Division is inlined with -fcx-limited-range.

And yet, when trying to multiply numbers, gcc says that complex isn't a
supported type. From the links you provided, part of the
is case as well. Instead GCC lowers complex operations to
piecewise scalar operations, thus vectorization would have vectors
of the complex components. There are a number of bugs in bugzilla
for complex vectorization, like PR37021 or PR40770.

Hi,
I'm currently working on trying to implement a way to use the SIMD
instructions of the SSEx family when computing a vector of complex
numbers.
I have to say that I have never worked on compilation techniques before,
and that I only have little understanding of the vectorization problems.
I'v
