From 9a22717b9b074d75baf7dd6041487730e53b4dbb Mon Sep 17 00:00:00 2001 From: Nick Desaulniers Date: Wed, 30 Mar 2022 11:34:06 -0700 Subject: kbuild: uapi: use -fsyntax-only rather than -S The UAPI header tests are checking that the generated headers do not have syntax errors. There's no need to run the rest of the compilation pipeline after semantic analysis has run. Replace -S -o /dev/null with -fsyntax-only.
