Hear, hear, hear!

I hereby give the following notice:

The data types `FunctionEntry`, `StackFrame` and `FPUContext` in the

user-defined functions handling code (`source/vm/fnpovfpu.h`) SHALL be

subject to change, now and forever more.

The commend currently preceding these data structures:

// WARNING: Do not change this structure without notice!!!

// Platform specific code may depend on the exact layout and size! [trf]

will be removed without replacement.

To the best of my knowledge there is not, and never has been, any

platform-specific code that does, or ever did, rely on these structures.

If I'm mistaken there, please let me know.

If I remember well, there was a JITC but only for the Macintosh version v3.6

JITC for the PPC (G4, G5,…)

Maybe that was the reason for it?

Something someone should implement again for x86? ;-)



Look at perforce/povray/3.6-release/macintosh/backend/MacFastfunctions.cpp
