Probably related to Bug 1173.
void main() {
int x;
asm {
mov x, x.max;
}
}
The above code compiles. However, if you replace "x.max" with "int.max", DMD complains about "ptr expected". Replace it with "typeof(x).max" or add brackets around the expression and DMD complains about "nops expected".
This can be worked around by using a temporary or constant.

Using the .ptr property of an array doesn't work either.
Neither does &arr.

Currently it's not specified but can be supported since asm operands with dot exp must be evaluable by CTFE to a const. Changing importance from reject-valid to enhancement.
