Hi; I'm wondering if anybody is using QEMU's iwmmxt/xscale emulation for toolchain testing. (My suspicion is the answer is "no".)

This emulation isn't enabled by default, so to use it you would have to explicitly select an iwmmxt capable CPU (with -cpu or the QEMU_CPU environment variable). The relevant CPU types are anything beginning "pxa" (pxa250, pxa255, pxa260, pxa261, pxa262, pxa270-a0, pxa270-a1, pxa270, pxa270-b0, pxa270-b1, pxa270-c0, pxa270-c5).

The context for this is that I'm considering deprecate-and-drop for this emulation. (We already dropped all the system emulation of boards that use these CPUs, so the only thing remaining is their support via QEMU's user-mode emulation.) If there's still somebody using this then I'm OK keeping it in QEMU a bit longer, but if as I suspect it's all entirely unused then we might as well start the process of dropping it.

(I'm aware that GCC is in the process of dropping its iwmmxt codegen support. I also didn't find anything particularly with a web search with examples of users using it.)
