[aspectc-user] how to match line with AspectC (ex : loop "for")

[Stefan Marr]

Hi,

an advice directly on a specific language construct is not possible as  
far as I know.

But if I read the language reference correctly, you might give  
"within()" a try. Actually, its only a guess on what you like to  
achieve.

You cannot capture all similar loops with this, but at least you will  
be able to advice fct() if it is in the lexical body of somefunction()

void somefunction() {
	for(i=0;i<count;i++) { fct(); }
}

advice call("% fct()") && within("void somefunction()") : around() {
	// this is similar to cflow, but matches hopefully
	// only on calls lexically in the body of somefunction()
}

Totally unrelated:

Is there a way to match macros?

In the Lua VM there is a handy macro:
#define GET_OPCODE(i)	(cast(OpCode, ((i)>>POS_OP) & MASK1(SIZE_OP,0)))

and for profiling it would be great if I could write an advice like  
this:

advice call("% GET_OPCODE(...)") && within("void luaV_execute  
(lua_State*, int)") && args(Instruction)
: before(Instruction i) {
	Profiler_add_bytecode(i);
}

Best regards
Stefan
