Hi Paul,
The patch actually consists of two parts:
1) The resolve.c part prevents the conversion to a PPC call via the
_vptr (for functions and subroutines).
This is obviously OK

2) The class.c parts prevents adding the non-overridable TBP to the vtable.

This patch fixes the bug PR50663, as I reported at:

basic block that implicit set is recorded for.

This won't work - DECL_UIDs are not stable -g vs. -g0 - only their
_order_ is stable - thus you won't get comparison fails with code generated
dependent on DECL_UID order, but you will if you depend on the DECL_UID
value (which you do by using it as a hash).
And we will still generate

By this patch branch-cost optimization is moved from tree AST to cfgexpand
from gimple to RTL. By this we are able to do better optimization on

This is a patch that cleans up the code for loading CONST or SYMBOL_REF into a
register.
This code is also needed to be able to load symbols into PSImode registers.
Up to now, this is not needed because there are no 24-bit symbols yet, but it
is needed for 24-bit address spaces.

Otherwise the patch looks ok, but given the Ada issue let's wait until

I can certainly move this to expand_call_stmt() if you prefer. Do you have
an objection to the RTL walk? This isn't my code, but I'm open to
suggestions on an alternative to implement.
It just catched my eye... moving it to expand_call_stmt would be nice
indeed, but I was suggesting to add

I also wonder if instead of a new pass control-dependent DCE can be
taught of this?
It could. I'm not sure it really buys us anything except maybe being
able to reuse the pdom control-dependency analysis.
It actually more naturally belongs in
