Date: Wed, 02 Apr 2003 15:36:00 -0000 [thread overview]
Message-ID: <10304021500.AA20627@vlsi1.ultra.nyu.edu> (raw)
I still don't quite understand under what circumstances you would in
fact need to perform TImode computations at run time (that cannot be
optimized away at compile time). Do you have an example?
Somewhat contrived, but try:
procedure foo (x : integer) is
type r1(d: integer) is record
f1: string (1..d);
f2: integer;
end record;
rr1: r1 (x);
rr2: r1 (x * 2);
begin
if rr1'size > rr2'size then
raise program_error;
end if;
end foo;
This has *some* TImode computations, but not many.
