This bug, as are the other ones I filed are not strictly limited to arm-none-linux-gnu. I am simply using a using arm-none-linux-gnu toolchain to reproduce and report the issue. These likely effect all apcs-gnu toolchains, and looking at config.gcc, there are more configurations that follow that than gnueabi configurations. So basically you're saying that NEON is only supported in arm-none-linux-gnueabi configurations because it's only been tested there. As for the expecting it to work, ICE are always bugs so until support for these configurations are removed these are valid bugs. Whether bugs get closed, as fixed or wontfix, doesn't make them less of a bug.
