2011-08-29Enhance Dialyzer's inference on comparisonsStavros Aronis
This patch makes Dialyzer aware of Erlang's total ordering of terms, enabling discrepancy detection in cases where e.g. integer() < tuple() is treated as a comparison that might also return false (when it is certain to always return true).
2011-08-27Add erlang:external_size/2 BIFFilipe David Manana
This BIF's second parameter is a list of options. Currently the only allowed option is {minor_version, Version} where version is either 0 (default) or 1.

* dev: code: Optimize purge/1 and soft_purge/1 using check_old_code/1 Add erlang:check_old_code/1 check_process_code/2: Quickly return 'false' if there is no old code
2011-08-25Add erlang:check_old_code/1Björn Gustavsson
Add erlang:check_old_code/1 to quickly check whether a module has old code. If there is no old code, there is no need to call erlang:check_process_code/2 for all processes, which will save some time if there are many processes.
2011-08-16emulator: Add a fourth element in exception stacktracesBjörn Gustavsson
This commit is a preparation for introducing location information (filename/line number) in stacktraces in exceptions. Currently a stack trace looks like: [{Mod1,Function1,Arity1}, . . . {ModN,FunctionN,ArityN}] Add a forth element to each tuple that can be used indication the filename and line number of the source file: [{Mod1,Function1,Arity1,Location1}, . . . {ModN,FunctionN,ArityN,LocationN}] In this commit, the fourth element will just be an empty list, and we will change all code that look at or manipulate stacktraces.

concat_binary/1 was deprecated in R13B04, but already in the R10B-2 release, the documentation recommends using list_to_binary/1 instead.

2011-02-14Fix bug in the simplification of inexact comparisonsKostis Sagonas
On 31/1/2011 Paul Guyot reported a bug in the native code compilation of inexact equality/inequality tests between floats and integers. The relevant test was: f(X) -> Y = X / 2, Y == 0. and hipe erroneously evaluated the calls f(0) and f(0.0) to 'false'. The culprit was in the simplification code of the Icode range analysis which used an erroneous test (lists:any/1 instead of lists:all/1).

2011-02-03Fix translation of bs_add's fail labelsKostis Sagonas
2011-01-31Sanitize the specs of the code moduleKostis Sagonas
After the addition of unicode_binary() to the file:filename() type, dialyzer started complaining about erroneous or incomplete specs in some functions of the 'code' module. The culprit was hard-coded information in erl_bif_types for functions of this module, which were not updated. Since these functions have proper specs these days and code duplication (pun intended) is never a good idea, their type information was removed from erl_bif_types. While doing this, some erroneous comments were fixed in the code module and also made sure that the code now runs without dialyzer warnings even when the -Wunmatched_returns option is used. Some cleanups were applied to erl_bif_types too.

2010-12-28Fix native code compiler infinite loop and update type info for 're'Kostis Sagonas
The introduction of filenames being unicode binaries revealed a problem in the type analysis of the native code compiler which resulted in an infinite loop when compiling the 'filename' module. In addition, the hard-coded type information for the built-in functions of the 're' module was out-of-date, which resulted in erroneous type information for 'filelib' functions being stored in the PLT.
