gcc45-pr42508.patch
Fix, so far not bootstrapped/regtested. The cgraphunit.c hunk is only somewhat
related, is not necessary to fix this, I've just noticed that the function was
still modifying GIMPLE_CALL decl unnecessarily (and confusingly), when
e->callee is an inline clone of some cgraph node with same_body aliases and
GIMPLE_CALL calls the same_body alias.
