a8ce626708 Pointer addition opcodes must leave NULL pointers as they are. 2018-08-16 21:45:04 +02:00

591783087d Changed binary int ops to use a temporary register, fixed some opcodes. 
For some reason, binary ops might reuse one of the input registers as the output register.
This is a problem for very obvious reasons.

1ed415014e - fixed: 'self' may never be null for native VM functions so it must always abort if null gets passed. 2017-06-05 08:43:12 +02:00

b50123ec6b - avoid function call in VM code. 
- return after calling ThrowAbortException because this avoids storing some register variables on the stack.

6599e2c425 - moved the VM types into their own file and only include it where really needed. 2017-04-13 01:12:04 +02:00
Christoph Oelckers
fc9e304189 - separated class descriptors from VM types. 
Combining these two groups of data has been the cause of many hard to detect errors because it allowed liberal casting between types that are used for completely different things.

7a6e70e777 - reenabled the part of OP_THROW that throws a VMAbortException. This part is still needed for a runtime variable access check. 2017-04-11 00:11:36 +02:00

d5edd3db36 Commented out remains of VM exception handling opcodes 
This fixes build with GCC/Clang

040c70714c - commented out the exception handling opcodes in the VM. 
They are currently not used and not planned to be used - and they are rather costly by increasing stack size per call quite significantly.

ef77cbd295 - stop using the ATAGs for checking pointer types in asserts. 
This is an incredibly costly way to do a debug check as it infests the entire VM design from top to bottom. These tags are basically useless for anything else but validating object pointers being passed to native functions (i.e. mismatches between definition and declaration) and that simply does not justify a feature that costs execution time in non-debug builds and added memory overhead everywhere.
Note that this commit does not remove the tags, it only discontinues their use.

e780cd8297 - seems the wrong version of this got committed... 2017-04-01 12:04:31 +02:00

41f2f61b94 - minor VM optimization: Precalculate a function's frame size when compiling it instead of doing it each time it gets called. 
This made up ca. 10% of the 'call' instruction's execution time.

31ea33bfc4 - rewrote the condition nodes from SBARINFO in ZScript. This compiles but hasn't been tested yet. 2017-03-23 00:25:26 +01:00
Christoph Oelckers
9bd75bcac5 - some conceptual work on statusbar stuff. This looks like a viable approach to build something that can replace SBARINFO. 2017-03-22 19:56:21 +01:00
Christoph Oelckers
4417afd548 - changed VMValue to handle strings by reference. 
This makes VMValue a real POD type with no hacky overloads and eliminates a lot of destructor code in all places that call a VM function. Due to the way this had to be handled, none of these destructors could be skipped because any value could have been a string.
This required some minor changes in functions that passed a temporary FString into the VM to ensure that the temporary object lives long enough to be handled. The code generator had already been changed to deal with this in a previous commit.
This is easily offset by the code savings and reduced maintenance needs elsewhere.

9bffe4ee50 - scriptified the main statusbar interface and the Strife status bar. 
Note that the Strife status bar does not draw the health bars yet. I tried to replace the hacky custom texture with a single fill operation but had to find out that all the coordinate mangling for the status bar is being done deep in the video code. This needs to be fixed before this can be made to work.

Currently this is not usable in mods because they cannot initialize custom status bars yet.

7aa6a6b0b3 Restored explicit assignment operators for VMValue 
Unfortunately strings require special handling and so all operators must be available
This partly solves https://mantis.zdoom.org/view.php?id=453 (and https://mantis.zdoom.org/view.php?id=459 too)

403c5693a9 - cleaned out a large part of unused methods from VMValue. 
- keep string registers which are being used as function parameters allocated until after the function call returns. This is for allowing to pass strings by reference which would avoid some costly constructor/destructor loops in the call instruction.
