Thank You Very Much In Advance.

Quote: I overloaded operator+ in a class, and I want to invoke this operator in inline assemble like this: _asm call operator+ but it cannot be complied OK. Why do you need to call the operator from assembly language? Quote: compiler says there are some illegalI opcodes, and I'm absolutely sure that all the other codes are OK. Humm. Better double check if you violate the instruction-set. Check the syntax as well...

Thank You Very Much In Advance. Well, you have to disassemble the code, at get the name, function pointer, and figure out the calling convention, and just call it. It might not have a CABI...

Thank You Very Much In Advance. operator + (a,b) is a function like any other so write a small sample code that uses the operator+ and get your compiler to produce some assembler output. Look at the actual name of the function called (turn off optimisation to show the function being called maybe), which will probably be something long and weird and use that name instead of operator+, Unfortunately some compilers change function names in assembler IIRC so you should check your compiler manual for details. Also bear in mind that if you have an optimising compiler you will invariably lose by using assembler but I guess its fun to see how the compiler does stuff so go for it... regards Andy Little regards Andy Little Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         C++Talk.NET Forum Index -> C++ language (comp.lang.c++) All times are GMT Page 1 of 1   Jump to: Select a forum C/C++----------------C LanguageC Language (Moderated)C++ Language (Moderated)C++ language (comp.lang.c++)C++ language, library and standards Non-English C/C++ Newsgroups----------------C++ (German)C++ (French)  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
