------- Comment #14 from rguenth at gcc dot gnu dot org 2010-02-14 21:29 ------- That doesn't make sense. The symbol is not TREE_READONLY.
Was that dump from inside get_symbol_constant_value? As the extract only happens from CCP2 I suppose that ipa-reference might be setting TREE_READONLY on the decl becaue it's static and not written to? So, can you try with -fno-ipa-reference? (-fdump-ipa-reference should show "read-only var OBJC_CLASS_REFERENCES_0" if that is the problem) Can it be that the next runtime causes functions to be emitted in the back of cgraph? Or maybe the objc frontend fails to set TREE_ADDRESSABLE on those vars? Or it forgets to pass them to the varpool? Can you attach the full ipa-reference dump and the full 004.gimple dump? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43061
