The basic built-in functions described in this section are available on the PowerPC family of processors starting with ISA 3.1. Unless specific options are explicitly disabled on the command line, specifying option `-mcpu=power10` has the effect of enabling all the same options as for `-mcpu=power9`.

The following built-in functions are available on Linux 64-bit systems that use a future architecture instruction set (`-mcpu=power10`):

unsigned long long int

__builtin_cfuged (unsigned long long int, unsigned long long int)

Perform a 64-bit centrifuge operation, as if implemented by the `cfuged`

instruction.

unsigned long long int

__builtin_cntlzdm (unsigned long long int, unsigned long long int)

Perform a 64-bit count leading zeros operation under mask, as if implemented by the `cntlzdm`

instruction.

unsigned long long int

__builtin_cnttzdm (unsigned long long int, unsigned long long int)

Perform a 64-bit count trailing zeros operation under mask, as if implemented by the `cnttzdm`

instruction.

unsigned long long int

__builtin_pdepd (unsigned long long int, unsigned long long int)

Perform a 64-bit parallel bits deposit operation, as if implemented by the `pdepd`

instruction.

unsigned long long int

__builtin_pextd (unsigned long long int, unsigned long long int)

Perform a 64-bit parallel bits extract operation, as if implemented by the `pextd`

instruction.

void vec_xst_trunc (vector signed __int128, signed long long, signed short *);

void vec_xst_trunc (vector signed __int128, signed long long, signed int *);

void vec_xst_trunc (vector signed __int128, signed long long, signed long long *);

void vec_xst_trunc (vector unsigned __int128, signed long long, unsigned char *);

void vec_xst_trunc (vector unsigned __int128, signed long long, unsigned short *);

void vec_xst_trunc (vector unsigned __int128, signed long long, unsigned int *);

void vec_xst_trunc (vector unsigned __int128, signed long long, unsigned long long *);
