The bugs are: (a) The second parameter gets pushed first and then the registers of bank 0. This should be other way. (b) The registers of bank 2 are pushed first and then regbank 0 is, but, while poping, the registers of bank 2 are poped first and then regbank 0 is poped. This should be other way. The attached source file (includes ASM file as a comment at the end of this source file) describes these bugs. - Suresh B Joshi ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=100599&aid=662594&group_id=599 |
