Internal code of GCC G77 (questions)

Hello :)


I am working on G77/GCC source code. I am doing some transformation
for my perso nal research.but before modify GCC code I need to
understand how it works. I have already understood the whole struct
of the compilation, which functions are called and when, but some
things are still missing to me and are hard to understand for me. So
I would apreciate some help :)


here are my requests:
( it's purely internal code ... )


- what is "obstack" ??
( I don't even know what it means in english .. I am french :)


- what is bytecode ?
very often, the compiler is using a different way, in case of
byte_code is asked , but I don't know what it is.


- Is there place where I can find information about internal code of
GCC and G77 . I know that there are some info in gcc-info.* and README
file, but maybe there is a Web about internal code of GCC (maybe I'm
dreaming .... :)


Well, any help would be great :))


And if anybody is trying to understand how G77 or GCC work, I am ready
to share information ...


                                                Thanks Already
