-X86 Built-in Functions
-----------------------
-
- These built-in functions are available for the i386 and x86-64 family
-of computers, depending on the command-line switches used.
-
- The following machine modes are available for use with MMX built-in
-functions (*note 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'.
-
- The following built-in functions are made available by `-mmmx'. All
-of them generate the machine instruction that is part of the name.
