From 9a950154668729a472d17b8e307d92e7c60f45f7 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Thu, 23 Apr 2020 23:23:54 +0900 Subject: kbuild: use CONFIG_CC_VERSION_TEXT to construct LINUX_COMPILER macro scripts/mkcompile_h runs $(CC) just for getting the version string. Reuse CONFIG_CC_VERSION_TEXT for optimization. For GCC, this slightly changes the version string. I do not think it is a big deal as we do not have the defined format for LINUX_COMPILER. In fact, the recent commit 4dcc9a88448a ("kbuild: mkcompile_h: Include $LD version in /proc/version") added the linker version.
