I did not mention it there but it is true there are some longterm unfixed
bugs in DWZ so that it gives up on optimization of many builds:
error: Allocatable section after non-allocatable ones
https://sourceware.org/bugzilla/show_bug.cgi?id=24251#c10
That isn't a longterm unfixed bug. It is is a comment by you from a
couple of days ago that you could still reproduce an already fixed
bug. So we reopened the bug and asked you for a reproducer. Which you
didn't provide. When we then tried to replicate the issue ourselves we
found that dwz correctly seems to detect an issue with the golang
toolchain.
error: Couldn't find DIE referenced by DW_AT_abstract_origin
(maybe DWZ error or maybe compiler error: Unknown DWARF DW_OP_255)
We cannot fix bugs if you don't report them. Please file bugs for the
above issue (including how to reproduce them) and we'll take a look.
Cheers,
Mark
