/* 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. */
