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.

* sverker/hipe-sparc-19/PR-1148: Eliminate catch-all clause from two functions Increase the time limit used by the test suite
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.
2016-08-26Eliminate catch-all clause from two functionsKostis Sagonas
A stronger version of Dialyzer complained that some case clauses in functions xaluop_is_shift/1 and xaluop_normalise/1 are unreachable. These clauses are now commented out. While at it, I thought that it would be better to eliminate the catch-all clauses in order to be certain we properly handle all RTL instructions that are used as inputs to these functions. Note: The code will now crash if there are unhandled cases.
2016-08-25Increase the time limit used by the test suiteKostis Sagonas
This is required in some really old SPARC machines running Solaris we still have access to.
2016-08-22hipe: Fix amd64 SSE2 encoding crashMagnus Lång
Register allocation could transform something like fmove u32, d99 to fmove $rdx, 0x20($rsp) which is an invalid instruction.
2016-08-22hipe: Fix tailcall stackarg clobber bugMagnus Lång
Since the link register/return address is restored before stack arguments are stored to the frame, we must not use it to store a stack argument. We do that by adding it to the registers clobbered by pseudo_tailcall_prepare.
2016-08-22hipe_arm: Fix translation of shift by 0Magnus Lång
The problem was caused by shift-by-immediate-zero, which wraps to immediate-32 with some shiftops. TODO: Someplace should be modified to crash when these are generated so debugging further instances of this gets easier in the future.

2016-06-28erl_types: Normalise X:=none() pairs in t_map/3Magnus Lång
t_map/3 previously required callers to perform this normalisation, but as t_from_form/5 would sometimes fail to do so, this requirement is relaxed. Bug (ERL-177) reported and shrunk by Luke Imhoff.

2016-06-15hipe: Pattern matching compilation of binaries and bistringsKostis Sagonas
The Core Erlang pattern matching compiler was written long ago, at a time when binaries and bistrings did not really exist in Erlang. This patch, taken from the code of CutEr where it's used for more than a year now, extends the transformation for pattern matching compilation to also include binaries and bistrings. Some code that was found erroneous and causes errors when compiling the transformed code to native code was also taken out while at it. Thanks to @aggelgian for most of the changes in the code.

2016-06-09Remove support for '...' in Maps typesHans Bolinder
It is possible that '...' is added later (OTP 20.0), but for now we are not sure of all details.
2016-06-09dialyzer: Improve the translation of forms to typesHans Bolinder
Spend less of the limited resources on recursive types.
2016-06-09dialyzer: Use a cache when translating forms to typesHans Bolinder
2016-06-09dialyzer: Prepare erl_types:t_from_form() for a cacheHans Bolinder
No change of functionality.
2016-06-09dialyzer: Optimize erl_types:t_form_form()Hans Bolinder
When the translation from forms to types exceeds some limit, it is faster to try small depths first.

2016-05-30Reintroduce erlang:halt/0/1 in erl_bif_types.erlSverker Eriksson
Removed in f9cb80861f169743 when changed impl from C to Erlang. But seems they are needed to keep dialyzer tests happy. Also improved bif_SUITE:shadow_comments to include all exported in module erlang, not just the "snifs". ...which detected that apply/2 was missing Shadowed comment as well.

2016-05-26hipe_llvm: Export hipe literals as LLVM metadataMagnus Lång
LLVM currently hard-codes these. Since it is desirable to be able to change things like PCB layout without requiring a change to LLVM, we export these as LLVM metadata, which can easily be used from LLVM to make it independent of them.

Seems like halt/2 should be a member of this club.
2016-05-25erts: Implement halt/0 and halt/1 in ErlangSverker Eriksson
just to make things simpler.
2016-05-23hipe: Add test suite for verifying optimisationsErik Norgren
* Added a suite opt_verify_SUITE.erl to HiPE that tests for the results of optimisations, with a single testcase that checks that the icode_call_elim optimisation pass does remove calls to maps:is_key/2 where sound and not otherwise. * Made hipe_testsuite_driver only create explicitly listed suites.
2016-05-23Added elimination of maps:is_key/2 calls to HiPEMagnus Lång
* Implemented removal of maps:is_key/2 calls of which the result is known in a new pass during the typed phase, called hipe_icode_call_elim. * Added the option icode_call_elim that enables the hipe_icode_call_elim pass, and made it default for o2.
2016-05-18hipe_llvm: Move elf_format.hrl types to moduleMagnus Lång
Named types, except those for the records in the header files, have been moved from elf*_format.hrl to elf_format.erl. Also: * Use lists instead of element/2-indexed tuples for ELF section and symbol tables. * Enable +warn_export_vars for hipe/llvm/ subdirectory and fix warning. * Extract duplicated code in hipe_llvm module into help function pp_dereference_type/3.
