Hello, I want to examine yhc bytecode, but Robert Dockins's library (http://www.eecs.tufts.edu/~rdocki01/yhc-bytecode.html) complains of a "Bad version". Are there any alternatives, other than doing it manually using a hex editor? Thanks. -- Kartik Vaddadi.

Hi Kartik,
yhc -help gives you:

-bcodemem show B code after heap usage analysis (default=off)
-bcodeflatten show B code after flattening (default=off)
-bcoderel show B code after converting to relative jumps
(default=off)
Running yhc Main.hs -bcodecompile
Compiling Main ( Main.hs )

The bytecode library should work, I'll raise a bug.
Thanks

Can you give some more details about the problem? What architecture/ OS are you on? How did you compile the bytecode lib? How did you invoke it? Can you provide a small hbc file that causes the problem for you?

Ah. Well, this is the problem. The bytecode library expects exactly version 1.9 of the bytecode set. As far as I was aware, that was the latest version. Has the bytecode set been version bumped recently? It is to do with x64? I've been busy with other things recently and haven't been following Yhc development as closely as I'd like.
test.hs:
main = print (3 + f 2) f x = x

import Yhc.Bytecode.Version_1_9
main = (readFile "g:\\projects\\debugger\\Main.hbc") >>= readLogicalModule >>= print
That looks about right.

Bad version

No problem. This is as good a list as any to discuss bugs in this library, since I don't have a separate project space for it. And thanks for this bug report. I'll see what I can do about getting this fixed.
Thanks for your time.

Hi

Tom, Neil? Any word on this?
No idea. Will give Tom a gentle prod tomorrow. Once we have the bytecode library in the Yhc darcs repo, we might want to add some basic tests to the Bytecode library to be executed with buildbot. Ditto for the Yhc.Core library. Thanks Neil

It's very likely, from time to time it becomes necessary to add extra information to the bytecode. I'm not sure what it was for though ... though nothing to do with x64 certainly ... Thanks Tom

Hummm... so apparently, the problem here is that I am an idiot. :( The bootstrap .hbc files in the Yhc distribution have minor version 9 and the versions generated by the compiler have minor version 10. I never noticed because I was using the API to generate bytecode more than to read it, and the runtime accepted my files with minor ver 9. I clearly did all my initial read testing agains the 'bootstrap' versions of the Yhc libraries. Ugh. The darcs history shows me that the minor version of the bytecode has been 10 since Yhc was under darcs control, so that's clearly the correct version number. Does anyone happen to know what the differences between versions 9 and 10 are? What version does the data sheet at 'src/compiler98/Bytecode/data/bytecode.xml' describe?
Thanks
Tom

Hi
The bootstrap .hbc files in the Yhc distribution have minor version 9 and the versions generated by the compiler have minor version 10.
Do we still need the bootstrap .hbc files? Isn't this just a hangover from before we could really build Yhc libraries properly on all platforms?
Does anyone happen to know what the differences between versions 9 and 10 are? What version does the data sheet at 'src/compiler98/Bytecode/data/bytecode.xml' describe?
I suspect its version 10, but don't really know. I guess the best way to find the differences are to look at the C code that reads the bytecodes, it can't be too different between the two give that it translates between them at runtime. I suspect its only additions of new bytecodes. Thanks Neil
