Subject: [PATCH] Reduce nesting of parentheses in conditionals generated by
 genattrtab

gcc/ChangeLog:

        * genattrtab.c (write_test_expr): New parameter EMIT_PARENS
        which defaults to true.  Emit an outer pair of parentheses only if
        EMIT_PARENS.  When continuing a chain of && or || (or & or |),
        don't emit parentheses for the right-hand operand.

git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@235536

gcc/arm generates so many parens it hits a bracket depth limited which is
enforced by clang. This reduces the number of parens generated and avoids the
need to increase bracket depth.

Fixes PR toolchain/53178 properly.
