gcc48-pr55193.patch
Untested fix. For changes to DEBUG_INSNs, generally simplify_replace_fn_rtx
is the best thing, it takes care of simplifying everything that is needed, both
for the cases where something changes from non-VOIDmode into VOIDmode (then
simplification is required; e.g. as on this testcase (zero_extend:DI (reg:SI
eax) 0) where eax is replaced by (const_int 0)), and a nice thing to have
otherwise.
