Since 0x296318e8 is data, we need to investigate where we jumped.
The backtrace looks normal, so I think you're getting anomalous jumps when
optimizing long_richcompare.

Line 114 is lookup jump table. But not check offset range.
So if r2 is out of range (in default case). Refer out of table.

-O0 generate collect code. I think optimizing bug.

I compiled this inline assembler functions.

 "clrpsw i\n\t"
 "btst %3, %1.b\n\t"

 :"ri"(nr & 7):"cc");

I got this result. The result which isn't expected.
%2 and %3 is same...
rx-elf-gcc -Os
mvfc psw, r1
clrpsw i
btst r1, [r2].b
bset r1, [r2].b

char dummy;
int foo(char *a, unsigned int b, long long c)

 ret = bar(p, a, b, c);

 return ret;
}

I think it code miss compile and generate invalid rtx.
