Introduce a new 'Q' type, similar to 'P' except that it
can be packed.
|
|
In the 32-bit BEAM emulator, it is only possible to pack
3 register operands into one word. Therefore, the move2
instruction (that has 4 operands) needs two words for its
operands.
Take advantage of the larger wordsize in the 64-bit emulator
and pack up to 4 operands into a single word.
|
|
Giving the beam_makeops script access to the external word
size (=the size of instruction words) will allow it to pack
more operands into a word for the 64 bits emulator.
|
|
In the transformation engine in the loader, an is_eq/1 instruction
is currently always preceded by an is_type/1 instruction. Therefore,
save a word and slight amount of time by combining those
instructions into an is_type_eq/2 instruction.

|
The i_jump_on_val_zero/3 and i_select_tuple_arity/3 instructions
were not disassembled correctly.
|
|
|
|
|
|

It would only really work in simple case like:
select_val S=q Fail=f Size=u Rest=* => ...
where all operands for a single instruction where bound to
variables, and not for more complicated cases such as:
i_put_tuple Dst Arity Puts=* | put PutSrc => ...
|
|
There was a version of the BEAM loader and emulator that
had two versions of the fmove/2 instruction, one version
that allocated heap space internally and a newer version that
assumed that a previous test_heap/2 instruction had already
allocated the heap space.
Though the allocating fmove/2 instruction is no longer
supported, some vestiges of it still remains.

erts_debug:instructions/0 is useful for finding which specific
instructions that are not used at all.

Sometimes the beam_bool pass wants to know whether an
y register will be killed by the code that follows and
will do (effectively):
beam_utils:is_killed({y,Y}, Code, L)
When asked to calculate the liveness for an y register,
beam_utils:is_killed/3 will loop forever if the code
includes a receive loop.
Since this rarely occurs, fix the problem in the simplest
and most conservative way.

The AI_V4MAPPED flag is falling out of grace in modern
IPv6 stacks, for security reasons, e.g. FreeBSD do not
document it any longer. The AI_ADDRCONFIG flag have
got unclear semantics on the same OS.
