Hello.

Following patch triggers hash calculation of items (functions and variables)
in situations where LTO mode is not utilized.

Patch survives regression tests and bootstraps on x86_64-linux-pc.

Ready for trunk?
Thanks,
Martin

Why does that make a difference?  Do we have direct ->hash users
that should have used get_hash ()?

Hmm, what is the difference to the LTO mode here. I would have expected that all the items
was analyzed in both paths?

Difference is that in case of the LTO mode, the hash value is read from streamed LTO file.
On the other hand, in classic compilation mode we have to force the calculation as a hash value
is computed lazily.

Please take a look at just sent suggested patch.

Thanks,
Martin

In this case we need to also handle cases where function/variable is born during WPA (i.e. produced
by earlier pass), so in_lto_p check looks wrong.
I will look at the updated patch.

Hi Honza.

Currently we just register {cgraph,varpool}_removal_hooks in WPA.
Probably place for enhancement?
