Macro Assembler
4.3.8.17 FNSIZE
The FNSIZE directive informs the linker of the size of the local variable and argument area associ-
ated with a function. These values are used by the linker when building the call graph and assigning
addresses to the variable and argument areas. This directive takes the form:
The named function has a local variable area and argument area as specified, for example
means the function fred() has 10 bytes of local variables and 5 bytes of arguments. The function
name arguments to any of the call graph associated directives may be local or global. Local functions
are of course defined in the current module, but most be used in the call graph construction in the
same manner as global names.
4.3.8.18 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:
4.3.8.19 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.
terminate the conditional assembly block. Example:
At an ELSE the sense of the conditional compilation will be inverted, while an ENDIF will
