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).
|
|
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
|
|
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.

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.

Introduce the line/1 instruction in the compiler and the BEAM
virtual machine. It will not yet be generated by the compiler and
will not actually carry any information.

concat_binary/1 was deprecated in R13B04, but already in
the R10B-2 release, the documentation recommends using
list_to_binary/1 instead.
|
|
An incorrect spec, rpc:yield/1, has been fixed.
|
|
|
|
While at it:
1. Moved types in their proper place
2. Did minor cleanups and
3. Took out an unused function

Also fixed a bunch of "end-years" (was 2010 but should have been 2011,
which the commit hook not happy with).

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).

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.

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.
