Those clause are obsolete and never used by common_test.

2016-02-25code: Add functions that can load multiple modulesBjörn Gustavsson
Add functions to 'code' to allow loading of multiple modules at once. code:atomic_load(Modules) will load all modules at once, or fail having loaded none of them. Since we cannot guarantee the atomicity if there are modules with -on_load functions, the list of modules must not contain any modules with an -on_load function. Also, to make it possible to put an application into an inactive state for as short time as possible, also add code:prepare_loading/1 and code:finish_loading/1. They are used like this: {ok,Prepared} = code:prepare_loading(Modules) . . . ok = code:finish_loading(Prepared) code:ensure_modules_loaded/1 is useful as a pure optimization to ensure that modules that will be needed soon have indeed been loaded. It will not reload modules that have already been loaded and it *will* accept modules that have an on_load function. Therefore, it does not make sense to give any atomicity guarantees. I did consider overloading the existing code:ensure_loaded/1 function, but rejected it because the return value is very different. Having different forms of return values depending on the types of arguments is confusing.
2016-02-25Refactor post_beam_load handlingBjörn Gustavsson
After loading a module without native code, it is still necessary to call hipe_unified_loader:post_beam_load() to ensure that any native calls to the module is done to the newly loaded module (and not to a previous version of the module in native code). Unfortunately, hipe_unified_loader:post_beam_load() can be slow and most of the time it doesn't do anything because no previous native code was loaded. Therefore, ad2962278f added a kludge using the process dictionary to avoid calling post_beam_load() if no native code at all has been loaded. Remove the kludge by keeping track exactly of which modules that have native code in the existing ets table. Also generalize post_beam_load() to handle severals modules at once, since we will soon need that functionality.
2016-02-25Simplify and robustify code_server:all_loaded/1Björn Gustavsson
The main ets table kept by code_server contains several pieces of information. Therefore, code_server:all_loaded/1 need to filter the information in the table. code_server:all_loaded/1 can be simplified if we use ets:select/2. Currently, the filtering is done by filtering away unwanted stuff ({sticky_dir,Mod} tuples). It is more robust to filter on the stuff that we want to keep ({Mod,Path} tuples, where Mod is an atom) in case that we'll add more auxiliary records to the table later.
2016-02-25Add erl_prim_loader:get_modules/3Björn Gustavsson
When we are going to implement functions that can load many modules at once, we don't the erl_prim_loader server to become a bottleneck. Therefore, we need erl_prim_loader:get_modules/3 that can read many BEAM files in parallel. Note that we will not bother making reading from archive files or using the inet loader efficient. That can be done later if it turns out to be important.

2016-02-25Modernize use of timetrapsBjörn Gustavsson
Either rely on the default 30 minutes timetrap, or set the timeout using the supported methods in common_test.

2016-02-25Produce warnings for binary patterns that will never matchBjörn Gustavsson
Binary matching can be confusing. For example: 1> <<-1>> = <<-1>>. ** exception error: no match of right hand side value <<"ÿ">> 2> When constructing binaries, the value will be masked to fit in the binary segment. But no such masking happens when matching binaries. One solution that we considered was to do the same masking when matching. We have rejected that solution for several reasons: * Masking in construction is highly controversial and by some people considered a bad design decision. * While masking of unsigned numbers can be understood, masking of signed numbers it not easy to understand. * Then there is the question of backward compatibility. Adding masking to matching would mean that clauses that did not match earlier would start to match. That means that code that has never been tested will be executed. Code that has not been tested will usually not work. Therefore, we have decided to warn for binary patterns that cannot possibly match. While we are it, we will also warn for the following example where size for a binary segment is invalid: bad_size(Bin) -> BadSize = bad_size, <<42:BadSize>> = Bin. That example would crash the HiPE compiler because the BEAM compiler would generate a bs_get_integer2 instruction with an invalid size field. We can avoid that crash if sys_core_fold not only warns for bad binary pattern, but also removes the clauses that will not match.
