------- Comment #3 from jakub at gcc dot gnu dot org 2010-01-25 12:59 ------- I mean that grep weak_import doc/* yields nothing at all (and google for weak_import doesn't show up any useful documentation either). It seems that Geoff Keating's implementation of the attribute (how could it be committed without documentation nor at least some words on what it is meant to do?) basically ignored it if weak attribute was also specified. Just removing those lookup_attribute (, "weak") tests would cure this. That really depends on what __attribute__((weak, weak_import)) is supposed to mean (if anything). Or what means combination of #pragma weak and weak_import attribute for the same decl name. Also, what matters is if undefined weak_import symbols are supposed to generate weak directives or not.
