We have had several cgen ports, some of them public, where
parentheses were part of the assembly operand syntax.  They
work fine.  You may need to add this line in gas/config/tc-TARGET.h
to help out:

/* [...] uses '(' and ')' as punctuation in addressing mode syntax.  */
#define RELAX_PAREN_GROUPING

Dave is right about there being some order-sensitive effects
in cgen inputs, but I prefer to avoid relying on them.
