From 5b8f5a50a93c5fd44fa1ecb6f431fee1df267571 Mon Sep 17 00:00:00 2001 From: Martin Liska Date: Wed, 15 Dec 2021 17:27:56 +0100 Subject: [PATCH] pragma: respect pragma in lambda functions In g:01ad8c54fdca we started supporting target pragma changes that are primarily caused by optimization option. The same can happen in the opposite way and we need to check for changes both in optimization_current_node and target_option_current_node.
