Hi, This patch disables strict aliasing in the Algol 68 frontend by setting flag_strict_aliasing to 0 in a68_post_options().
The frontend builds successfully and make check-algol68 passes with this change. Thanks, Kanishka Solanki
From f3174dd8524b57f10aa53d8dc4c13f334d0d4944 Mon Sep 17 00:00:00 2001 From: Kanishka Solanki <[email protected]> Date: Sat, 20 Jun 2026 02:25:49 +0530 Subject: [PATCH] disable strict aliasing in Algol 68 frontend The Algol 68 frontend does not want strict aliasing rules. Disable strict aliasing in a68_post_options() by setting flag_strict_aliasing to 0. Strict aliasing had been enabled temporarily while investigating test failures with it disabled. The frontend now builds correctly and the Algol 68 testsuite passes with strict aliasing disabled. gcc/algol68/ChangeLog * a68-lang.cc (a68_post_options): Disable strict aliasing.
