56228a853b - moved all exports from class Font to vmthunks.cpp and gave them direct native entrypoints. 
- changed PARAM_STRING to use the passed string by reference instead of by value. The 3 instances where passing by value was needed now use PARAM_STRING_VAL.

0746784965 - implemented unwind data on Unix - does it work? no idea, there's no easy way to tell when the debugger doesn't support the interface.. 2019-04-16 17:40:48 +02:00

f2ac0f4c53 - 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.

178c1a41a6 - moved VM thunks from p_sectors.cpp to a separate file and started adding direct native implementations. 
For a few larger functions I took them out of sector_t and made them global functions to avoid creating more unnecessary stubs.

c01981d08a - define the built-in functions defined in codegen.cpp through the regular interface instead uf just hacking them into the symbol table with incompletely set up data.

20ec6ddce4 - removed AStateProvider from native code. 
The only place still referencing it was CallStateChain, so this has been made a static function now instead of a class method.

309cc57504 - removed all direct access to AWeapon's members to prepare moving this class fully to the script side. 
Disregarding UI-side and setup-related calls there's unfortunately still 6 places in the native game code which require direct access.

ce5792242c - moved the 'Finalize' methods back into a single function in the parser code. 
It has been like this initially but was changed when ZDoom gained an overly complicated polymorphic class descriptor object that required a lot of support code. All these complications have long been removed but these methods remained. Since they prevent a class from being moved to the script side entirely they had to be removed.

This was the last major blocker to make Weapon a purely scripted class, the only remaining native method is Serialize which is of no concern for the coming work.

ac754b5e96 - some cleanup on the weapon slot interface.

Christoph Oelckers
0515af2bd3 - removed the bot related properties from AWeapon. 
This stuff is now kept locally in the bot code so that it doesn't infest the rest of the engine.
And please don't read the new botsupp.txt file as some new means to configure bots! This was merely done to get this data out of the way.
The bots are still broken beyond repair and virtually unusable, even if proper data is provided for all weapons.

5f5410e35f - fixed: Since out types cannot be marked as such in a function prototype (as it'd cause parameter mismatches in the resolving pass) it is necessary to check the argflags as well when determining the register type. 2019-04-15 21:56:26 +02:00

edfe8b36c6 - cleaned up the PointerSubstitution code 
Since the only thing it gets used for is swapping out PlayerPawns it can safely skip all global variables that never point to a live player, which allowed to remove quite a bit of code here that stood in the way of scriptifying more content
 2019-04-15 16:06:22 +02:00
Christoph Oelckers
5e63252fdc - moved the type infomation entirely out of VMValue. 
For the varargs functions that used the Type field to validate their parameters, now a hidden additional argument is passed which contains a byte array with the type info for the current call's arguments. Since this is static per call location it can be better prepared once when the code is being compiled instead of being put in a runtime created array for each invocation. Everything else uses the per-function instance of the same data.

The only thing that still needed the type field with a VMValue is the defaults array, so this uses a different struct type now to store its data.
