- Subject: Fix write_symbol testsuite ICE
Hi,
this patch fixes the ICE while streaming out alias nodes. It is all somewhat ugly,
since some aliases have varpool/cgraph nodes while others doesn't depending on
if they are or are not used in code...
Bootstrapped/regtested x86_64-linux, comitted as obvious.
