In C, -we used macros to : - - + declare a LOT of local integer and floating point variables - + load them with values - + check them at certain times - + to avoid floating point operations on CPUs w/o hardware support - -The macros are not equivalent to subprograms doing the same thing. -We are trying to insure that the register set is fully utilized and -checking that it survives context switches. If the routines are -subprograms, then calling conventions and scoping rules apply. Thus -the variables do not exist throughout the entire life of the task -as in the C test. - -It seems to point out that although the conditional compilation -and macro capabilities of C are often abused, they do provide -capabilities which are difficult if not impossible to mimic entirely -with subprograms. |
