2588 /* For special_memory_operand, there could be a memory operand
inside,
2589 and it would cause a mismatch for constraint_satisfied_p. */
2590 if (UNARY_P (op) && op == extract_mem_from_operand (op))
2591 op = XEXP (op, 0);
the upper code is supposed to only prevent special_memory_constraint, but
mistakenly handled below insn.

Probably related:
struct {
struct {
int b
}
} c;
a(e) { asm("" : : "rm"(e)); }
d() { a(~c.b); }
Flag -O1 required. Goes wrong sometime between 20201021
and 20201022.

Don't extract memory from operand for normal memory constraint.
I'm testing this patch.
