From: Pan Li <pan2...@intel.com>
The rv32 doesn't support __uint128, and then we will have
error like below during test.
error: '__int128' is not supported on this target.
Thus, we disable the uint128_t related test when rv32.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sat/sat_arith.h: Add xlen check for
uint128_t.
* gcc.target/riscv/sat/sat_u_mul-run-1-u16-from-u128.c: Enable
run test for rv64 only.
* gcc.target/riscv/sat/sat_u_mul-run-1-u32-from-u128.c: Ditto.
* gcc.target/riscv/sat/sat_u_mul-run-1-u64-from-u128.c: Ditto.
* gcc.target/riscv/sat/sat_u_mul-run-1-u8-from-u128.c: Ditto.
