<pre>This code:
char a[] = {1, 1, 1};
char b = 1;
int c;
static int d;
e() {
char *f = &a[2];
char *g = &b;
char **h = c;
if (g != (*h = f))
d = 70;
}
i() { fn3(d); }
Compiled like this:
clang --target=arm-arm-none-eabi -mcpu=cortex-m0plus -c test.c -O3 -c
Gives me this:
Operand not processed?
t21: ch = br t23, BasicBlock:ch<if.then 0x82b168>
UNREACHABLE executed at ../lib/CodeGen/SelectionDAG/LegalizeTypes.cpp:476!
