From: Nick Desaulniers Date: Mon, 21 Jun 2021 23:18:21 +0000 (-0700) Subject: compiler_attributes.h: cleanups for GCC 4.9+ X-Git-Tag: v5.15~850^2~2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ae4d682dfd3350d9836dafeed1fc5aa1e27c4963;p=platform%2Fkernel%2Flinux-starfive.git compiler_attributes.h: cleanups for GCC 4.9+ Since commit 6ec4476ac825 ("Raise gcc version requirement to 4.9") we no longer support building the kernel with GCC 4.8; drop the preprocess checks for __GNUC_MINOR__ version. It's implied that if __GNUC_MAJOR__ is 4, then the only supported version of __GNUC_MINOR__ left is 9.
