Hi All,
I was wondering if there is a grammar definition for
the
Plan9 C compiler (lex and yacc/flex and bison)? Any
documents for the compiler grammar, anywhere?

/sys/src/cmd/cc/cc.y, cc.h, etc. No lex used.
/sys/doc/compiler.ps describes it.

/sys/src/cmd/cc/cc.y (you might need the Plan 9 yacc)
the lexical analyser is hand written.
/sys/src/cmd/cc/lex.c
/sys/src/cmd/cc/mac.c (includes /sys/src/cmd/cc/macbody) for the built-in preprocessor
in fact, lex.c includes the compiler main program and some other little functions,
so the lexical analyser proper is smaller
