2016-09-02hipe_x86: Add code rewrite RA callbacksMagnus Lång
These will not only be useful for hipe_regalloc_prepass, but also, after the introduction of a mk_move/2 (or similar) callback, for the purpose of range splitting. Since the substitution needed to case over all the instructions, a new module, hipe_x86_subst, was introduced to the x86 backend. Due to differences in the 'jtab' field of a #jmp_switch{} between x86 and amd64, it regrettably needed to be duplicated to hipe_amd64_subst.
2016-09-02hipe: Remove defun_to_cfg/1 RA callbackMagnus Lång
Now that all backends do register allocation on a CFG directly and define the defun_to_cfg/1 callback as the identity function, it can be removed.
2016-09-02Add new sanity assertion to hipe_regalloc_prepassMagnus Lång
As the just_as_good_as assertion was loosened with the `NowRegs >= CheckRegs` check, it no longer verified that hipe_regalloc_prepass had not incorrectly labeled a temp as unallocatable. We add that behaviour back.

2016-09-02hipe_x86: Simplify ra_postconditions is_mem_opndMagnus Lång
This is due to the improvements in hipe_temp_map, removing the need for duplicated logic in the backends.

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.

2016-09-01Remove 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.

The abstract_code chunk can also contain {eof,_}, {error,_}, and {warning,_} in addition to the abstract forms that make up the Erlang syntax proper.

2016-08-31Emacs: extend support for compile optionsJohan Claesson

2016-08-31dialyzer: Optimize an opaque type caseHans Bolinder
Fix a mistake in commit 85f6fe3b. Instead of using the declared opaque type, the form's type is used in a case where the opaque type is turned into a non-opaque type. The result is more general types (smaller Erlang terms) and faster analyses.
