+#define ASSEMBLER_DIALECT AVR_ENHANCED
+/* If your target supports multiple dialects of assembler language
+ (such as different opcodes), define this macro as a C expression
+ that gives the numeric index of the assembler language dialect to
+ use, with zero as the first variant.
+
+ If this macro is defined, you may use constructs of the form
+ `{option0|option1|option2...}' in the output templates of patterns
+ (*note Output Template::.) or in the first argument of
+ `asm_fprintf'. This construct outputs `option0', `option1' or
+ `option2', etc., if the value of `ASSEMBLER_DIALECT' is zero, one
+ or two, etc. Any special characters within these strings retain
+ their usual meaning.
+
+ If you do not define this macro, the characters `{', `|' and `}'
+ do not have any special meaning when used in templates or operands
+ to `asm_fprintf'.
+
+ Define the macros `REGISTER_PREFIX', `LOCAL_LABEL_PREFIX',
+ `USER_LABEL_PREFIX' and `IMMEDIATE_PREFIX' if you can express the
+ variations in assembler language syntax with that mechanism.
+ Define `ASSEMBLER_DIALECT' and use the `{option0|option1}' syntax
+ if the syntax variant are larger and involve such things as
+ different opcodes or operand order. */
