6.64.39 x86 Built-in Functions

These built-in functions are available for the x86-32 and x86-64 family of computers, depending on the command-line switches used.

If you specify command-line switches such as -msse, the compiler could use the extended instruction sets even if the built-ins are not used explicitly in the program. For this reason, applications that perform run-time CPU detection must compile separate files for each supported architecture, using the appropriate flags. In particular, the file containing the CPU detection code should be compiled without these options.

The following machine modes are available for use with MMX built-in functions (see Using Vector Instructions through Built-in Functions): V2SI for a vector of two 32-bit integers, V4HI for a vector of four 16-bit integers, and V8QI for a vector of eight 8-bit integers. Some of the built-in functions operate on MMX registers as a whole 64-bit entity, these use V1DI as their mode.

If 3DNow! extensions are enabled, V2SF is used as a mode for a vector of two 32-bit floating-point values.

If SSE extensions are enabled, V4SF is used for a vector of four 32-bit floating-point values. Some instructions use a vector of four 32-bit integers, these use V4SI. Finally, some instructions operate on an entire vector register, interpreting it as a 128-bit integer, these use mode TI.

The x86-32 and x86-64 family of processors use additional built-in functions for efficient use of TF (__float128) 128-bit floating point and TC 128-bit complex floating-point values.

The following floating-point built-in functions are always available:

Built-in Function: __float128 __builtin_fabsq (__float128 x))

Computes the absolute value of x.

Built-in Function: __float128 __builtin_copysignq (__float128 x, __float128 y)

Copies the sign of y into x and returns the new value of x.

Built-in Function: __float128 __builtin_infq (void)

Similar to __builtin_inf, except the return type is __float128.

Built-in Function: __float128 __builtin_huge_valq (void)

Similar to __builtin_huge_val, except the return type is __float128.

Built-in Function: __float128 __builtin_nanq (void)

Similar to __builtin_nan, except the return type is __float128.

Built-in Function: __float128 __builtin_nansq (void)

Similar to __builtin_nans, except the return type is __float128.

The following built-in function is always available.

Built-in Function: void __builtin_ia32_pause (void)

Generates the pause machine instruction with a compiler memory barrier.

The following built-in functions are always available and can be used to check the target platform type.

Built-in Function: void __builtin_cpu_init (void)

This function runs the CPU detection code to check the type of CPU and the features supported. This built-in function needs to be invoked along with the built-in functions to check CPU type and features, __builtin_cpu_is and __builtin_cpu_supports, only when used in a function that is executed before any constructors are called. The CPU detection code is automatically executed in a very high priority constructor.

For example, this function has to be used in ifunc resolvers that check for CPU type using the built-in functions __builtin_cpu_is and __builtin_cpu_supports, or in constructors on targets that don’t support constructor priority. 


static void (*resolve_memcpy (void)) (void)
{
  // ifunc resolvers fire before constructors, explicitly call the init
  // function.
  __builtin_cpu_init ();
  if (__builtin_cpu_supports ("ssse3"))
    return ssse3_memcpy; // super fast memcpy with ssse3 instructions.
  else
    return default_memcpy;
}

void *memcpy (void *, const void *, size_t)
     __attribute__ ((ifunc ("resolve_memcpy")));
