Bug ID: 105798
Summary: Add new -Wshadow for data member
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: tromey at gcc dot gnu.org
Target Milestone: ---
While refactoring gdb -- changing a function to a method --
I accidentally introduced a self-assign, because the function
used local variables that had the same name as the class members.
gdb uses -Wshadow=local... I don't recall why but it seems like
it would be nice to have a level between 'local' and 'global'
so we could prevent locals from shadowing class members but
still not care about globals.
Test case:
struct x {
int f;
int y(int x) {
int f = x;
return f;
}
};
This warns with -Wshadow but not -Wshadow=local.
