2014-02-23Deprecate pre-defined built-in typesHans Bolinder
The types array(), dict(), digraph(), gb_set(), gb_tree(), queue(), set(), and tid() have been deprecated. They will be removed in OTP 18.0. Instead the types array:array(), dict:dict(), digraph:graph(), gb_set:set(), gb_tree:tree(), queue:queue(), sets:set(), and ets:tid() can be used. (Note: it has always been necessary to use ets:tid().) It is allowed in OTP 17.0 to locally re-define the types array(), dict(), and so on. New types array:array/1, dict:dict/2, gb_sets:set/1, gb_trees:tree/2, queue:queue/1, and sets:set/1 have been added.

* ks/hipe-cleanup-escaping/OTP-11031: Loosen the assumptions of code that handles escaping functions
2013-03-12Loosen the assumptions of code that handles escaping functionsKostis Sagonas
The HiPE compiler implicitly relied on the assumption that a function will never appear as both exported and also used as function closure. This was true because the BEAM compiler prior to R16B created module local anonymous functions for each closure. A proposed change to the BEAM compiler invalidates this invariant, so in order to accommodate for this change there needs to be a change of how the set of possibly escaping functions is computed. While doing this, the code was simplified by taking out a boolean() tag that indicated whether a function is a closure or exported and also slightly cleaned up the affected modules.

2013-02-25Fix bug related to the handling of is_number/1 by the range analysisKostis Sagonas
The following module produced erroneous results when compiled with HiPE: -module(a). -export([foo/1]). foo(X) when is_number(X) -> is_integer(X). Running: 1> c(a). 2> a:foo(0). true 3> hipe:c(a). 4> a:foo(0). false % *** WRONG *** The problem was that the 'number' case for the `hipe_icode:type_test/1` was going to the default case where the argument was determined as being something other than an integer. Thanks to Sebastian Egner and Johannes Weißl for bringing the bug into attention. Fixed on the day it was reported.

2011-11-28hipe: Remove single function compilationBjörn Gustavsson
Compiling single functions (as opposed to whole modules) to native code complicates code management in HiPE. It would also vastly complicate whole-module optimizations, such as returning multiple return values instead of tuples within a module. As a first step, remove the external interface for the single compilation feature. In the future, there are many things that could be restructured and simplified.

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).

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.
