Currently -fopt-info-inline does nothing, as all of the dumping relating to inlining uses fprintf rather than dumpfile.h's dump_* interface.
This patch kit adds a %C format code to dumpfile.c for printing cgraph_node *, and uses it to port many of the IPA dump messages to the dump API. I focused on the dump messages that seemed most significant to end-users. With this kit, -fopt-info-inline prints messages at callsites such as e.g.: t.c:16:6: optimized: Inlining bar/1 into boo/2. t.c:15:11: optimized: Inlining foo/0 into boo/2. t.c:24:12: optimized: Inlining boo/2 into compute/3. and this can be checked for via the dg-optimized test directive (and appears in the -fsave-optimization-record result, etc).
