/* Note on the reason of using 'X7' instead of 'W7' here:
Using 'X7' makes sure the test works in the big-endian mode.
According to PCS rules B.4 and C.10, the size of float_int is rounded
to 8 bytes and prepared in the register X7 as if loaded via LDR from
the memory, with the content of the other 4 bytes unspecified. The
test framework will only compare the 4 relavent bytes. */
