Paths in attributes (fn walk_attribute) are also not visited, so if any issue affects fn-like macros, then it affects attributes as well.

The problem with these methods is that there's no proper node id to pass, but if passing DUMMY_NODE_ID doesn't cause ICEs or anything like that, then sure, we should visit those paths.

@petrochenkov petrochenkov added S-waiting-on-author Status: This is awaiting some action (such as code changes or more information) from the author. and removed S-waiting-on-review Status: Awaiting review from the assignee but also interested parties. labels Mar 27, 2019

It fails here:

match self.tcx.hir().get(id) {

with:

error: internal compiler error: src/librustc/hir/map/mod.rs:628: couldn't find node id 1 in the AST map

I'm not sure why this is id 1, rather than NodeId::MAX (i.e. DUMMY_NODE_ID), which would then get caught by this check:

Minimal reproduction:

// -Z save-analysis

#![feature(global_asm)]

fn main() {}

NodeId(1) looks like an ID created with placeholder_from_mark.

Ok, looks like we'll have to leave attributes for some other time.
r=me with the changes to fn walk_mac alone.
