This document describes the changes made to the Compiler application.

-
Compiler 7.1 - -
Fixed Bugs and Malfunctions - - -

For many releases, it has been legal to override a BIF - with a local function having the same name. However, - calling a local function with the same name as guard BIF - as filter in a list comprehension was not allowed.

-

- Own Id: OTP-13690

- - -

compile:forms/2 would not return the module name as - documented when one of the options 'from_core', - 'from_asm', or 'from_beam' was given. Also, - the compiler would crash if one of those options was - combined with 'native'.

Improvements and New Features - - -

- Optimized test for tuples with an atom as first element.

-

- Own Id: OTP-12148

- - -

- Compilation of modules with huge literal binary strings - is now much faster.

-

- Own Id: OTP-13794

- - -

Replaced usage of deprecated symbolic time - unit representations.

-

- Own Id: OTP-13831 Aux Id: OTP-13735

- - -

The undocumented and unsupported module - sys_pre_expand has been removed. As a partical - replacement for the functionality, there is a new - function erl_internal:add_predefined_functions/1 - and erl_expand_records will now add a module - prefix to calls to BIFs and imported functions.

-

- Own Id: OTP-13856

- - -

The internal compiler passes now start all generated - variables with "@" to avoid any conflicts with variables - in languages such as Elixir or LFE.

-

- Own Id: OTP-13924

- - -

The function fmod/2 has been added to the - math module.

-

- Own Id: OTP-14000

- - -

Code generation for complicated guards have been - improved.

-

- Own Id: OTP-14042

- - -

- The compiler has new warnings for repeated identical map - keys.

-

- A map expression such as,

-

- #{'a' => 1, 'b' => 2, 'a' => 3}.

-

- will produce a warning for the repeated key 'a'.

-

- Own Id: OTP-14058

- - -

By default, there will now be a warning when - export_all is used. The warning can be disabled - using nowarn_export_all.

-

- Own Id: OTP-14071

- - -

- Optimize maps pattern matching by only examining the - common keys in each clause first instead of all keys. - This will reduce the number of lookups of each key in - maps pattern matching.

-

- Own Id: OTP-14072

- - -

There is a new 'deterministc' option to omit - 'source' and 'options' tuples in the BEAM - file.

-

- Own Id: OTP-14087

- - -

- Analyzing modules with binary construction with huge - strings is now much faster. The compiler also compiles - such modules slightly faster.

-

- Own Id: OTP-14125 Aux Id: ERL-308

- - -

Atoms may now contain arbitrary Unicode - characters.

-

- Own Id: OTP-14178

- - -

compile:file/2 now accepts the option - extra_chunks to include extra chunks in the BEAM - file.

-

- Own Id: OTP-14221

- - -

The format of debug information that is stored in BEAM - files (when debug_info is used) has been changed. - The purpose of the change is to better support other - BEAM-based languages such as Elixir or LFE.

-

All tools included in OTP (dialyzer, debugger, cover, - and so on) will handle both the new format and the - previous format. Tools that retrieve the debug - information using beam_lib:chunk(Beam, - [abstract_code]) will continue to work with both the - new and old format. Tools that call - beam_lib:chunk(Beam, ["Abst"]) will not work with - the new format.

-

For more information, see the description of - debug_info in the documentation for - beam_lib and the description of the - {debug_info,{Backend,Data}} option in the - documentation for compile.

-

- Own Id: OTP-14369 Aux Id: PR-1367

- - -

In a future release, erlang:get_stacktrace/0 - will probably only work when called from within a - 'try' expression (otherwise it will return - [].

-

To help prepare for that change, the compiler will now - by default warn if 'get_stacktrace/0' is used in a - way that will not work in the future. Note that the - warning will not be issued if 'get_stacktrace/0' - is used in a function that uses neither 'catch' - nor 'try' (because that could be a legal use if - the function is called from within a 'try'.
