- Subject: alternative for bootstrapping non-C frontends
after reading mails on this list about people having to jump through
hoops to bootstrap the ADA front-end on non-mainstream architectures,
I had an idea for bootstrapping GCC that I would like to present and ask
your feedback upon...
Would it be possible to distribute RTL releases of the non-C frontends
and compile those as part of stage1 bootstrapping?
I understand that it is impossible to distribute binaries for every
possible architecture + os + runtimelibs... distributing an RTL version
of the compilers would not have this problem, as it is platform-independent.
Let me clarify:
If the frontends could be compiled to RTL, and some external
representation of that platform-independent representation of the
programs be written to files (eg. .rtl instead of .o files), then one
could get away with bootstrapping the C frontend, and the backend for
the platform, and then compile the .rtl files to .o files, and link
those to obtain a working frontend. This would remove the need to find
an existing ADA compiler for the target platform, or the need to go
through the process of building a cross-compiler.
This process would simplify bootstrapping for compilers that are not
written in C.
I don't know if this has been proposed before, and if it has, I hope
this is not bait for a holy war on the list...
