Comment 2 for bug 1576233

The arm64 is missing at least arm64 assembler code for cdata in ciborium's included qml.v1 copy. I've been trying to craft qml.v1/cdata/cdata14_arm64.s, but I haven't been able to come up with anything that would build. If you know someone who would be familiar with arm64 assembler it could help. The Go arm64 support is marked as experimental in general (https://golang.org/doc/asm#arm64).

There's also a C version of cdata that was apparently used before Go 1.4, I'm not sure if it would be usable as a workaround.

Note that I'm not familiar with Ciborium aside from rebuilding it to be able to ship newer Qt. Ciborium doesn't currently have a maintainer.
