1 6.59.15 MIPS Loongson Built-in Functions
1 ----------------------------------------
1
1 GCC provides intrinsics to access the SIMD instructions provided by the
1 ST Microelectronics Loongson-2E and -2F processors. These intrinsics,
1 available after inclusion of the 'loongson.h' header file, operate on
1 the following 64-bit vector types:
1
1 * 'uint8x8_t', a vector of eight unsigned 8-bit integers;
1 * 'uint16x4_t', a vector of four unsigned 16-bit integers;
1 * 'uint32x2_t', a vector of two unsigned 32-bit integers;
1 * 'int8x8_t', a vector of eight signed 8-bit integers;
1 * 'int16x4_t', a vector of four signed 16-bit integers;
1 * 'int32x2_t', a vector of two signed 32-bit integers.
1
1 The intrinsics provided are listed below; each is named after the
1 machine instruction to which it corresponds, with suffixes added as
1 appropriate to distinguish intrinsics that expand to the same machine
1 instruction yet have different argument types. Refer to the
1 architecture documentation for a description of the functionality of
1 each instruction.
