    • combine: Don't do make_more_copies for dest PC (PR87720) · b8ac9576 
      Jumps are written in RTL as moves to PC.  But the latter has no mode,
so we shouldn't try to use it.  Since the optimization this routine
does does not really help for jumps at all, let's just skip it.


	PR rtl-optimization/87720
	* combine.c (make_more_copies): Skip if the dest is pc_rtx.

    • gOlogy: do not change code in isolate-paths for warnings only · f8719680 
      The isolate-paths pass is activated by various -f flags, but also by
-Wnull-dereference.  Most of its codegen changes are conditioned on at
least one of the -f flags, but those that detect, warn about and
isolate paths that return the address of local variables are enabled
even if the pass is activated only by -Wnull-dereference.

-W flags should not cause codegen changes, so this patch makes the
codegen changes conditional on the presence of any of the -f flags
that activate the pass.  Should we have a separate option to activate
only this kind of transformation?
