6.60.22.6 Basic PowerPC Built-in Functions Available on ISA 3.1

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.

vector signed __int128 vsx_xl_sext (signed long long, signed char *);

vector signed __int128 vsx_xl_sext (signed long long, signed short *);

vector signed __int128 vsx_xl_sext (signed long long, signed int *);

vector signed __int128 vsx_xl_sext (signed long long, signed long long *);

vector unsigned __int128 vsx_xl_zext (signed long long, unsigned char *);

vector unsigned __int128 vsx_xl_zext (signed long long, unsigned short *);

vector unsigned __int128 vsx_xl_zext (signed long long, unsigned int *);

vector unsigned __int128 vsx_xl_zext (signed long long, unsigned long long *);

Load (and sign extend) to an __int128 vector, as if implemented by the ISA 3.1 lxvrbx lxvrhx lxvrwx lxvrdx instructions.

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

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 *);

Truncate and store the rightmost element of a vector, as if implemented by the ISA 3.1 stxvrbx stxvrhx stxvrwx stxvrdx instructions.
