Between 20171115 (r254778) and 20171116 (r254837), one testcase regressed on
Solaris 11/SPARC (both 32 and 64-bit):
+FAIL: g++.dg/tree-prof/partition1.C compilation, -fprofile-use -D_PROFILE_USE
(internal compiler error)
+UNRESOLVED: g++.dg/tree-prof/partition1.C execution, -fprofile-use
-D_PROFILE_USE
during RTL pass: dwarf2
/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/tree-prof/partition1.C: In
function 'int main()':
/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/tree-prof/partition1.C:53:1:
internal compiler error: in create_pseudo_cfg, at dwarf2cfi.c:2840

Given the timeframe, it seems likely that one of Jan's patches is the culprit.
