The C++ compiler in use here (1.0; we have 1.1 on order but it has yet to arrive) always declares ``this'' as a register argument. As Bjarne points out, if a function has little use for ``this'' (I have one that picks up an instance variable, goes through a complex loop that uses only local variables, and finally plugs the instance variable back) making ``this'' a register is a loss, particularly on Vax. In addition, it turns out that (again on Vax) the loop in question works out to be *much* faster if I can use a sixth register variable (the working set just happens to be six registers). + Do any of the newer compilers allow ``this'' to be other than register? + Does anyone have something clever to interpose between cfront and cc that gets rid of the register declaration? That gets rid of it for one entry function? Yes, I'm hacker enough to build my own, but why re-invent the wheel?
