7.13.23.6 Basic PowerPC Built-in Functions Available on ISA 3.1 ¶

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

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

Built-in Function:unsigned long long__builtin_cfuged(unsigned long long, unsigned long long) ¶

Perform a 64-bit centrifuge operation, as if implemented by thecfuged instruction.

Built-in Function:unsigned long long__builtin_cntlzdm(unsigned long long, unsigned long long) ¶

Perform a 64-bit count leading zeros operation under mask, as ifimplemented by thecntlzdm instruction.

Built-in Function:unsigned long long__builtin_cnttzdm(unsigned long long, unsigned long long) ¶

Perform a 64-bit count trailing zeros operation under mask, as ifimplemented by thecnttzdm instruction.

Built-in Function:unsigned long long__builtin_pdepd(unsigned long long, unsigned long long) ¶

Perform a 64-bit parallel bits deposit operation, as if implemented by thepdepd instruction.

Built-in Function:unsigned long long__builtin_pextd(unsigned long long, unsigned long long) ¶

Perform a 64-bit parallel bits extract operation, as if implemented by thepextd instruction.

Built-in Function:vector signed __int128vsx_xl_sext(signed long long, signed char *) ¶
