--- Comment #10 from Jeffrey A. Law <law at gcc dot gnu.org> --- Encouraging: ==497119== Conditional jump or move depends on uninitialised value(s) ==497119== at 0x8C858B: improve_allocation() (ira-color.cc:3388) ==497119== by 0x8CE92E: color_allocnos (ira-color.cc:3616) ==497119== by 0x8CE92E: color_pass(ira_loop_tree_node*) (ira-color.cc:3725) ==497119== by 0x8B5DA5: ira_traverse_loop_tree(bool, ira_loop_tree_node*, void (*)(ira_loop_tree_node*), void (*)(ira_loop_tree_node*)) (ira-build.cc:1784) ==497119== by 0x8CAD27: do_coloring (ira-color.cc:3861) We're doing a cost based test, so goofing this up won't cause incorrect code, but could change meaningfully. Now time to dive into whether or not it's been fixed or just gone latent.
