------- Comment #22 from mueller at gcc dot gnu dot org 2008-08-25 07:59 -------
there is currently no good way to detect if a block is dead during the VRP
pass, as the VRP information is used for *determining* wether or not a block is
dead.
Is there a general warning-queuing implementation that I could make use of or
is there some other warning that does that already? Iirc the "is used/ might be
used uninitialized" type of warnings do not use something like that.
