2017-10-02erts: Some code cleanup for gdb to work betterLukas Larsson
2017-10-02erts: temp_alloc can no longer be disabledLukas Larsson
temp_alloc is used in such a way that if it ever results in a malloc/free sequence it will slow down the system alot. So it will no longer be possible to disable it and it will not be disabled when using +Mea min. OTP-14651
2017-09-15erts: Refactor check_io to use one static structSverker Eriksson
that is shared between _kp and _nkp versions. Makes it easier to access in debugger.

2017-09-15erts: Rename ErtsPollSet_ structS to not confuse gdbSverker Eriksson
by having different structs with same name.
2017-09-15erts: Increase number of check_io-fd-locksSverker Eriksson
and use correct cache alignment.

* bjorn/erts/relative-jumps: Pack failure labels in i_select_val2 and i_select_tuple_arity2 Optimize i_select_tuple_arity2 and is_select_lins Rewrite select_val_bins so that its labels can be packed Pack sequences of trailing 'f' operands Implement packing of 'f' and 'j' Make sure that mask literals are 64 bits Use relative failure labels Add information about offset to common group start position Remove JUMP_OFFSET Refactor instructions to support relative jumps Introduce a new trace_jump/1 instruction for tracing Avoid using $Src more than once
2017-09-14Pack failure labels in i_select_val2 and i_select_tuple_arity2Björn Gustavsson
2017-09-14Optimize i_select_tuple_arity2 and is_select_linsBjörn Gustavsson
Don't save a pointer to the default failure label. That could relieve register pressure. Instead, if we'll need to signal an error in i_select_tuple_arity2, delay to the execution phase. That should be a clear win because i_select_tuple_arity2 very rarely fails because of the term being selected is not a tuple.
2017-09-14Rewrite select_val_bins so that its labels can be packedBjörn Gustavsson
2017-09-14Pack sequences of trailing 'f' operandsBjörn Gustavsson
Pack sequences of trailing 'f' operands for instructions such at jump_on_val or i_select_val_lins.
2017-09-14Implement packing of 'f' and 'j'Björn Gustavsson
2017-09-14Make sure that mask literals are 64 bitsBjörn Gustavsson
Use the "ull" suffix for the mask literals instead of "ul" to ensure that the literals are 64 bits also on Windows.
2017-09-14Use relative failure labelsBjörn Gustavsson
Relative failure in itself is not an optimization, but we plan to pack failure labels in the future to save memory.
2017-09-14Add information about offset to common group start positionBjörn Gustavsson
2017-09-14Remove JUMP_OFFSETBjörn Gustavsson
It has served its purpose.

* maint: stdlib: Fix jumping to beginning or end of line Fix del_chars not considering wide chars and update buffer length before calling write_buf Make cp_pos_to_col function aware of the ANSI escape codes
2017-09-14Merge pull request #1549 from ggcampinho/fix-move-cursorDan Gudmundsson
Consider ANSI escape codes on cp_pos_to_col
2017-09-13Fix del_chars not considering wide chars and update buffer length before ↵Glauber Campinho
calling write_buf After deleting the chars the function `del_chars` was considering the code points to move the cursor back and not the graphemes
2017-09-13Refactor instructions to support relative jumpsBjörn Gustavsson
Introduce new macros that can be used for relative jumps and use them consistently. Test that everything works by using a non-zero constant JUMP_OFFSET. The loader subtracts JUMP_OFFSET from loaded labels, and all instructions that use 'f' operands add it back.

2017-09-11Use 't' instead of 'I' bit syntax operandsBjörn Gustavsson
The number of live registers, unit and flags, and the number of slots all fit comortably in 16 bits. This change will give more opportunities for packing.
2017-09-11Optimize operand type for match context in i_bs_get_integerBjörn Gustavsson
The match context is always in an X register. Change the 's' operand to 'x'. While we are it, also change the operands for Live and FlagsAndUnit to 't' (they will both fit comfortably in 16 bits).
2017-09-11Change operand type from 's' to 'S' for a few instructionsBjörn Gustavsson
'S' is slightly more efficient. Using 'S' may also enable more packing.
2017-09-11Use the correct name of the parameterBjörn Gustavsson
2017-09-11Introduce a new trace_jump/1 instruction for tracingBjörn Gustavsson
As a preparation for introducing relative jumps, introduce "trace_jump W" that can be used for tracing. This instruction will continue to have an absolute address for the jump target. (Note: This instruction is never created during loading; it is only created in stubs when tracing is active.)
2017-09-11Avoid using $Src more than onceBjörn Gustavsson
The C compiler will probably optimize this, but just to be sure...
