From f324a03ee23177e41509786bf09c9e7263989ff8 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Fri, 5 Jul 2024 09:40:26 +0100 Subject: [PATCH] linux-user/main: Suppress out-of-range comparison warning for clang MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit For arm32 host and arm64 guest we get .../main.c:851:32: error: result of comparison of constant 70368744177664 with expression of type 'unsigned long' is always false [-Werror,-Wtautological-constant-out-of-range-compare] if (TASK_UNMAPPED_BASE < reserved_va) { ~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~ We already disable -Wtype-limits here, for this exact comparison, but that is not enough for clang. Disable -Wtautological-compare as well, which is a superset. GCC ignores the unknown warning flag.
