Next: MIPS DSP Built-in Functions, Previous: FR-V Built-in Functions, Up: Target Builtins
These built-in functions are available for the i386 and x86-64 family of computers, depending on the command-line switches used.
Note that, 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 which perform runtime 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 Vector Extensions): 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 DI 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.
In 64-bit mode, the x86-64 family of processors uses 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 available in 64-bit mode. All of them implement the function that is part of the name.
__float128 __builtin_fabsq (__float128)
__float128 __builtin_copysignq (__float128, __float128)
The following floating point built-in functions are made available in the 64-bit mode.
__float128 __builtin_infq (void)__builtin_inf, except the return type is __float128.
The following built-in functions are made available by -mmmx. All of them generate the machine instruction that is part of the name.
