I applied that patch - and can confirm that it fixes the LLVM issue (comment 4), but not the original issue (comment 0). Regarding comment 3, using -fdump-final-insns= without vs. with --param ggc-min-expand=0 --param ggc-min-heapsize=0 gives indeed a different result for comment 0's test case; however, that flag makes GCC extremely slow; the compile time goes up from 11s to 15min - which is also not the best for delta.pl reduction. The changes are in items such as 'net_stream.160_55->D.114439._vptr.' where D.114439 changes to D.114447 and the decl_uid in the ";; Function" lines changes.
