It does not crash on linux host but crash on windows host.

I think it is the bug in the front end for windows that fails to create
temporary files.

This is most likely a loongarch64 backend issue where it uses long instead of
host wide int for testing the value of a const_int.

--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I suspect it is this macro which is causing the issue:
/* True if VALUE can be loaded into a register using LU12I.  */

#define LU12I_OPERAND(VALUE) \
  (((VALUE) | ((1UL << 31) - IMM_REACH)) == ((1UL << 31) - IMM_REACH) \
   || ((VALUE) | ((1UL << 31) - IMM_REACH)) + IMM_REACH == 0)

It should either use ULL or use HOST_WIDE_INT_1U instead of 1UL.

--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
It might also be:
#define IMM16_OPERAND(VALUE) \
  ((unsigned HOST_WIDE_INT) (VALUE) + 0x8000 < 0x10000)
