commit 51d591d8f15b50c6966b3871b572775a236d433a Author: Thomas Schwinge <tschwi...@baylibre.com> Date: Wed Jul 17 18:02:50 2024 +0200 Add 'g++.target/nvptx/alias-g++.dg_init_dtor2-1.C' ... as one minimized example for the issue that with nvptx '-malias' enabled (as implemented in commit f8b15e177155960017ac0c5daef8780d1127f91c "[nvptx] Use .alias directive for mptx >= 6.3"), there are hundreds of instances of link-time 'unresolved symbol [alias]' across the C++ test suite, which are regressions compared to a test run with (default) '-mno-alias'.
