Macro Assembler
4.3.8.11 FNADDR
This directive tells the linker that a function has its address taken, and thus could be called indirectly
through a function pointer. For example
tells the linker that func1() has its address taken.
4.3.8.12 FNARG
The directive
tells the linker that evaluation of the arguments to function fun1 involves a call to fun2, thus the
memory argument memory allocated for the two functions should not overlap. For example, the C
function calls
will generate the assembler directive
thereby telling the linker that bill() is called while evaluating the arguments for a call to fred().
4.3.8.13 FNBREAK
This directive is used to break links in the call graph information. The form of this directive is as
follows:
and is automatically generated when the interrupt_level pragma is used. It states that any calls to
fun1 in trees other than the one rooted at fun2 should not be considered when checking for functions
that appear in multiple call graphs. Fun2() is typically intlevel0 or intlevel1 in compiler-generated
code when the interrupt_level pragma is used. Memory for the auto/parameter area for a fun1 will
only be assigned in the tree rooted at fun2.
FNADDR _func1
FNARG fun1,fun2
fred(var1, bill(), 2);
FNARG _fred,_bill
FNBREAK fun1,fun2
