#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. */
