27ecae265d - improve the stack trace when the jit is active 2018-12-18 11:44:51 +01:00

ad8f484836 - fixed: The JIT compiler crashed on missing ArgFlags. 
For ad-hoc Dehacked state functions no ArgFlags are created, in this case they can just be assumed to not be relevant here, because none of these function produces reference arguments.

d7da2d838f - handle JIT errors in a more user-friendly fashion than aborting. 
* use I_Error instead of I_FatalError to abort. I_FatalError is only for things that are not recoverable and should not be handled outside of error cleanup and rethrowing.
* only catch CRecoverableError in JitCompile. Everything else should fall through to the outermost catch block.
* Do not I_FatalError out after handling the exception locally. Just print an error and return null, indicating failure.

42b9a41421 - removed the longjmp based exception catch/rethrow mechanism and instead force-terminate in case a user exception is thrown while the VM is executing JITed code on a non-Windows system 
On Windows none of this is needed, because we can generate a proper unwind frame for the JITed functions, but even on Linux, it would require manual additions to each single piece of native code that ever gets called from inside a JIT compiled function.
This is an utterly prohibitive proposition because it makes direct native calls a virtual impossibility
So, in order to get the thrown error properly presented both I_Error and ThrowAbortException will now forward to I_FatalError if it is called from inside a JIT context.

0394dc56b7 - generate a memset for the allocated stack memory because that's what the VM does 
(this really shouldn't be done by the VM either - the compiler backend should clear its registers if it wants them to be zero!)
