[Bug 1749597] Re: [aarch64] gas: Error: non-constant expression in ".if" statement

[Stephen Warren]

For my own understanding, I'm curious:

a) Whether Ubuntu toolchains are usually updated for bugs like this

b) Roughly how often toolchain updates are usually released. I suppose
you're busy with Spectre stuff right now though?
