- Subject: rtl semantics
Hi,
I just read all the gcc internals manual.
I have trouble with the contextual polymorphic
nature of rtl objects.
In h8300.md, there is:
(define_attr "cpu" "h8300,h8300h"
(const (symbol_ref "cpu_type")))
yet in gccint.info, const should have a machine mode: (const:M EXP)
Do rtl keywords have a variable meaning, depending on the context
where they're used? Is there other languages similar to rtl i could
learn from? (scheme?)
