* sverk/hipe-fix-literal-crc: erts,hipe,dialyzer: Fix hipe checkum of target runtime system erts: Change THE_NON_VALUE to not be hard coded in hipe compiler OTP-12962 OTP-12963 OTP-12964
2015-08-31erts,hipe,dialyzer: Fix hipe checkum of target runtime systemSverker Eriksson
Main problem: A faulty HIPE_LITERAL_CRC was not detected by the loader. Strangeness #1: Dialyzer should ask the hipe compiler about the target checksum, not an internal bif. Strangeness #2: The HIPE_SYSTEM_CRC checksum was based on the HIPE_LITERALS_CRC checksum. Solution: New HIPE_ERTS_CHECKSUM which is an bxor of the two (now independent) HIPE_LITERALS_CRC and HIPE_SYSTEM_CRC. HIPE_LITERALS_CRC represents values that are assumed to stay constant for different VM configurations of the same arch, and are therefor hard coded into the hipe compiler. HIPE_SYSTEM_CRC represents values that may differ between VM variants. By default the hipe compiler asks the running VM for this checksum, in order to create beam files for the same running VM. The hipe compiler can be configured (with "make XCOMP=yes ...") to create beam files for another VM variant, in which case HIPE_SYSTEM_CRC is also hard coded. ToDo: Treat all erts properties the same. Either ask the running VM or hard coded into hipe (if XCOMP=yes). This will simplify and reduce the risk of dangerous mismatches. One concern might be the added overhead from more frequent calls to hipe_bifs:get_rts_param.

2015-08-25dialyzer: Optimize expansion of parameters of opaque typesHans Bolinder
Opaque recursive parameters are expanded faster.
2015-08-25dialyzer: Generalize an argument of erl_types:t_from_form()Hans Bolinder
Add more information about the caller of t_from_form(). Instead of just the module, also provide name of the type, spec, or record where the type form resides.

Thanks to ILYA Khlopotov for pointing the bug out.
2015-08-19dialyzer: Fix a bug concerning parameterized opaque typesHans Bolinder
The example is provided by James Fish in http://erlang.org/pipermail/erlang-questions/2014-December/082204.html. Note that warnings with text such as "the _ variable breaks opaqueness" are still possible.
2015-08-18dialyzer: Use the recently added orddict:orddict/2 typeHans Bolinder
2015-07-11Teach Dialyzer arity of funs with literal arityLuca Favatella
Re-insert logic for `erlang:make_fun/3` in `erl_bif_types`. It had been removed in bd941f5 while type spec-ing `erlang.erl`. Type spec in `erlang.erl` cannot express arity of returned fun based on value of argument hence re-introducing logic in `erl_bif_types`. Re-definition of logic in `erl_bif_types` follows approach in 9d870a0.

2015-06-18dialyzer: Expand opaque types before other typesHans Bolinder
Opaque types need to be expanded before record field types, otherwise any() could be used for opaque types.
2015-06-15dialyzer: Modify warning for comparison of opaque typesHans Bolinder
Comparing two operands for (in)equality is allowed if both operands are of the same unknown opaque type. Since OTP 17, there is a warning if the types of the operands have nothing in common (this cannot happen before OTP 17). However, the warning says there is a test between opaque types, which is wrong. The warning now states that the comparison cannot evaluate to 'true', which is more consistent.
2015-06-15dialyzer: Modify the handling of parametrized opaque typesHans Bolinder
In OTP 17 it is possible to mix types such as dict:dict() and dict:dict(_, _) outside of the dict module (and similarly for some other opaque types in STDLIB), but the results are unfortunately possibly invalid warnings in users' code. In OTP 18 parameterized opaque types with the same name but with different number of parameters are no longer compatible when seen from outside of the module where the types are declared. The types in STDLIB have been updated accordingly; for instance -opaque dict() :: dict(_, _). has been replaced by -type dict() :: dict(_, _).
2015-06-15dialyzer: Simplify some codeHans Bolinder
Remove what it seems redundant checks.
2015-06-15dialyzer: Fix a bug in the expansion of formsHans Bolinder
The check that a modified type of a field is a subtype of the declared type has been moved outside of the expansion of forms to avoid loops.

* legoscia/dialyzer/cache-hipe-binaries/OTP-12779: Dialyzer to cache results of HiPE compilation Change hipe_bifs:system_crc/1 to hipe_bifs:system_crc/0
2015-05-28Dialyzer to cache results of HiPE compilationMagnus Henoch
Cache the results of native compilation in $XDG_CACHE_HOME/dialyzer_hipe_cache. This can reduce the startup time significantly. If XDG_CACHE_HOME is unset, it defaults to $HOME/.cache. See the XDG Base Directory spec for more details: http://standards.freedesktop.org/basedir-spec/basedir-spec-0.7.html Under that directory, create a subdirectory called ARCH-VERSION-CHECKSUM, where ARCH is the HiPE architecture, VERSION is the HiPE version number, and CHECKSUM is the return value of hipe_bifs:system_crc/0. Caching can be disabled by specifying --no_native_cache on the command line.
2015-05-27Update application versionsHans Bolinder
2015-05-25Update runtime_dependencies in application resource filesHans Bolinder
Applications that use the new erl_anno module are depending on STDLIB 2.5. Note that CosNotification, Megaco, SNMP, Xmerl, and Parsetools use the erl_anno module via the Yecc parsers only (the header file in lib/parsetools/include/yeccpre.hrl calls the erl_anno module). HiPE does not call the erl_anno module, but uses an exported type. We have chosen to make HiPE dependent on the erl_anno module.
2015-05-20dialyzer: Document dialyzer:gui() option 'check_plt'Hans Bolinder
* Mention the option 'check_plt' among gui() options. * No longer check a PLT twice when the analysis type is 'plt_check'. * No longer raise a case_clause error when checking a PLT finds warnings. Thanks to James Fish.

2015-05-05Fix a bug related to constraints generated for erlang:'*'/2Stavros Aronis
For Rst = A1 * A2, typesig for erlang:'*'/2 was constraining the arguments A1 and A2 in the 'reverse' direction by requiring that A2 is a subtype of Rst div A1, unless A1 is a hard zero. This is not correct: if for example both Rst and A1 are non_negative, such a constraint will first force A1 to be non-zero for the division to go through and then require A2 to be non_negative as non_negative div positive = non_negative, always (see commited test). In the fixed version, we are not constraining an argument if the other operand *may* be zero.
