From eab17d763c6ca1bf74749e3a793fd044b5e6d457 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Wed, 27 Dec 2023 18:13:41 +0100 Subject: [PATCH] arch/Config.in: introduce BR2_ARCH_NEEDS_GCC_AT_LEAST_14 Since commit a0d2a5cfec0ade7cb577cbff25aac289e746e61b ("support/scripts/gen-bootlin-toolchains: generate BR2_ARCH_NEEDS_GCC_AT_LEAST_X guard"), the gen-bootlin-toolchains script will generate references to BR2_ARCH_NEEDS_GCC_AT_LEAST_X including potentially against the "next" version of gcc. Indeed, a toolchain using gcc 13.x should have a "depends on !BR2_ARCH_NEEDS_GCC_AT_LEAST_14" so that once some architectures that require gcc 14.x are added, such toolchains are not made visible. In order for this to work, we must have the BR2_ARCH_NEEDS_GCC_AT_LEAST_x symbol ready for the N+1 version of gcc compared to the latest one we support. As we're supporting up to gcc 13.x right now, let's introduce the symbol BR2_ARCH_NEEDS_GCC_AT_LEAST_14 so that gcc 13.x toolchains can be marked depends on !BR2_ARCH_NEEDS_GCC_AT_LEAST_14. The other alternative would be to make the gen-bootlin-toolchains a bit smarter, and not emit this depends on !BR2_ARCH_NEEDS_GCC_AT_LEAST_14 if BR2_ARCH_NEEDS_GCC_AT_LEAST_14 does not exist. But this would require re-running the script when BR2_ARCH_NEEDS_GCC_AT_LEAST_14 which we are unlikely to do. While today, when the script is invoked, the usual check-symbols complains and reminds us that BR2_ARCH_NEEDS_GCC_AT_LEAST_14 should be added, so we remember to do it right away.
