Subject: nr2.0: Do not resolve modules this run if they are unloaded
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=fd6257bc2894124c328757ff08221580f6ea105b;p=thirdparty%2Fgcc.git

nr2.0: Do not resolve modules this run if they are unloaded

Instead, mark the visitor as dirty and wait for the next round of the fixed point to take care of
them. This avoids issues with module items being loaded while not being stripped yet.

gcc/rust/ChangeLog:

	* resolve/rust-toplevel-name-resolver-2.0.cc (TopLevel::visit): Return if module
	is unloaded.
