Billy Laws c978fdd12f WOW64: Implement basic code invalidation handling 2023-09-22 10:12:40 -07:00
Billy Laws 19713bd20a WOW64: Implement exception handling with context restoration 
When an exception occurs, pretend that we were just at the point of JIT entry
so the stack can be unwound to the wow64 SEH handler, which then handles
dispatching the exception to the x86 guest with the restored context.

Billy Laws 22b1fea96d WOW64: Handle unaligned atomic accesses 
This is done in EnsureConsistentState rather than as a VEH to avoid needing to
go through all of wine's exception handling logic for such a hot path.

Billy Laws 2add8a7751 Windows: Introduce a barebones FEXCore-based WOW64 BT module 
This allows for running x86 applications under wine without having to run all
of wine under FEX. The JIT is invoked when running application code and then
left when handling NT syscalls or unix calls to e.g. the Vulkan driver.
