=head1 TITLE
Parrot JIT i386/gcc
=head1 VERSION
=head2 CURRENT
14.02.2003 by Leopold Toetsch
=head1 ABSTRACT
This PDD describes the i386 gcc JIT implementation.
=head1 DESCRIPTION
JIT i386/gcc is a combination of unrolled assembly instructions and
the Computed CGoto Prederefed (CGP) run loop. For branch instructions
the function implementation in the standard core is called.
Another difference of JIT/i386 is, that most vtable functions are
JITed instructions which use register mappings.
For a better understanding of the control flow between these basically
3 run loop cores, an example shows the gory details.
=head1 EXAMPLE
Given the following PASM program, the right 3 colums show, where which
opcode gets executed:
PASM JIT ops Normal CGP ops
(call cgp_core) (jmp back)
set I0, 10 set_i_ic
print I0 (call) print_i
print "\n" print_sc
bsr inc (call) bsr_ic cpu_ret
end (jmp) HALT end (ret)
end (ret)
inc:
inc I0 inc_i
new P0, .PerlString new_p_ic
set P0, I0 set_p_i
print P0 (call) print_p
print "\n" print_sc
ret (call) ret cpu_ret
=head2 Startup sequence
In B<runops_jit> a prederefed copy of the opcode stream is built by
B<init_prederef>. Then B<build_asm> generates the assembler code
seqence as usual. This generated code (shown as B<runops_jit> in
B<ddd>) then is executed.
Generate minimal stack frame, save %ebx
0x812c510 <jit_func>: push %ebp
0x812c511 <jit_func+1>: mov %esp,%ebp
0x812c513 <jit_func+3>: push %ebx
Get the program counter to %ebx
0x812c514 <jit_func+4>: mov 0xc(%ebp),%ebx
Push B<interpreter> and B<(opcode_t*) 1> and call B<cgp_core>
0x812c517 <jit_func+7>: push $0x8113db8
0x812c51c <jit_func+12>: push $0x1
0x812c521 <jit_func+17>: mov $0x1,%eax
0x812c526 <jit_func+22>: call 0x80b5830 <cgp_core>
In B<cgp_core> all callee saved registers are saved.
0x80b5830 <cgp_core>: push %ebp
0x80b5831 <cgp_core+1>: mov %esp,%ebp
0x80b5833 <cgp_core+3>: sub $0xdc,%esp
0x80b5839 <cgp_core+9>: lea 0x8(%ebp),%eax
0x80b583c <cgp_core+12>: push %edi
0x80b583d <cgp_core+13>: push %esi
0x80b583e <cgp_core+14>: push %ebx
In B<%eax> the init flag is set to B<-1>
0x80b583f <cgp_core+15>: mov %eax,0xfffffff
The parameter B<*cur_op> (the program counter) is put into B<%esi> and ...
0x80b5842 <cgp_core+18>: mov 0x8(%ebp),%esi
0x80b5845 <cgp_core+21>: test %esi,%esi
0x80b5847 <cgp_core+23>: jne 0x80b5853 <cgp_core+35>
0x80b5849 <cgp_core+25>: mov $0x810ca60,%eax
0x80b584e <cgp_core+30>: jmp 0x80bb470 <cgp_core+23616>
... compared to B<1>
0x80b5853 <cgp_core+35>: cmp $0x1,%esi
0x80b5856 <cgp_core+38>: jne 0x80b5860 <cgp_core+48>
and, if yes, the program jumps to the return address of above function
call, i.e. it jumps back again to JIT code.
0x80b5858 <cgp_core+40>: jmp *0x4(%ebp)
Back again in JIT code, the init flag is checked
0x812c52b <jit_func+27>: test %eax,%eax
0x812c52d <jit_func+29>: jne 0x812c536 <jit_func+38>
... and if zero, the function would be left.
[ 0x812c52f <jit_func+31>: pop %ebx ]
[ 0x812c531 <jit_func+33>: mov %ebp,%esp ]
[ 0x812c533 <jit_func+35>: pop %ebp ]
[ 0x812c535 <jit_func+37>: ret ]
When coming from the init sequence program flow continues with
checking the B<resume_offset> and jumping to the desired instruction
0x812c536 <jit_func+38>: mov %ebx,%eax
0x812c538 <jit_func+40>: sub $0x400140c0,%eax
0x812c53e <jit_func+46>: mov $0x812c4a8,%edx
0x812c543 <jit_func+51>: jmp *(%edx,%eax,1)
B<set I0, 10> and save_registers
0x812c546 <jit_func+54>: mov $0xa,%ebx
0x812c54b <jit_func+59>: mov %ebx,0x8113db8
Now non-JITed code follows, get the address from the prederefed
op_func_table and call it:
0x812c551 <jit_func+65>: mov $0x812ac0c,%esi
0x812c556 <jit_func+70>: call *(%esi)
inline op print(in INT) {
printf(INTVAL_FMT, (INTVAL)$1);
goto NEXT();
}
where the B<goto NEXT()> is a simple:
0x80b5b49 <cgp_core+793>: jmp *(%esi)
op print(in STR) {
...
goto NEXT();
}
As the last instruction of the non JITed code sequence is a branch,
this is not executed in CGP, but the opcode:
inline op cpu_ret() {
#ifdef __GNUC__
# ifdef I386
asm("ret")
is executed. This opcode is patched into the prederefed code stream
by Parrot_jit_normal_op at the end of a non JITed code sequence. This
returns to JIT code again, where the next instruction gets called as a
function in the standard core ...
0x812c558 <jit_func+72>: push $0x8113db8
0x812c55d <jit_func+77>: push $0x400140dc
0x812c562 <jit_func+82>: call 0x805be60 <Parrot_bsr_ic>
0x812c567 <jit_func+87>: add $0x8,%esp
... and from the return result in B<%eax> the new code position in JIT
is calculated and gets jumped to
0x812c56a <jit_func+90>: sub $0x400140c0,%eax
0x812c570 <jit_func+96>: mov $0x812c4a8,%edx
0x812c575 <jit_func+101>: jmp *(%edx,%eax,1)
Now in the subroutine B<inc>:
0x812c580 <jit_func+112>: mov 0x8113db8,%ebx
0x812c586 <jit_func+118>: inc %ebx
Save register and arguments and call B<pmc_new_noinit>
0x812c587 <jit_func+119>: push %edx
0x812c588 <jit_func+120>: push $0x11
0x812c58d <jit_func+125>: push $0x8113db8
0x812c592 <jit_func+130>: call 0x806fc60 <pmc_new_noinit>
put the PMC* into parrots registeer
0x812c597 <jit_func+135>: mov %eax,0x8113fb8
and prepare arguments for a VTABLE call
0x812c59d <jit_func+141>: push %eax
0x812c59e <jit_func+142>: push $0x8113db8
0x812c5a3 <jit_func+147>: mov 0x10(%eax),%eax
0x812c5a6 <jit_func+150>: call *0x18(%eax)
0x812c5a9 <jit_func+153>: add $0x10,%esp
0x812c5ac <jit_func+156>: pop %edx
and another one
0x812c5ae <jit_func+158>: push %edx
here with the mapped register in B<%ebx>, push B<I0>, the PMC and the
interpreter
0x812c5af <jit_func+159>: push %ebx
0x812c5b0 <jit_func+160>: mov 0x8113fb8,%eax
0x812c5b6 <jit_func+166>: push %eax
0x812c5b7 <jit_func+167>: push $0x8113db8
and call the vtable
0x812c5bc <jit_func+172>: mov 0x10(%eax),%eax
0x812c5bf <jit_func+175>: call *0xdc(%eax)
0x812c5c5 <jit_func+181>: add $0xc,%esp
0x812c5c8 <jit_func+184>: pop %edx
As this ends the JITed section, used registers are saved back to
parrots register
0x812c5ca <jit_func+186>: mov %ebx,0x8113db8
and again the code in B<cgp_core> gets called
0x812c5d0 <jit_func+192>: mov $0x812ac48,%esi
0x812c5d5 <jit_func+197>: call *(%esi)
which after executing the B<print> returns back here in JIT, where the
B<ret> is called
0x812c5d7 <jit_func+199>: push $0x8113db8
0x812c5dc <jit_func+204>: push $0x40014118
0x812c5e1 <jit_func+209>: call 0x805d5e0 <Parrot_ret>
0x812c5e6 <jit_func+214>: add $0x8,%esp
and from the returned PC a JIT address is calculated, which gets
executed then:
0x812c5e9 <jit_func+217>: sub $0x400140c0,%eax
0x812c5ef <jit_func+223>: mov $0x812c4a8,%edx
0x812c5f4 <jit_func+228>: jmp *(%edx,%eax,1)
Now at the B<end> opcode, the CGP code for HALT() gets jumped to:
0x812c578 <jit_func+104>: mov $0x80b5877,%esi
0x812c57d <jit_func+109>: jmp *%esi
which is:
inline op end() {
HALT();
}
or, set return result
0x80b8b6f <cgp_core+13119>: xor %eax,%eax
...
and clean up stack frame and ret:
0x80bb470 <cgp_core+23616>: lea 0xffffff18(%ebp),%esp
0x80bb476 <cgp_core+23622>: pop %ebx
0x80bb477 <cgp_core+23623>: pop %esi
0x80bb478 <cgp_core+23624>: pop %edi
0x80bb479 <cgp_core+23625>: mov %ebp,%esp
0x80bb47b <cgp_core+23627>: pop %ebp
0x80bb47c <cgp_core+23628>: ret
This returns after the position, where B<cgp_core> was called during
the init sequence, but now the return value B<%eax> is zero and the..
0x812c52b <jit_func+27>: test %eax,%eax
0x812c52d <jit_func+29>: jne 0x812c536 <jit_func+38>
0x812c52f <jit_func+31>: pop %ebx
0x812c531 <jit_func+33>: mov %ebp,%esp
0x812c533 <jit_func+35>: pop %ebp
0x812c535 <jit_func+37>: ret
... whole story ends here, we are back again in B<runops_jit>.
So this is rather simple once it gets going.
=head1 BUGS
The register <%edx> above was preserved over the vtable calls, though
it's unused. The floating point registers do not get saved to
parrots, this assumes, that external routines do preserve the FP stack
pointer and don't use more the 4 floating point registers at once.
