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.
