An earlier version of my patches had casting methods within the
gimple_statement_base class, which were rejected; the above proposals
would instead put them within gimple_stmt_iterator.
I would like all gsi routines to be consistent, not a mix of functions
and methods.
so something like
stmt = gsi_as_call (gsi);
stmt = gsi_dyn_call (gsi);
or we need to change gsi_stmt() and friends into methods and access
them
as gsi->stmt ().. which is possibly better, but that much more
intrusive again (another 2000+ locations).
If we switched to methods everywhere for gsi, I'd prefer something like
gsi->as_a_call ()
gsi->is_a_call ()
gsi->dyn_cast_call ()
I think its more readable... and it removes a dependency on the
implementation.. so if we ever decide to change the name of 'gcall'
down
the road to using a namespace, and make it gimple::call or whatever, we
wont have to change every single gsi-> location which has a templated
use of the type.
I'm also think this sort of thing could probably wait until next stage
1..
my 2 cents...
