I have just started experimenting with POASM subroutines called from Pelle C. Since I have a Win7 64-bit computer, in-lining is not allowed, but I found it surprisingly easy to get started with a separate *.asm source file. I now have a question for the experts:
1) Pelle's explanation of the 'fastcall' convention does not cover use of registers other than rcx,rdx,r8,r9 & rax. I suspect that he follows Microsoft's Visual C++ rules, which state that the above 5 registers plus r10 & r11 are 'volatile' while all others should be preserved, i.e. PUSHed and POPped. Is this correct?
