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.
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.
2017-09-11Introduce 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...

The 'S' operand type was added in 5bf73db9fd77.
2017-09-11Check the right side of a transformation betterBjörn Gustavsson
The right side of a transformation must be either a single call to a transformation function OR a list of instructions. Mixing them like this is not supported: some_instruction A B C => gen_something(A) | other B C Unfortunately, beam_makeops would silenty ignore anything after the function call, basically handling it in the same way as: some_instruction A B C => gen_something(A) Add a sanity check to reject such mixed right-hand sides.

Besides being noisy, they were already defined by a global Unix- specific header, causing the Windows build to fail if one forgot to define them.

All operations will now yield appropriately, allowing them to be used freely in concurrent applications. This commit also deprecates the functions listed below, although they won't raise deprecation warnings until OTP 21: zlib:adler32 zlib:crc32 zlib:inflateChunk zlib:getBufSize zlib:setBufSize The behavior of throwing an error when a dictionary is required for decompression has also been deprecated.
