[Pkg-julia-devel] Bug#861484: julia: FTBFS on arm64

[Edmund Grimley Evans]

This problem is caused by:

How I discovered this, would be a long story.

The effect of the LLVM bug is to OR the register field of a
"movz xD, #IMM, lsl #48" with bits 43-47 of an address. With some
kernels those bits are always zero, so no harm is done. If you can
build julia, which is just a matter of using an appropriate system,
then you might as well ship it. It will be useful for some people
even if the LLVM bug does not get fixed.

There is probably no need to rebuild julia when the LLVM bug has been fixed,
but you should probably check that with someone who properly understands
how julia works.
