[PULL 16/75] target/loongarch: Remove target_ulong use in gdb_write_register handler

Posted by Philippe Mathieu-Daudé 3 months, 3 weeks ago

ldq_le_p() returns a uint64_t type, big enough to also hold
ldl_le_p() return value. If we were building for a 32-bit
LoongArch target, ldq_le_p() would not fit in target_ulong.
Better stick to plain uint64_t.
