b428136866 - unwind data is now working on macOS 2018-12-01 12:46:35 +01:00
Christoph Oelckers
a7e472b4b3 - 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.

c41603c171 - 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.. 2018-12-01 01:14:15 +01:00

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.

a501a22b28 - 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.

b267252a09 - 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. 2018-11-24 09:34:53 +01:00

3ba6290419 - add support in the jit compiler to do direct native calls using the x64 calling convention 2018-11-23 04:47:18 +01:00
Christoph Oelckers
a9ec819557 - 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.

a981737855 - 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.

629d329f22 - 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.

97573a0452 - 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.

1a2e5b12d0 - RUNTIME_FUNCTION only exists in 64-bit Windows 2018-10-14 22:54:30 +02:00
Christoph Oelckers
dd719f0f14 - extended the register limit for 'param'. 
The instruction one free instruction byte so it's now using that to extend its argument's register range to 65535.
For param this is needed because it passes strings by reference and creating an implicit temporary copy for string constants does not work here.
