Subject: target/loongarch: Remove target_ulong use in gdb_write_register handler
X-Git-Tag: v10.2.0-rc1~61^2~61
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=7f306758fb83f1b64d02647171d5f65fc157ac25;p=thirdparty%2Fqemu.git

target/loongarch: Remove target_ulong use in gdb_write_register handler

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.
