Note:Since the control register is divided into 32-bit and 64-bit, but the access instruction is not distinguished. So GCC renames the control instructions when implementing intrinsics.

Take the csrrd instruction as an example, built-in functions are implemented as follows:

-
__builtin_loongarch_csrrd_w  // When reading the 32-bit control register use.
-__builtin_loongarch_csrrd_d  // When reading the 64-bit control register use.
-

For the convenience of use, the built-in functions are encapsulated, the encapsulated functions and __drdtime_t, __rdtime_t are defined in the larchintrin.h. So if you call the following function you need to include larchintrin.h. 

typedef struct drdtime{
-       unsigned long dvalue;
-       unsigned long dtimeid;
-} __drdtime_t;
-
-typedef struct rdtime{
-       unsigned int value;
-       unsigned int timeid;
-} __rdtime_t;
-

-__rdtime_t  __rdtimel_w (void)
-__rdtime_t  __rdtimeh_w (void)

-void __cacop_d (imm0_31, unsigned long, imm_n2048_2047)
-unsigned int  __cpucfg (unsigned int)
-void __asrtle_d (long int, long int)
-void __asrtgt_d (long int, long int)
