f2fe079ddb - fixed the reginfo checks for the Draw... functions. 
They need to be offset by the same amount as the arguments so that the values are properly matched.

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.

cb9c1f021c - generate register type info for the parameter lists of all functions. 
Currently used for loading parameters into registers.
For checking parameters of native functions some more work is needed to get the info to the function. Currently it doesn't receive the function descriptor.

6727301330 - moved all code related to function calls into the helper class so that all future work on the calling convention is in one place only. 2019-04-15 15:52:12 +02:00

a900390683 - moved all handling for the simple calls into EmitterArray to have it in one place only. 
The main case of FxVmFunctionCall is not done yet, though.

054640ce41 - removed OP_TAIL. 
The amount of support code for this minor optimization was quite large and this stood in the way of streamlining the VM's calling convention, so it was preferable to remove it before moving on.

ab689c0984 - fixed TArray's Append methods. 
I mistakenly assumed that Grow would incease the array's reserved space.

e9a5f094c9 - changed OP_PARAM handling so that all registers remain allocated until the call instruction and reordered instruction emission so that the param instructions all directly precede the call instruction. 2019-04-15 15:48:37 +02:00

03001991f1 - fixed IJMP code generation for the JIT compiler. 
With a proper count value available this can be done properly. The only relevant targets are the jumps immediately succeeding the IJMP instructions, nothing else.

f557c77602 - do not use instructions from too recent instruction set extensions. 
andn is part of BMI1 which was introduced in 2012, which is far too recent to be used unchecked.

9456c877d4 - deconstruct A_Jump with multiple labels into A_Jump(chance, RandomPick(label1, label2, label3,...)) to remove this ugly special case from the VM calling convention. 
This also adds the number of available choices to OP_IJMP.

075a666c75 - stop using lambda functions for CreateCall because MSVC lambas use a different calling convention and "converts" them to the right one by generating a thunk function 2019-04-15 14:37:44 +02:00

66a970059b - add warning text when falling back to the VM 2019-04-15 14:37:41 +02:00
Christoph Oelckers
7d2c4a05e2 - removed the unused 'no arguments' cases from the BuiltinRandom functions and split off BuiltinRandom2 into its own function. 
This removes the last non-vararg cases where a native VM function checks 'numparam'. As of this commit all function calls will pass the complete list of arguments.

44eee13aa7 - build full argument lists for action function calls. 
This uses one static global array to avoid frequent reallocations.

a371a8456a - implemented VMCallWithDefaults and used it for all calls with variable arguments. 
This isn't used for the 3 action function calls because it requires an array allocation which would be a bit too costly for something as frequently called as action functions.
They will need a different approach.

28461de6ec - marked all places where an incomplete parameter list may be passed to the VM by a native call by redirecting VMCall to an intermediate VMCallWithDefaults. This function must later fill in the missing arguments from the default. 2019-04-15 14:37:30 +02:00
Christoph Oelckers
7fe33d336c Avoid using argument count for any kind of decision making in native VM functions. 
This allows retaining the functionality, even if for the JIT compiler's benefit all default arguments are pushed onto the stack instead of reading them from the defaults array.
