We build qemu-x86_64 on LoongArch machine, but got an error,
../linux-user/host/loongarch64/host-signal.h:57:9: error: a label can only be
part of a statement and a declaration is not a statement
uint32_t sel = (insn >> 15) & 0b11111111111;
^~~~~~~~
I think we should define 'sel' before:
/* Detect store by reading the instruction at the program counter. */
switch ((insn >> 26) & 0b111111) {
or
case 0b001110:
{
uint32_t set = ...;
...
}
