2016-02-08dialyzer: Fix a bug concerning the option 'plt_remove'Hans Bolinder
[James Fish:] Dialyzer always asserts that files and directories passed in its options exist. Therefore it is not possible to remove a beam/module from a PLT when the beam file no longer exists. Dialyzer should not to check files exist on disk when removing from the PLT.

2016-01-27Clarify usage of coordinator by analysis_callgraphLuca Favatella
* Comment in dialyzer_analysis_callgraph what the call to dialyzer_coordinator does; * Delegate activation request to each dialyzer_worker; * There is no reason for the dialyzer_coordinator to request activation on behalf of the workers: let each worker request its own activation as it leads to more consistent dialyzer_worker module (activation is request as soon as status running is hit - reguardless of mode) and it reduces lines of code. * Clarify types in coordinator and worker e.g. make opaque and make type more strict.

2016-01-11Fix inadvertent deletion of callback infoStavros Aronis
If a behaviour module contains an non-exported function with the same name as one of the behaviour's callbacks, the callback info was inadvertently deleted from the PLT as the dialyzer_plt:delete_list/2 function was cleaning up the callback table. This bug was reported by Brujo Benavides. Fixes ERL-72 bug report.

2016-01-11Remove dead code related to missing behaviour infoStavros Aronis
Dialyzer used to report unknown behaviours in the same way as unknown functions and types. This functionality has been removed in d101155, but some code remained.

* 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.

Opaque types need to be expanded before record field types, otherwise any() could be used for opaque types.

* 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.
2015-05-25Update 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.
