aarch64-darwin NCG appears to be broken
A recent CI build has many errors of the form:
/tmp/ghc75623_0/ghc_5.s:448:10: error: error: invalid octal escape sequence (out of range) in '.string' directive .string "\742\644\633" ^ | 448 | .string "\742\644\633" | ^
I actually can't find any jobs which are not broken in some way. It seems that the NCG is quite badly broken still..
