May I recommend that you mark this PR as a draft until it is ready ? Anyways, thanks for seeing this through I've a few remarks that aren't noted in your todo.

Lots of stack alignment for Linux are missing. Specifically in

* [ ]  `x64GenContext::GeneratePubFunc`

* [ ]  `x64GenContext::CallEndContext`

* [ ]  `x64GenContext::DoReturn`

* [ ]  `x64GenContext::PrepareReturn`

* [ ]  `x64GenContext::GenerateCallHooks`

* [ ]  `retInfo.pAssignOperator`

* [ ]  `retInfo.pDtor`

* [ ]  `x64GenContext::CallSetupHookLoop` (You also need to handle parameter 7, 8, 9 & 10)

Alignment for these were added with the latest commit:

  • CallEndContext
  • DoReturn
  • PrepareReturn
  • GenerateCallHooks
  • pAssignOperator
  • pDtor

TODO still because they're a bit more than just copy & pasting.

  • TODO GeneratePubFunc
  • TODO CallSetupHookLoop

This was going to be glue & bandaids in the short-term but I burned out. Kenzzer's work on nuking sourcehook/related in mms & sm to allow something to completely replace the systems (khook) is a better way forward.
