Summary: llvm-gcc fails to emit volatile for volatile array
struct argument?
Product: new-bugs
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: new bugs
AssignedTo: [email protected]

Case here:
struct X {
int a;
int b;
int c;
};
int foo(volatile struct X x[100]) {
int i;
int r = 0;
for (i = 0; i < 100; ++i)
r += x[i].a;
}
With ToT, in the emitted ll code, the volatile for LoadInst of x[100] is lost.
