The compiler is assuming that function calls only clobber memory and since there were no register dependencies created, it was pulling up all the calls to the built-ins before the arithmetic operations. When I changed the variable Val from an auto int variable to a pointer to an int in the global space and changed all reference to it appropriately, everything fell back into shape. When you say convert the built-in into an asm do you mean that I should replace the built-in itself with inline assembly in the source that I am compiling or is that something that I can do in the expand stage of the built-in? I will explore the latter with other ports while I await your reply. Thanks and regards Ayonam
