Hi,
I'm in the process of porting dyncall (http://dyncall.org) to Plan9,
and I
was wondering if there are any documents about the calling
convention used
by Plan9 - specifically for x86, for starters. I was unable to find
any at
the time of writing, and well, hoped that it would be similar to the
SystemV calling convention(s) used by the *BSDs or Linux, etc., but
that
doesn't seem to be the case.
The only information I found so far, is, that most of the compiled
Plan9
functions don't seem to have any prologue/epilogue, however, this
assumption might be wrong (maybe I didn't get how Plan9 works on the
machine-level, so far).
I hope you don't mind me asking, but what do the prologue and epilogue
normally do? With only a basic knowledge of C and assembler, I can't
imagine what they might be for. Are they anything to do with dynamic
linking?
I'm still new to Plan9, but it's quite mind-opening to discover
certain
aspects of the OS - especially after getting so (too) used to Unix/
Windows
OS design decisions and accepting them as the normal/right way to do
things...
Oh tell me about it, I'm finding
Thanks,
