Dang, ignore my previous because this code is a little different.
+ __asm volatile("lw %0, 0(%1)" : "=r"(rv) : "d"(addr));
"d" is listed as "General-purpose integer register" in the gcc docs.
Does the new code pass the full 64-bits of addr in when compiled on an
ABI where an int is 32-bits even though a full register is 64-bits?
