- Subject: Where the languages meet...
After reading the internals of gcc wikibooks some questions come up.
So, gcc has front end for C, C++, java, fortran, etc..
All these languages have a frontend which parse into AST and then
GIMPLE which is converted to RTX and then assembly. Now, my guess is
that GIMPLE is the _common_ ground for all languages. No matter which
language, all will go through GIMPLE, so if I wished to implement some
language analysis / optimizations, I should do it in GIMPLE to be able
to implement in one go the optimization for all languages, right?
Is there any formal syntax/semantics for GIMPLE? Or the SIMPLE paper
is the only thing with this stuff? Any reference to the differences
between GIMPLE and SIMPLE?
