Optlink Contribution

[Jonathan Marler via Digitalmars-d]

I'm attempting to fix 
https://issues.dlang.org/show_bug.cgi?id=4831.  I've been 
debugging the optlink assembly and getting familiar with the 
code.  I have a couple questions though:

1. If I have any questions in the future about optlink who and 
where do I ask these questions? For now I'm posting to this forum 
because I'm not sure where else to send them.

2. Why are the assembly labels in this format: L<number>$?  I ask 
because I changed the labels for some functions so when I stepped 
through the assembly I had a better idea of what the code was 
doing.  So I'm not sure if I should leave the new labels or go 
back to the old L<number>$ labels.

3. Is there any documentation for developers who would like to 
contribute to optlink?  I'd like to make sure I'm following any 
style rules or guidelines.

Any information about developing for optlink would be helpful.  I 
haven't found much information online.  Thanks for any help, I'd 
like to start contributing to the D tools, its a crime to let all 
these bugs live on for so long when they are making adopting this 
language a hindrence for others.
