From 22a8fa09e81337f45c2ed94e229f06e9aaa32c0e Mon Sep 17 00:00:00 2001 From: Akira Hatanaka Date: Wed, 5 Jun 2024 11:02:31 -0700 Subject: [PATCH] Check whether EvaluatedStmt::Value is valid in VarDecl::hasInit VarDecl::isNull() doesn't tell whether the VarDecl has an initializer as methods like ensureEvaluatedStmt can create an EvaluatedStmt even when there isn't an initializer. Revert e1c3e16d24b5cc097ff08e9283f53319acd3f245 as the change isn't needed anymore with this change.
