I worked on this as part of adding AArch64 support to my Linux kernel port (#5482).
It might be useful for other ports as well. I saw that AArch64 has been discussed (#4176). Other ports that run on AArch64 and don't have / don't want to use
setjmp
will be able to use this.I'm not done with adding the arch support in my port. It's cooked enough to test this, though - raising exception works fine, so I'm confident in the code correctness.
Once done with everything, I'll add other components such as
gchelper.s
support for AArch64 registers.Also dropped a small typo fix commit (that I've noticed while working on NLR).
