2019-02-01inline_SUITE: Don't start a slave nodeBjörn Gustavsson
A long time ago there was a good idea to run compiled code in a slave node. Nowadays, not so much.
2019-02-01Correct test_lib:is_cloned_mod/1Björn Gustavsson
test_lib:is_cloned_mod(inline_SUITE) would return true.
2019-02-01sys_core_fold_lists: Propagate annotations in expansion of lists functionsBjörn Gustavsson
There could be a warning with a `no_file` atom instead of filename and line number.
2019-02-01Parallelize compile_SUITE:bc_options/1Björn Gustavsson
2019-02-01Remove the optimized_guard/1 test caseBjörn Gustavsson
With the new SSA code passes, the optimized_guard/1 test case has become really bad at finding unnecessary `and` and `or` instructions.
2019-02-01Make helper functions tail-recursiveBjörn Gustavsson
Two helper functions in beam_ssa_opt and beam_ssa_dead are body-recursive for no good reason. While at it, add some clarifying comments to the functions.
2019-02-01Optimize beam_ssa:def_used/2Björn Gustavsson
beam_ssa:def_used/2 is used by beam_ssa_pre_codegen when reserving Y registers. Do the following optimizations: * Use an ordset instead of a gb_set. When the only operation performed on a set is union/2, an ordset will usually be faster, especially when the result is an ordset. * Use a cerl_set instead of a gb_set for the set of all possible predecessors. cerl_sets is usually faster than gb_sets.
2019-02-01Prefer map syntax and guard BIFs over the maps modulesBjörn Gustavsson
Avoiding calls usually reduces the size of the stack frame and reduces register shuffling.
2019-02-01beam_ssa_type: Optimize calculation of variables that are only used onceBjörn Gustavsson
2019-02-01Use gb_sets:delete/2 instead of gb_sets:delete_any/2Björn Gustavsson
Save a little time by using gb_sets:delete/2 instead of gb_sets:delete_any/2 when the key is known to be in the set.
2019-02-01Speed up beam_ssa_dead when there are many sequential blocksBjörn Gustavsson
beam_ssa_dead could be very slow if there were many blocks connected with unconditional branches (for example, if a block had contained many `call` instructions and been split by ssa_opt_split_blocks). It turns out that `comb_get_sw/3` does an unnecessary (and perhaps incorrect) recursive call to itself when the terminator for the block is an unconditional branch. Removing the recursive call does not disable any optimizations, but will be much faster if there are many blocks connected with unconditional branches. Reported-by: Michał Muskała
2019-02-01Optimize ssa_opt_sink when nothing can be sunkBjörn Gustavsson
Compilation will be much faster if there are many blocks, but no get_tuple_element instructions. Reported-by: Michał Muskała

2019-02-01erts: Remove dead ERTS_MAGIC_REF_BIF_TIMERS codeLukas Larsson
Using magic refs for big timers caused too large a stress on the off_heap GC implementation to be viable, so it was never enable. The code is now broken because of other changes to we might as well remove it.

2019-01-31Fix internal consistency failure caused by beam_exceptBjörn Gustavsson
Fix a bug where the number of live registers in a `bs_get_tail` instruction was too low. Consider this example: -export([bs_get_tail/2]). bs_get_tail(Bin, Config) -> bs_get_tail_1(Bin, 0, 0, Config). bs_get_tail_1(<<_:32, Rest/binary>>, Z1, Z2, F1) -> {Rest,Z1,Z2,F1}. `beam_validator` would emit the following diagnostics: t: function bs_get_tail_1/4+2: Internal consistency check failed - please report this bug. Instruction: {func_info,{atom,t},{atom,bs_get_tail_1},4} Error: {uninitialized_reg,{x,3}}: Here is the part of the code that generates the `function_clause` exception before the optimization: {test_heap,6,4}. {put_list,{x,3},nil,{x,2}}. {put_list,{integer,0},{x,2},{x,2}}. {put_list,{integer,0},{x,2},{x,2}}. {bs_set_position,{x,1},{x,0}}. {bs_get_tail,{x,1},{x,0},3}. %3 live registers. {test_heap,2,3}. {put_list,{x,0},{x,2},{x,1}}. {move,{atom,function_clause},{x,0}}. {line,[{location,"t.erl",8}]}. {call_ext_only,2,{extfunc,erlang,error,2}}. The `bs_get_tail` instruction expects that 3 registers will be live at this point. `beam_except` rewrites the code like this: {bs_set_position,{x,1},{x,0}}. {bs_get_tail,{x,1},{x,0},3}. %Still 3. Too low. {move,{integer,0},{x,1}}. {move,{integer,0},{x,2}}. {jump,{f,3}}. Now the number of live registers in `bs_get_tail` is too low, because the `{x,3}` register will become undefined. This commit adds code to update the number of live registers in the `bs_get_tail` instruction, producing this code: {bs_set_position,{x,1},{x,0}}. {bs_get_tail,{x,1},{x,0},4}. %Adjusted to 4. {move,{integer,0},{x,1}}. {move,{integer,0},{x,2}}. {jump,{f,3}}.

2019-01-31[ct] Add option {newline,string()} to ct_telnet:cmd and ct_telnet:sendSiri Hansen
By default, each command is appended with "\n", but in some cases a command must end with "\r\n" to evaluate correctly. This can now be specified with option {newline,"\r\n"}.
2019-01-31[observer] Don't crash on Log > Toggle Log ViewSiri Hansen
Since Logger was introduced in OTP-21.0, menu choice Log > Toggle Log View in observer would cause a crash unless an error_logger event handler was explicitly installed. This is now corrected.
2019-01-31Optimize calendar:gregorian_days_to_date/1Stanislav Mayorov
This patch improves the performance of calendar:gregorian_days_to_date/1 by changing the algorithm for finding the year to log-logarithmic. The old implementation has linear complexity, which makes function too slow for large values. For example: There is an API that allows you to create events for future dates. There are users of this API who, for some reasons, choose dates very far in the future. In such conditions, function works very slow. New implementation based on interpolation search, takes 1 or 2 iterations at most cases and free from such a flaw. A unit test was also developed to illustrate the speed of a function at large values.
