> it is possible to make C code run quickly but only by spending thousands of person-years building a sufficiently smart compiler Just because some of the C++ code I write heavily relies on ISA-specific SIMD intrinsics doesn’t replace the language with some other one, it’s remains to be C++. Compared to solving the general problem by making a sufficiently smart automatically vectorizing C compiler, learning SIMD intrinsics is way more manageable. BTW, a few years ago I wrote an article about SSE 1-4 and AVX 1-2 ISA extensions, as exposed to C and C++ languages: http://const.me/articles/simd/simd.pdf |
