Yea, semantic patches are a bit confusing overall sometimes. > > But it looks like you got something which works? Actually, what I showed earlier does seem to have some weirdness with else-if. But I finally stumbled on something even better: - oidcmp(a, b) != 0 + !oideq(a, b) Because of the isomorphisms that coccinelle knows about, that catches everything we want. Obvious ones like: diff --git a/bisect.c b/bisect.c index 41c56a665e..7c1d8f1a6d 100644 --- a/bisect.c +++ b/bisect.c @@ -595,7 +595,7 @@ static struct commit_list *skip_away(struct commit_list *list, int count) for (i = 0; cur; cur = cur->next, i++) { if (i == index) { - if (oidcmp(&cur->item->object.oid, current_bad_oid)) + if (!oideq(&cur->item->object.oid, current_bad_oid)) return cur; if (previous) return previous; and compound conditionals like: diff --git a/blame.c b/blame.c index 10d72e36dd..538d0ab1aa 100644 --- a/blame.c +++ b/blame.c @@ -1834,7 +1834,7 @@ void setup_scoreboard(struct blame_scoreboard *sb, sb->revs->children.name = "children"; while (c->parents && - oidcmp(&c->object.oid, &sb->final->object.oid)) { + !oideq(&c->object.oid, &sb->final->object.oid)) { struct commit_list *l = xcalloc(1, sizeof(*l)); l->item = c; and even non-if contexts, like: diff --git a/sha1-file.c b/sha1-file.c index 631f6b9dc2..d85f4e93e1 100644 --- a/sha1-file.c +++ b/sha1-file.c @@ -825,7 +825,7 @@ int check_object_signature(const struct object_id *oid, void *map, if (map) { hash_object_file(map, size, type, &real_oid); - return oidcmp(oid, &real_oid) ? -1 : 0; + return !oideq(oid, &real_oid) ? -1 : 0; } So I think we have a winner. I'll polish that up into patches and send it out later tonight. -Peff
