From df16aaac26e92e97ab7234d3f93c953466adc4b5 Mon Sep 17 00:00:00 2001 From: Nick Desaulniers Date: Sat, 7 Oct 2017 13:23:23 -0700 Subject: kbuild: clang: remove crufty HOSTCFLAGS When compiling with `make CC=clang HOSTCC=clang`, I was seeing warnings that clang did not recognize -fno-delete-null-pointer-checks for HOSTCC targets. These were added in commit 61163efae020 ("kbuild: LLVMLinux: Add Kbuild support for building kernel with Clang"). Clang does not support -fno-delete-null-pointer-checks, so adding it to HOSTCFLAGS if HOSTCC is clang does not make sense. It's not clear why the other warnings were disabled, and just for HOSTCFLAGS, but I can remove them, add -Werror to HOSTCFLAGS and compile with clang just fine.
