2016-02-02erts: Add ERTS_WRITE_UNLIKELYLukas Larsson
ERTS_WRITE_UNLIKELY can be used to place global variables in a specific section where only data that is very rarely modified sits. This is used to improve cache locality.

2016-01-29Eliminate redundant double is_function testBjörn Gustavsson
When tuple funs were still supported, the idiom for allowing real funs with a certain arity but not tuple funs was: is_function(Fun) andalso is_function(Fun, Arity) The reason that both tests were needed is because: is_function({M,F}) would return 'false' is_function({M,F}, Arity) would return 'true' In 53ec991d19, is_function/2 was updated to only return 'false' for tuples, so the call to is_function/1 can be removed.

2016-01-28Extend cerl_trees:mapfold with a 'pre-order' operationStavros Aronis
When manipulating Core Erlang trees it may be useful to perform some operation when a node is visited, before inspecting children nodes. The definition of cerl_tree:mapfold/3 does not allow that, as it applies the given function only after all the recursive calls on the children nodes have been completed. This patch adds a new argument to mapfold: a function that is applied when a node is first entered. As an example of its use, consider the case where one wants to move a 'call' node earlier, by adding 'let' node and replacing the 'call' node with the defined variable. The name of that variable must be specified before one traverses the inner tree (especially if such replacements can be nested).
2016-01-28Use file read buffering in dbg:trace_clientPéter Gömöri
Trace files are typically large but contain small terms so we can expect a performance gain from read buffering. dbg:trace_client with a dummy handler ran more then 3x faster on a sample 200MB trace file. fprof:profile can also gain a bit.

2016-01-28Update documentation for code-loading functionsBjörn Gustavsson
Some of the error reasons were not explained.
2016-01-28code: Correct the types for error returnsBjörn Gustavsson
The specifications for functions that load code in the 'code' module (e.g. code:load_file/1) have some problems: * The specs claim that the functions can return {error,on_load}, but they never do. However, they can return {error,on_load_failure} if the -on_load function in a module fails. * The specs claim that the functions can return {error,native_code}, but they never do. While we are it, also extend the on_load_errors/1 test case to test that the load functions return {error,on_load_failure} when an -on_load function fails.
2016-01-27code_server: Add types to the state recordBjörn Gustavsson
2016-01-27code_server: Don't export internal system_* functionsBjörn Gustavsson
There is no reason to export system_continue/3 and system_terminate/4 from code_server. Servers that use proc_lib and 'sys' to handle system message do need those functions exported, but code_server contains a modified copy of the system message handling code from 'sys', and that code only make local calls to system_continue/3 and system_terminate/4.
2016-01-27Simplify starting of code serverBjörn Gustavsson
There is unnecessary knowledge about the -nostick option in the 'kernel' module. -nostick can be handled entirely in the 'code' module. There is no need to have both code:start_link/0 and code:start_link/1. code:start_link/0 is sufficient. Also get rid of error handling for things that cannot happen: The 'init' module has made sure that init:get_argument(root) can't fail, so there is no need for any error-reporting code. (See e1dc0aa4.) We also don't need to test the return value from code_server:start_link/1, because it will always return {ok,Pid} (or crash).

2016-01-27Remove first argument of code_server:call()Björn Gustavsson
Remove the first argument for code_server:call(). It makes no sense. The only caller is 'code'. Note that the code_server module is undocumented and that code_server:call() is an internal helper function.
