* 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: Generalize an argument of erl_types:t_from_form()Hans Bolinder

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.

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.
2015-05-25Update 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.

A minor re-factoring and generalization.
2014-10-08dialyzer: Ignore ERL_COMPILER_OPTIONS when compilingHans Bolinder
If, for instance, 'warn_unused_import' is present in ERL_COMPILER_OPTIONS then many files in Erlang/OTP (Kernel, STDLIB, ...) cannot be analyzed by Dialyzer since the option is not present when compiling Erlang/OTP, but 'warnings_as_errors' is. The case that ERL_COMPILER_OPTIONS contains 'warnings_as_errors' can only be handled by ignoring ERL_COMPILER_OPTIONS.
2014-10-08dialyzer: fix bug concerning compiler option 'warnings_as_errors'Hans Bolinder
A typical scenario: the type digraph() is used in R16 (compilation with the option 'warnings_as_errors' results in no warning); then the module is analyzed by a 17 Dialyzer where digraph() is obsolete, and since the warning is turned into an error Dialyzer fails to load the module. Thanks to Michael Truog.

2014-06-17[dialyzer] Fix handling of literal recordsHans Bolinder
This ticket is about records in Erlang code, and when to check the fields against the (optional) types given when defining records. Dialyzer operates on the Erlang Core format, where there are no trace of records. The fix implemented is a Real Hack: Given the new option 'dialyzer' erl_expand_records marks the line number of records in a way that is undone by v3_core, which in turn inserts annotations that can be recognized by Dialyzer.
