2016-09-02hipe: Add hipe_regalloc_prepassMagnus Lång
hipe_regalloc_prepass speeds up register allocation by spilling any temp that is live over a call (which clobbers all register). In order to detect these, a new function was added to the target interface; defines_all_alloc/1, that takes an instruction and returns a boolean.

2016-09-02Fix overridden BIFsBjörn Gustavsson
The filters in a list comprehension can be guard expressions or an ordinary expressions. If a guard expression is used as a filter, an exception will basically mean the same as 'false': t() -> L = [{some_tag,42},an_atom], [X || X <- L, element(1, X) =:= some_tag] %% Returns [{some_tag,42}] On the other hand, if an ordinary expression is used as a filter, there will be an exception: my_element(N, T) -> element(N, T). t() -> L = [{some_tag,42},an_atom], [X || X <- L, my_element(1, X) =:= some_tag] %% Causes a 'badarg' exception when element(1, an_atom) is evaluated It has been allowed for several releases to override a BIF with a local function. Thus, if we define a function called element/2, it will be called instead of the BIF element/2 within the module. We must use the "erlang:" prefix to call the BIF. Therefore, the following code is expected to work the same way as in our second example above: -compile({no_auto_import,[element/2]}). element(N, T) -> erlang:element(N, T). t() -> L = [{some_tag,42},an_atom], [X || X <- L, element(1, X) =:= some_tag]. %% Causes a 'badarg' exception when element(1, an_atom) is evaluated But the compiler refuses to compile the code with the following diagnostic: call to local/imported function element/2 is illegal in guard
2016-09-02Don't crash when obsolete guard overrides local functionBjörn Gustavsson
The compiler would crash in v3_codegen when trying to compile the following code: is_port(_) -> false. foo(P) when port(P) -> ok. We *could* have the compiler interpret the code as: is_port(_) -> false. foo(P) when erlang:is_port(P) -> ok. But that would encourage using the obsolete form of the guard tests. Note that the following code is illegal: is_port(_) -> false. foo(P) when is_port(P) -> ok. It produces the following diagnostic: call to local/imported function is_port/1 is illegal in guard Therefore, we should refuse to compile the code.

2016-09-01Remove sys_pre_expandBjörn Gustavsson
The previous commits have made sys_pre_expand superfluous. Since sys_pre_expand is undocumented and unsupported it can be removed in a major release without prior deprecation. Also remove code in erl_parse that handles abstract code that has passed through sys_pre_expand. We considered deprecating sys_pre_expand just in case, but decided against it for the following reasons: - Anyone brave and knowledgeable enough to use sys_pre_expand should be able to cope with sys_pre_expand being removed. - If we kept it, but didn't test it anywhere in OTP, it could potentially stop working. So we would probably have to add some test cases.

2016-09-01compiler: Eliminate use of sys_pre_expandBjörn Gustavsson
sys_pre_expand previously did a lot more work, for example, translating records and funs, but now is merely a grab bag of small transformations. Move those transformations to v3_core.
2016-09-01shell_SUITE: Eliminate references to sys_pre_expand in commentsBjörn Gustavsson
Make it clear that we test that the shell is not dependent on the compiler application being in the path.
2016-09-01qlc_pt: Simplify code because of updated erl_expand_recordsBjörn Gustavsson
erl_expand_records now adds "erlang:" to calls to BIFs, so we can simplify the code.
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.
2016-09-01cover: Remove always stale commentBjörn Gustavsson
The comment in the catch-all clause in munge_expr/2 will always be stale. There is no way it can be kept up to date. For example, 'eof' is listed, but 'eof' is a top-level form and is actually handled in the catch-all clause for munge/4.
