Hello,
I have a question about the Parrot FAQ. I hope it's not too off-topic for this
list. The FAQ mentions that "it would be nice to write the Perl to Bytecode
compiler in Perl" and that there is no bootstrap problem.
Does this mean that the perl6 compiler is written in perl5 and it will be

Hmm wouldn't the JIT benifit from a pre knowledge of basic blocks

Oh, sure. But whether the metadata is

Full restart for JIT/i386 is in CVS now.
This implied some changes:
- interpreter has now a jit_info *
- build_asm had a jit_info on the stack, this is currently static, but
will be allocated soon.
- architectures h

I did check in a fix (or part of it) for restarting JIT.
- changed restartable OPs to have jump flag set
- test PC (eax) if zero, stop JIT
This makes all test succeed on i386/linux under JIT too.
Other architectures could follow the scheme of the i386 code, which
shouldn't be too hard. Currently
