Comment(by pmichaud):
Replying to [comment:7 whiteknight]:
>One question I have is whether the call "load_bytecode 'foo.pir'" Always
triggers the :load functions and not the :init functions. For a .pbc file
I agree that triggering the :load functions is the expected behavior, but
I would be very very surprised if IMCC were smart enough to determine that
it should trigger :load and not :init after compiling from the
load_bytecode opcode. [...] I would be extremely surprised if
"load_bytecode 'foo.pir'" did not trigger the :init functions.
Prepare to be surprised then, because IMCC (2.10.1) definitely triggers
the :load functions and not the :init ones when invoked via load_bytecode
:-)
{{{
$ cat x.pir
.sub 'first'
say 'first'
.end
.sub 'load' :load
say ':load'
.end
.sub 'init' :init
say ':init'
.end
.sub 'loadinit' :load :init
say ':load :init'
.end
.sub 'main' :main
say ':main'
.end
$ cat y.pir
.sub 'main' :main
load_bytecode 'x.pir'
.end
$ ./parrot y.pir
:load
:load :init
$
}}}
As you can see, the subs marked ":load" are the ones executed -- the one
marked only with ":init" is not executed.
> Also, I thought there was a way to output .pbc files from Parrot PIR
code. If there isn't one, we need to make creating it a high priority.
It was speculated at one point that one could simply write the object
coming back from the PIR compiler to a file and use that. That seems to
work for very simple PIR files, but fails for anything much larger (i.e.,
it didn't work for files generated by nqp-rx).
