When trying to get this entry to work for modern systems I ended up
replacing some macros with what they translated to. This meant that it
did not look as close to what the original entry looked like.
There was another change as well in this commit. The variable that is
the file to open was changed to a FILE * instead of an int. Although it
did not crash after the change I made when trying to open the file (see
below for why this was done) it's not strictly correct either in modern
systems (and maybe not in older systems either though it clearly
worked).
Now as for why the fix to being able to open the file: it's because at
the time I was trying to get it to work with modern systems even though
the author stated that it was designed for i386 linux. Doing this proved
possible with a number of other entries but in order for it to even get to
that point this change was necessary. According to Yusuke Endoh, it did
work with an emulator so that was not strictly necessary but I did not
know this at the time and it seems better that at least it can open the
file even if it won't completely work due to the way it is designed. It
seems better too as it might help provide a way to get a version for
64-bit systems.
The thanks-for-fixes.md and bugs.md files were updated on account of
these changes. The bugs.md file also includes why it was changed when
the entry is designed for i386 linux: besides the fact that I fixed the
supplementary program that did not work at all. It seems that, according
to Yusuke, that both works in an emulator but this way at least one can
enjoy the supplementary program in modern systems too and the entry
itself is a bit more correct.
The bug status of this entry changed as well. It now has both INABIAF
but also asking for alternate code. Why this is is explained in the
file: it does indeed seem to not make sense but the rationale is
explained there.
The author stated this directly. It is noted in the bugs.md file and the
README.
I also included a suggested change by Yusuke Endoh. This is not
necessary for compilers that support -Wl,-z,execstack but not all
compilers do (though the only one I've found that has this problem is
macOS which it won't work under anyway just like -m32 won't which we
also now use).
Added the 'more portable' version by the author. This does not compile
at least under 64-bit linux (not macOS either though of course it
wouldn't work in macOS as if you look at the code you see hardcoded
paths for linux ld-linux.so).
I note that there's a de-obfuscated version on the author's page for the
entry which might give some clues. I might look at it in the future but
it appears that unless someone can provide a 64-bit linux version this
will be one of the entries (now far fewer with many fixes made) that
simply no longer work.
This thus completes for now 2001/bellard even with disappointing
circumstances.
This still crashes and may very well not work even if it doesn't but I
cannot determine that. I just fixed the initial segfault when opening
the file. I believe it will take much debugging, a 32-bit system to test
it on and also a knowledge of the ELF format. There might be other
things but I believe those are the minimum requirements.
I did fix the supplementary program bellard.otccex.c so it does not
segfault and seemingly it works too (I didn't really evaluate that the
output is correct but it does process the args anyway).
I updated bugs.md to note that this entry does not work and any help
would be appreciated.
We we move 1988-2004 entries from all of a year's winning entries
in a single directory to each winner being in their own sub-directory
under the given year directory.
