That has stopped being true for at least a decade or more. C was
designed to map well to the PDP-11's instruction set; modern CPU's are
completely different beasts with out-of-order execution, cache
hierarchy, multi-core, multi-thread per core, expanded instruction sets,
and microcode. Why do you think, for example, that in the kernel
functions and intrinsics are used for certain CPU-specific instructions?
Because nothing in C itself corresponds to them.  The closeness of C to
the CPU is only an illusion.
