Hi Jiong,
wow you really did it! This is the biggest contribution that the JIT compiler ever had! Thank you very much!
I checked the patch, and it looks good in general, but I have some suggestions. Please add a license block to sljitNativeTILEGX-dis.c, and your copyright line should be before my name (even my name is not important here). These files made only by you, so you really deserve it.
It also seems to me that the disassembler is always enabled (included). For production ready code, this debugging feature might be unnecessary. Would it be possible to conditionally (using compile time defines) enable it?
Sljit uses kernel coding style, including tabs for indentation. I know this task takes time for such a large patch, but would it be possible to change spaces to tabs?
Lastly, your patch is a bit big for a mailing list, so please send its updates to me privately, or open a bug in
http://bugs.exim.org/ and submit them there (we can also continue the discussion there).
Regards,
Zoltan
