This directory contains gcc in a form that uses "bmake" makefiles.
|
|
This is not the place you want to start, if you want to hack gcc.
|
|
we have included everything here which is part of the source-code
|
|
of gcc, but still, don't use this as a hacking-base.
|
|
|
|
If you suspect a problem with gcc, or just want to hack it in general,
|
|
get a complete gcc-X.Y.Z.tar.gz from somewhere, and use that.
|
|
|
|
Please look in the directory src/gnu/gnu2bmake to find the tools
|
|
to generate these files.
|
|
|
|
Thankyou.
