Bug ID: 45406
Summary: DebugInfo: Missing parameter location on entry to a
function before immediate clobbering
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement

extern int x;
void f1(int i) {
i = x;
}
This has no location for 'i' (the store from 'x' was dead, so it was removed).
It'd be nice to have a location for 'i' on entry to the function, even if it's
immediately clobbered once the first instruction of the function is executed.
