Alignment of scheduler data and run queues were adjusted.
2010-06-03OTP-8666 Enable automatic binding of schedulers when possibleRickard Green
The runtime system will by default bind schedulers to logical processors using the default_bind bind type if the amount of schedulers are at least equal to the amount of logical processors configured, binding of schedulers is supported, and a CPU topology is available at startup. NOTE: If the Erlang runtime system is the only operating system process that binds threads to logical processors, this improves the performance of the runtime system. However, if other operating system processes (as for example another Erlang runtime system) also bind threads to logical processors, there might be a performance penalty instead. If this is the case you, are are advised to unbind the schedulers using the <seealso marker="erl#+sbt">+sbtu</seealso> command line argument, or by invoking <seealso marker="erlang#system_flag_scheduler_bind_type">erlang:system_flag(schedule r_bind_type, unbound)</seealso>.

2010-06-03Add infrastructure for the -export_type() attributeKostis Sagonas
erl_lint has been updated so that it takes the new -export_type() attribute into account. This means: - do not complain about types which are defined but nowhere used in the module but exported to other modules - check that all types which are exported are indeed defined in the module - warn when there are multiple occurrences of exported types. In doing this change, I've also taken the liberty to introduce many types and specs for functions of this module and to do small cleanups here and there.
2010-06-03OTP-8665 epp bugHans Bolinder
The Erlang code preprocessor (epp) did not correctly handle premature end-of-input when defining macros. This bug, introduced in STDLIB 1.16, has been fixed.
2010-06-03Merge branch 'pan/otp_8579_autoimport_override' into devErlang/OTP
* origin/pan/otp_8579_autoimport_override: Update preloaded modules Update primary bootstrap Remove outcommented code from erl_lint Make port_command/3 auto-imported Remove (harmless) warnings about min/max in core applications Autoimport min/2 and max/2 Improve coverage of erl_int in testcases Change warning to error for nowarn_bif_clash compiler directive Add -compile({no_auto_import,[F/A]}) doc to compiler.xml Add some testcases to compiler to verify that overriding really happens Return nowarn_bif_clash functionality but with warning Teach erl_lint to better override BIFs with local functions and imports Teach compiler to override autoimport with import First prototype for local functions overriding autoimported OTP-8579 Local functions should override auto-imported Local and imported functions now override the autoimported BIFs when the names clash. The pre R14 behaviour was that autoimported BIFs would override local functions. To avoid that old programs change behaviour, the following will generate an error: Doing a call without explicit module name to a local function having a name clashing with the name of an autoimported BIF that was present (and autoimported) before OTP R14A Explicitly importing a function having a name clashing with the name of an autoimported BIF that was present (and autoimported) before OTP R14A Using any form of the old compiler directive nowarn_bif_clash If the BIF was added or autoimported in OTP R14A or later, overriding it with an import or a local function will only result in a warning, To resolve clashes, you can either use the explicit module name erlang to call the BIF, or you can remove the autoimport of that specific BIF by using the new compiler directive -compile({no_auto_import,[F/A]})., which makes all calls to the local or imported function without explicit module name pass without warnings or errors. The change makes it possible to add autoimported BIFs without breaking or silently changing old code in the future. However some current code ingeniously utilizing the old behaviour or the nowarn_bif_clash compiler directive, might need changing to be accepted by the compiler.
2010-06-03Merge branch 'pan/otp_8577_re_pattern_doc' into devErlang/OTP

I.e os:find_executable("werl.exe") will work as os:find_executable("werl").

2010-06-02Return nowarn_bif_clash functionality but with warningPatrik Nyblom
Wrote and changed some tests in stdlib:erl_lint_SUITE nowarn_bif_clash is obsoleted but will remove warnings and errors about bif clashes. The recommended way is to use no_auto_import directives instead. Hopefully erlang.erl is the only user in the world of nowarn_bif_clash.
2010-06-02Teach erl_lint to better override BIFs with local functions and importsPatrik Nyblom
Added only a few testcases in compiler:error_SUITE and guard_SUITE The new behaviour of warnings and errors when overriding autoimported BIF's: Bifs that were autoimported before R14 are dangerous because old code using them and overriding them in exports can start behaving differently. For newly added autoimports this can't happen to the new code that wants to (or dont want to) use them, why only warnings are added for the BIFs autoimported after the compilator change. Errors are issued only for code that could have worked in one way in R13 and now will behave in a different way. If overriding autoimport with local function: - if explicit -compile directive supresses autoimport -> no message else - if called from inside module - if pre R14 autoimported bif -> error else -> warning else -> no message If overriding autoimport with import directive - if explicit -compile directive supresses autoimport -> no message else (regardless of actual usage) - if pre R14 autoimported bif -> error else -> warning Calls of local functions or imports overriding autoimported functions (either post R14 or by using explicit -compile supressions of autoimport) always goes to the local function or the imported. The compileation errors are added to not let code like this silently and disastrously change its semantic (probably to an infinite loop) between R13 and R14: ---------- -module(m). -export([length/1]). length(X) -> ... Y = length(Z), .... ---------- The user has to select if he/she wants to call length in 'erlang' explicitly or if the overriding semantics is desired, in which case the -compile directive has to be used. -compile({no_auto_import,[F/A]}). Is added to allow to override the autoimports so that code gets unanbiguous. The directive will remove an autoimport even if there is no local function or import overriding, because any other behaviour would be inconsistent and confusing. record_info and module_info can never be overridden.
