Describe the feature you'd like
We should have LAVA support injecting bugs into ARM.
Additional context
Some comments to note to myself of work needing to be done for this to work
LAVA:
1- Review LavaTool, especially once chaff bugs are in; it looks like there is assembly specific to x86-64. We will need to do something similar for AARCH
2- Currently, the hypercall (on LAVA's side) only works with x86-64; we should, at a minimum, see how to update this to support AARCH Registers. This issue is already fixed in PR #87, as seen in the commit "Prepare for multi-arch LAVA".
3- This will come with a full deprecation of Bash, but we should have a way to adjust compiler flags based on architecture. This would make changing architecture easy. See PR #87, as seen in the commit "Prepare for multi-arch LAVA".
PANDA:
1- file_taint needs to support ARM. There is a PR underway
2- dwarf2 needs to also support ARM, I'm working on the PR for this, but will only attempt to get it merged after some testing.
