And lastly, gcc has recently gained intrinsic support for some SIMD operations whereby the coder requests a vector of specified dimension and content, and then performs operations on that vector. Depending on compiler flags, these operations translate into either SIMD instructions or regular opcodes.

This code builds fine and works expectedly using gcc (it's inbuild SSE / MMX extensions and vector data types. this code is doing a SIMD vector addition using 4 single floats. I want to understand in detail what does each keyword/function call on this typedef line means and does:

GCC provides intrinsics to access the SIMD instructions provided by the MSA MIPS SIMD Architecture. The interface is made available by including <msa.h> and using -mmsa -mhard-float -mfp64 -mnan=2008.For each __builtin_msa_*, there is a shortened name of the intrinsic, __msa_*.. MSA implements 128-bit wide vector registers, operating on 8-, 16-, 32- and 64-bit integer, 16- and 32-bit …

The AVX instructions support both 128-bit and 256-bit SIMD. The 128-bit versions can be useful to improve old code without needing to widen the vectorization, and avoid the penalty of going from SSE to AVX, they are also faster on some early AMD implementations of AVX. ... Compiler and assembler support. GCC starting with version 4.6 ...

With the new #pragma GCC ivdep, the user can assert that there are no loop-carried dependencies which would prevent concurrent execution of consecutive iterations using SIMD (single instruction multiple data) instructions. Support for Cilk Plus has been added and can be enabled with the -fcilkplus option. Cilk Plus is an extension to the C and ...
