Your patch will fix the problem, but, as I wrote in comment 10, I think it is
wrong. I guess you can change the semantics of tm_mangle() to return NULL for

The rs6000.c failure looks like rs6000_xcoff_section_type_flags() should deal
with decl == NULL.
But the other similar failure is in trans-mem.c:

How can I reproduce this additional error in trans-mem.c?
I believe that you need to use a target that does not define HAVE_COMDAT_GROUP.
Other targets do

I do not understand what you are asking. You can reproduce the failures or
you
cannot? My rs6000.c patch fixes some of the failures. The varasm.c patch

My patch did not fix the testsuite failures in trans-mem.c:tm_mangle() where
ipa_tm_create_version() and ipa_tm_create_version_alias() call tm_mangle() with

DECL_COMDAT field validly can be NULL on some targets. And most other uses
seem to be copying the value. I think that tm_mangle() needs to be prepared
