To whom it may concern, In the interests of improving the type-safety of our future var_args implementation in an OS project I have founded, we are possibly interested in implementing some slight variations of the cdecl and thiscall conventions for the x86 architecture (thiscall2 and cdecl2.) Can anybody please help us locate where exactly in gcc-trunk's sourcecode the implementations of these conventions would be located? Our modifications to thiscall and cdecl would include the following (in a general sort of order)-  - PUSH the number of arguments used in a "..." before the list of arguments begins  - PUSH the total size of the arguments used in a "..." call before the list of arguments begins  - Before each argument, push an 8-bit 'arguments' flag denoting whether or not the type being pushed is (or resolves to):   0. is a signed type (1 if yes, 0 if no).   1. is an integer   2. is a  char   3. is a  short   4. is a  long   5. is a  double   6. is a long-long   7. is an complex/compound type (ie. struct, class, etc.) This way, our standard libraries and debugging tools could (at-least semi-)accurately deduce types and function call usage patterns for var_args code being debugged on our OS. Thanks in advance, - Robert
