It is with SOM.
I would say we have missing .import directives at least for first:
_ZTVN12_GLOBAL__N_18pass_dceE:
.word 0
.word 0
.word P%_ZN12_GLOBAL__N_18pass_dceD1Ev
.word P%_ZN12_GLOBAL__N_18pass_dceD0Ev
.word P%_ZN12_GLOBAL__N_18pass_dce5cloneEv
.word P%_ZN12_GLOBAL__N_18pass_dce4gateEP8function
.word P%_ZN12_GLOBAL__N_18pass_dce7executeEP8function
There is no local definition of
_ZN12_GLOBAL__N_18pass_dce4gateEP8function and
no .import directive for it.
r220868 was ok and r220883 bad.

My guess is that the problem was introduced in r220875.

Certainly possible. We ought to be able to see the problem at the assembly
level with a cross compiler, which will help greatly with debugging :-)
I wonder if the ICF framework unified the gate function with something else.
That ought to show up in the .icf dump.

Darn, I just deleted preprocessed source.
This bug may be related to PR 65150 which is fixed. Need to recheck.

Damn, while I was away, the one thing that came to mind was to ask you for the
preprocessed source so that the issue could be analyzed with a cross compiler.
If indeed this is fixed by 65150, then I'll count us as lucky.
Obviously if it isn't fixed by the patch for 65150, please attach the
preprocessed source for further investigation.
