2017-08-17Work around unexpected common_test behaviourAnders Svensson
diameter_traffic_SUITE has four layers of nested groups, so when a testcase is run it should get Config from four init_per_group plus one init_per_testcase. This isn't what happens: Config is being accumulated from several init_per_group in some manner that isn't clear, and the skip in the parent commit somehow results in growing test_server_gl:init/1 processes that eventually consume all memory. Replacing rather than prepending to Config in init_per_group works around this, but the common_test behaviour seems wrong.

2017-08-16stdlib: Improve edlin handling of unicode charsDan Gudmundsson
Let edlin handle grapheme clusters instead of codepoints to improve the handling multi-codepoints characters. The ttsl driver (and protocol) still expects all lengths as codepoints. Previously it was expected that each codepoint used (at least) one terminal column for each codepoint, and a hack was made for wide characters (multicolumn) by patching in TAGGED characters to occupy the extra space so that codepoint index was equal column index. This didn't work at all for combining codepoints that do not occupy any more space than the previous character. Improved this handling by calculating column positions in move_cursor. This is based on wcwidth() and is not perfect, wcwidth() is wrong for some codepoints and wcwidth() can not know with Hangul graphemes for example. But it works better than before without making a major change in the protocol.
2017-08-15Slightly optimize updating of mapsBjörn Gustavsson
The instruction put_map_assoc/5 (used for updating a map) has a failure operand, but it can't actually fail provided that its "map" argument is a map. The following code: M#{key=>value}. will be compiled to: {test,is_map,{f,3},[{x,0}]}. {line,[...]}. {put_map_assoc,{f,0},{x,0},{x,0},1,{list,[{atom,key},{atom,value}]}}. return. {label,3}. %% Code that produces a 'badmap' exception follows. Because of the is_map instruction, {x,0} always contains a map when the put_map_assoc instruction is executed. Therefore we can remove the failure operand. That will save one word, and also eliminate two tests at run-time. The only problem is that the compiler in OTP 17 did not emit a is_map instruction before the put_map_assoc instruction. Therefore, we must add an instruction that tests for a map if the code was compiled with the OTP 17 compiler. Unfortunately, there is no safe and relatively easy way to known that the OTP 17 compiler was used, so we will check whether a compiler before OTP 20 was used. OTP 20 introduced a new chunk type for atoms, which is trivial to check.

2017-08-14Apply the redundant test optimisation also in case of fall-throughMichał Muskała
Even though, it's not possible to have fall-throughs when entering the otp pass, it can produce them itself and we're running the pass until fixpoint.
2017-08-14Replace labels instead of inserting duplicates in beam_jumpMichał Muskała
This makes other optimisations more efficient since we have less labels overall.
2017-08-14Enhance elimination of useless tests in beam_jumpMichał Muskała
It can happen we have the following situation: {test,is_tuple,Fail,[R1]} {test,test_arity,Fail,[R1,N1]} {get_tuple_element,R1,N2,R2} {test,is_eq_exaqct,Fail,[R2,Atom]} {jump,Fail} Previously, the optimisation would eliminate the last is_eq_exact test, but we can do more. If the register R2 is not used in Fail, we can eliminate the get_tuple_element instruction as well as all the preceding tests. Ultimately, the whole sequence can be replaced by: {jump,Fail}

2017-08-13Run the sharing optimisation in beam_jump until fixpointMichał Muskała
This is especially useful after inlining a function with a case. Today the compiler would most probably be able to unify all the leafs of the case during the sharing optimisation, but it would fail to unify the pattern matching itself. Naively running the optimisation multiple times wouldn't be able to find the common code either, because it would differ in jump/fail targets of various instructions. To remedy this, after doing each sharing pass we traverse the code backwards when reversing and update all the jump targets with the new targets that were discovered during the unification pass. This allows running the optimisation until fixpoint and makes sure all sharing opportunities will be discovered. This optimisation also helps with the Elixir's `with/else` construct.

2017-08-11Make '0 bsl BigNumber' consistently succeedBjörn Gustavsson
'0 bsl 134217728' would fail with a system limit exception on a 32-bit BEAM machine, but not on a 64-bit BEAM machine. Smaller values on the right would always work. Make erlang:bsl(0, BigNumber) always return 0 to make for consistency. (The previous commit accidentally did that change for '0 bsl BigNumber'.)
