2016-10-21hipe,llvm: Change inc_stack_0 bif call to not_remoteSverker Eriksson
Seems to work either way, it just seem more correct as all other 'bif' calls are 'not_remote'.

Conflicts: erts/emulator/beam/beam_bif_load.c erts/emulator/beam/beam_load.c and added macro DBG_TRACE_MFA_P in beam_load.h
2016-10-14hipe: TRY fix llvm external calls to own moduleSverker Eriksson
to not be transformed to local calls. code_SUITE:uprade still fails if run with compile option {hipe,to_llvm}
2016-10-14hipe,erts: Remove cached fun 'native_address'Sverker Eriksson
Did not work with purge and made worse by new purge strategy. Did yield terrible performance when fun thing is created *before* fun code is loaded. Like when receiving not yet loaded fun from other node. The cached 'native_address' in ErlFunThing will not be updated leading to mode switch and error_handler being called for every call to the fun from native code.
2016-10-14erts: Fix early hipe patch loadingSverker Eriksson
by introducing hipe_bifs:commit_patch_load/1 that creates the HipeModule.
2016-10-14erts: Move new hipe ref and sdesc lists to loader stateSverker Eriksson
2016-10-14Add a loader state for HiPE code loadingMagnus Lång
Just like the BEAM loader state (as returned by erlang:prepare_loading/2), the HiPE loader state is contained in a magic binary. Eventually, we will separate HiPE loading into a prepare and a finalise phase, like the BEAM loader, where the prepare phase will be implemented by hipe_unified_loader and the finalise phase be implemented in C by hipe_load.c and beam_load.c, making prepare side-effect free and finalise atomic. The finalise phase will be exposed through the erlang:finish_loading/1 API, just like the BEAM loader, as this will allow HiPE and BEAM modules to be mixed in the same atomic "commit". The usage of a loader state makes it easier to keep track of all resources allocated during loading, and will not only make it easy to prevent leaks when hipe_unified_loader crashes, but also paves the way for proper, leak-free, unloading of HiPE modules.

and hipe_bifs:update_code_size
2016-10-10erts: Improve hipe load/upgrade/purge machinerySverker Eriksson
A step toward better integration of hipe load and purge Highlights: * code_server no longer needs to call hipe_unified_loader:post_beam_load/1 Instead new internal function hipe_redirect_to_module() is called by loading BIFs to patch native call sites if needed. * hipe_purge_module() is called by erts_internal:purge_module/2 to purge any native code. * struct hipe_mfa_info redesigned and only used for exported functions that are called from or implemented by native code. A list of native call sites (struct hipe_ref) are kept for each hipe_mfa_info. * struct hipe_sdesc used by hipe_find_mfa_from_ra() to build native stack traces.
2016-10-06dialyzer: Fix opaque bugHans Bolinder
The "decoration" of opaque types works better than before when opaque types are used by other opaque types.
2016-10-06dialyzer: Fix opaque bugsHans Bolinder
t_from_form() sometimes returned a more general type than it should have done due to a bug in from_form_loop(): it stopped when the limit was exceeded, which could mean a collapsed type. Returning a type with smaller depth should fix this. is_specialization() now handles opaque types before unions, which should fix another problem. The bugs reported by Kostis.

2016-09-07erl_bif_types: Properly unopaque maps:merge/2 argsMagnus Lång
erl_bif_types:type/5 was calling erl_types:map_pairwise_merge/3 directly with its (potentially opaque) arguments, causing Dialyzer crashes. Bug (ERL-249) reported and minimised test case provided by Felipe Ripoll.

2016-09-05hipe: Refactor ra callbacks to accept context argMagnus Lång
This allows us to pass around the context data that hipe_regalloc_prepass needs cleanly, without using process dictionary or parameterised modules (like it was previous to this change).
2016-09-05hipe: Reuse liveness between regalloc iterationsMagnus Lång
This is sound because the liveness data structure only stores liveness info at basic block boundaries, and the rewrites that happen in TargetSpecific:check_and_rewrite/2 preserves all existing definitions and uses, and all new liveness intervals, belonging to newly introduced temporaries, are always local to a basic block, and thus do not show up in the liveout or livein sets for the basic block.
2016-09-05hipe: Fix erl_types opaque match orderBjörn-Egil Dahlberg
2016-09-05hipe: Add ra_partitioned to o1 and upMagnus Lång
ra_partitioned significantly speeds up register allocation of larger functions without affecting allocation quality negatively. This is the final change needed to make o1 suitable for compiling really large functions without choking.
2016-09-05hipe_regalloc_prepass: Change splitting heuristicMagnus Lång
The division into an initial pass that may introduce temps, and following passes that must not forces us to make the same heuristic decision during each of these passes. Thus, the splitting heuristic can't be based on the number of temporaries -- at least without excluding temporaries above SpillLimit.
2016-09-05Implement the new ceil/1 and floor/1 guard BIFsBjörn Gustavsson
Implement as ceil/1 and floor/1 as new guard BIFs (essentially part of Erlang language). They are guard BIFs because trunc/1 is a guard BIF. It would be strange to have trunc/1 as a part of the language, but not ceil/1 and floor/1.
2016-09-02hipe: Make sure prepass temps are below SpillLimitMagnus Lång
If temps introduced by hipe_regalloc_prepass end up above SpillLimit, the register allocators will not spill them. This constraint is unnecessarily limiting the allocators and might theoretically lead to unallocatable programs (more temps above SpillLimit alive at a time than there are physical registers).
2016-09-02hipe_regalloc_prepass: Rename coloring collisionsMagnus Lång
2016-09-02hipe_ppc: 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_ppc_subst, was introduced to the ppc backend.
2016-09-02hipe_sparc: 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_sparc_subst, was introduced to the sparc backend.
2016-09-02hipe_arm: 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_arm_subst, was introduced to the arm backend.
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.
2016-09-02Simplify hipe_x86_ra_finalise:conv_ra_maplet/3Magnus Lång
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 IG partitioning to hipe_regalloc_prepassMagnus Lång
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.
