Deep Scan Variable on existing structures

[Frago9876543210]

I got binary file with debugging information and would like to find all cross-references to an existing field, that added automatically during the first analysis

Could you demonstrate an example with that problem? I'm not sure that I correctly get it.

If it is related to not being able to scan struct pointers that only declared but not defined then you may find useful setting scan_any_type = False in $IDA_DIR/cfg/HexRaysPyTools.cfg

Let's look at the real case. This program is compiled with debugging information and all types are already known after analysis. However, option "deep scan variable" can't find all xrefs to Foo.x until you decompile all functions that reletated to it

#include <cstdio>

class Foo {
public:
	int x, y, z;

	Foo(int x, int y, int z) : x(x), y(y), z(z) {} //xref to Foo.x

	void plus(int x1) {
		this->x += x1; //xref to Foo.x
	}

	void minus(int x1) {
		this->x -= x1 * 2; //xref to Foo.x
	}
};

int main() {
	Foo foo = Foo(10, 20, 30);
	foo.plus(10);
	foo.minus(10);

	printf("%d, %d, %d\n", foo.x, foo.y, foo.z); //xref to Foo.x

	return 0;
}
