2010-11-29Fix type information of 'file' and 'code' modulesKostis Sagonas
Dialyzer for a long time now has had hard-coded type information about key functions of the 'file' and 'code' modules in 'erl_bif_types'. Some of this information was not up-to-date according to the published Erlang/OTP documentation, while some other part contained small errors. Now that specs are available, this information should be moved to the corresponding files, not be hard-coded in erl_bif_types. This change takes out all information for the 'file' module and fixes some small errors in type information for the 'code' module.

2010-11-22erl_types: Fix pretty rare crashes and an infinite loopKostis Sagonas
- Fixed pretty rare crash when taking the infimum of two tuple_sets (initial fix by Kostis Sagonas but then a better fix was provided by Stavros Aronis and this is the one adopted). - Fixed pretty rare crash when using parameterized types containing unbound variables (thanks to Nicolas Trangez for reporting it). - Fixed pretty rare infinite loop when refining the types of an SCC whose functions all returned none() (thanks to Stavros Aronis).

* ks/rec-erl_types: Deeper unfolding of recursive types
2010-10-29Deeper unfolding of recursive typesKostis Sagonas
The change of taking out some hard-coded information about the file module uncovered that the unfolding of recursive types was probably too shallow. This has been fixed by unfolding it until a deeper limit (REC_TYPE_LIMIT). While at erl_types.erl also did some cleanup changes and fixed an erroneous io:format message.
2010-10-20hipe: Add translation of BIFs with arity threeKostis Sagonas
2010-10-15Update httppacket type to return both strings and binariesLukas Larsson
2010-10-14Add the {encoding, _} options to file:open/2's modesKostis Sagonas
Although the {encoding, encoding()} set of options is documented in the manual page of the 'file' module, they do not appear in the Mode description on that page nor in the mode() type declaration. The patch adds this information in both the code of the module and the documentation of the module. To avoid duplication, the declaration of the encoding() type is added to the 'unicode' module where it most probably belongs. While at it, added a proper declaration for posix(), took out the now superfluous information about the types of file:open/2 from the erl_bif_types module, and corrected the return type of file:open/2 so that it corresponds to the published documentation.

* ks/dialyzer-fixes: Fix two errors in dialyzer
2010-09-24Fix two errors in dialyzerKostis Sagonas
Changes which fix some problems reported by dialyzer users: 1. The handling of nested opaque types 2. The handling of remote types in record expressions used as types While at it, updated dialyzer's RELEASE_NOTES to reflect these fixes and did some cleanups to dialyzer_utils.erl so that it gets in sync with dialyzer's main development branch.

2010-08-30fix crash in hipe_icode_exceptionsMikael Pettersson
This fixes a problem in the HiPE compiler's BEAM-to-Icode pass where it can crash due to the BEAM compiler's merging of identical basic blocks with different exception handling contexts. This bug has been latent, but is now exposed by what appears to be more aggressive optimizations in BEAM. The added comment explains things in more detail.
2010-08-27Fix hipe:load/1Paul Guyot
hipe:load/1 (and unexported hipe:load/2) just did not work. Calling it would fail with a badmatch because only the hipe chunk was passed to do_load/3's third parameter called WholeModule. Since this parameter is then passed to beam_lib:all_chunks/1 which accepts the whole module as a binary as well as a path to the beam file, and since a path is exactly what we have in load/2, the fix consists in letting do_load/3 accept a path and passing it from load/2.
2010-08-17erts: Remove broken elib_mallocBjörn Gustavsson
elib_malloc is an alternate memory allocator that is no longer possible to build.
2010-07-20One off-heap list, to eliminate two words per ETS object.Sverker Eriksson
Merging the three off-heap lists (binaries, funs and externals) into one list. This reduces memory consumption by two words (pointers) per ETS object.
2010-07-07Fix a bug in the type of lists:flatmap/2.Kostis Sagonas
The code handling this BIF did not take into account that the fun in the first argument that could return [] and therefore the return value of the BIF could also be [].

In measurements we saw speed-ups compared to the old eprof ranging from 6 times (for sequential code that only uses one scheduler/core) up to 84 times (for parallel code that uses 8 cores).

* ks/dialyzer-R14-fixes: Various changes to dialyzer-related files for R14. OTP-8699 ks/dialyzer-R14-fixes Various changes to dialyzer-related files for R14. - Dialyzer properly supports the new attribute -export_type and checks that remote types only refer to exported types. A warning is produced if some files/applications refer to types defined in modules which are neither in the PLT nor in the analyzed applications. - Support for detecting data races involving whereis/1 and unregister/1. - More precise identification of the reason(s) why a record construction violates the types declared for its fields. - Fixed bug in the handling of the 'or' guard. - Better handling of the erlang:element/2 BIF. - Complete handling of Erlang BIFs.
