ^G) 1> f(P),P = spawn_opt(fun() -> receive ok -> ok end end, [{max_heap_size, 512}]). <0.60.0> 2> erlang:trace(P, true, [garbage_collection, procs]). 1 3> [P ! lists:duplicate(M,M) || M <- lists:seq(1,15)],ok. ok 4> =ERROR REPORT==== 26-Apr-2016::16:25:10 === Process: <0.60.0> Context: maximum heap size reached Max heap size: 512 Total heap size: 723 Kill: true Error Logger: true GC Info: [{old_heap_block_size,0}, {heap_block_size,609}, {mbuf_size,145}, {recent_size,0}, {stack_size,9}, {old_heap_size,0}, {heap_size,211}, {bin_vheap_size,0}, {bin_vheap_block_size,46422}, {bin_old_vheap_size,0}, {bin_old_vheap_block_size,46422}] flush().
