I have been using note_stores to modify selected assignments. Now when I
try to move this code to gcc 4.4, I find that I get a warning because
my walker function takes a non-const rtx - and if I make it take a const
rtx,
there will be a warning somewhere inside because there is a code path
where a SET_SRC is modified.
data is in use to point to a libiberty hash table.
So, am I supposed to ignore the warning?
Roll my own copy of the original note_stores?
Resurrect the original note_stores in rtlanal.c (by whatever name)?
Use CONST_CAST_RTX where necessary.

Or pass in a struct pointer to the "data" parameter containing both your
hash table and the rtx to be modified. Pull out either member in the walker
function as necessary.
Me, I prefer being const-correct, but I understand not everyone shares my
enthusiasm for it. :-/
