2018-09-12[error_logger] Handle report_cb with arity 2Siri Hansen
2018-09-12[proc_lib] Improve crash reports for single line loggingSiri Hansen
2018-09-12[logger] Include single_line option to report_cbSiri Hansen
If the report callback function has two arguments, the second argument is a map with options to limit the size of the log event. To even allow a better formatting when the event shall be printed on a single line, the new option single_line is now included in this argument.
2018-09-12[logger] Check for deadlock when removing filtersSiri Hansen
If a filter fails, it is removed by a call to logger:remove_filter/1,2. If the log event that caused the failure was issued on the logger process itself, this would earlier cause a deadlock due to a gen_server:call to self(). This is now prevented.

2018-09-12[logger] Update doc about file options in logger_std_hSiri Hansen
2018-09-12[logger] Remove encoding option from logger_formatterSiri Hansen
The encoding option was introduced in commit 270d909696a753af022df72a404c73f2895b4a02, to allow report callbacks to format according to a given encoding. There was, however, no connection between this encoding option, and the encoding of the device to which the logger handler was writing. Since a formatter is defined to return unicode:chardata(), and in order to avoid mismatch with the encoding of the device, the encoding option is now removed from the formatter. The handler itself must make sure that it does not write illegal data to its device.

2018-09-12beam_ssa_opt: Don't do CSE for tuple_size/1Björn Gustavsson
Not doing CSE for tuple_size/1 seems to generate slightly better code in most cases.
2018-09-12beam_ssa_opt: Slightly optimize compile-time performance of CSEBjörn Gustavsson
2018-09-12beam_ssa_opt: Slightly optimize performance of live optimizationBjörn Gustavsson
Phi nodes with only literals are fairly common, so it's worthwhile to optimize this case.
2018-09-12beam_ssa_opt: Add an optimization of tuple_size/1Björn Gustavsson
This optimization working on the SSA format will replace the similar optimization in beam_dead. See the comment for an explanation of what the new optimization does.
2018-09-12beam_ssa_opt: Add simplification of switch listsBjörn Gustavsson
When the argument for a #b_switch{} comes from a phi node with only literal values, the switch list could be pruned to only contain the possible values. It could also be possible to eliminate the failure label. Also simplify a switch with a single value list or switch that can be replaced with an is_boolean test.
2018-09-12beam_ssa_opt: Add a pass for coalescing phi nodesBjörn Gustavsson
Nested cases can led to code such as this: 10: _1 = phi {literal value1, label 8}, {Var, label 9} br 11 11: _2 = phi {_1, label 10}, {literal false, label 3} The phi nodes can be coalesced like this: 11: _2 = phi {literal value1, label 8}, {Var, label 9}, {literal false, label 3} Coalescing can help other optimizations, and can in some cases reduce register shuffling (if the phi variables for two phi nodes happens to be allocated to different registers).
2018-09-12beam_ssa_opt: Fix liveness optimizationBjörn Gustavsson
Add more instructions to the list of functions that can be safely removed if their values are not used. This is necessary for correctness when doing more aggressive optimizations. Without this change, the 'succeeded' instruction could be optimized away leaving just the instruction followed by an unconditional branch, which the beam_ssa_codegen does not know how to handle. Here is an example: _3 = bs_start_match _1 br label 13 By adding bs_start_match to the list, the bs_start_match instruction will be removed too. (If the result of bs_start_match is actually used, the succeeded instruction would not be removed.) While we are it, rename the misnamed function is_pure/1 to no_side_effect/1 and move it to beam_ssa. is_pure/1 is a bad name because bif:get has no side effect, but is not pure.
2018-09-12beam_peep: Add is_boolean optimization of select_valBjörn Gustavsson
A select_val instruction that test whether a register is a boolean like this: {select_val,Reg,{f,Fail},{list,[{atom,true},Lbl,{atom,false},Lbl]}}. can be replaced with an is_boolean test: {test,is_boolean,{f,Fail},[Reg]}. {jump,{f,Lbl}}. This optimization is currently done in beam_dead. However, if done in the beam_peep, it can catch more opportunities to do the optimization, because after having run beam_jump, labels that were different have been coalesced.
2018-09-12Fix unsafe optimization in beam_deadBjörn Gustavsson
Those optimizations are unsafe if beam_dead has been run before.
2018-09-12Introduce the beam_jump:instr_labels/1 functionBjörn Gustavsson
This functionality will soon be needed.
2018-09-12Move two optimizations from beam_dead to beam_aBjörn Gustavsson
The 'move' instruction can be eliminated in code such as: {test,is_eq_exact,{f,42},[{x,0},{atom,value}]}. {move,{atom,value},{x,0}}. Move that optimization from beam_dead to beam_a. The optimization will be simpler because the 'move' instruction has not yet been moved into a block. Getting rid of 'move' earlier will also save work for later passes. Also move the optimization that eliminates instructions such as from beam_dead to beam_a: {test_is_eq_exact,{f,42},[{x,0},{x,0}]}.
2018-09-12beam_ssa: Optimize linearize/1 and rpo/2Björn Gustavsson
It is faster to use cerl_sets instead of gb_sets to keep track of seen blocks.
2018-09-12beam_ssa: Add trim_unreachable/1Björn Gustavsson
Add trim_unreachable/1 to remove unreachable blocks and adjust phi nodes.
