Macro Assembler
4.3.8.17 FNROOT
This directive tells the assembler that a function is a root function and thus forms the root of a call
graph. It could either be the C main() function or an interrupt function. For example, the C main
module produce the directive:
4.3.8.18 IF, ELSIF, ELSE and ENDIF
These directives implement conditional assembly. The argument to IF and ELSIF should be an
absolute expression. If it is non-zero, then the code following it up to the next matching ELSE,
ELSIF or ENDIF will be assembled. If the expression is zero then the code up to the next matching
ELSE or ENDIF will be skipped.
nate the conditional assembly block. Example:
In this example, if ABC is non-zero, the first jmp instruction will be assembled but not the second or
third. If ABC is zero and DEF is non-zero, the second jmp will be assembled but the first and third
will not. If both ABC and DEF are zero, the third jmp will be assembled. Conditional assembly blocks
may be nested.
4.3.8.19 MACRO and ENDM
These directives provide for the definition of macros. The MACRO directive should be preceded by
the macro name and optionally followed by a comma-separated list of formal parameters. When the
macro is used, the macro name should be used in the same manner as a machine opcode, followed
by a list of arguments to be substituted for the formal parameters.
At an ELSE the sense of the conditional compilation will be inverted, while an ENDIF will termi-
For example:
FNROOT _main
IF ABC
ELSIF DEF
ELSE
ENDIF
;macro: storem
;args: arg1 - the NAME of the source variable
;
goto aardvark
goto denver
goto grapes
arg2 - the literal value to load
