Subject: [PATCH 0/2] kbuild: userprogs: two fixes for LLVM=1
Date: Thu, 13 Feb 2025 15:55:16 +0100 [thread overview]
Message-ID: <20250213-kbuild-userprog-fixes-v1-0-f255fb477d98@linutronix.de> (raw)
Fix two issues when cross-building userprogs with clang.
Reproducer, using nolibc to avoid libc requirements for cross building:
$ tail -2 init/Makefile
userprogs-always-y += test-llvm
test-llvm-userccflags += -nostdlib -nolibc -static -isystem usr/ -include $(srctree)/tools/include/nolibc/nolibc.h
$ cat init/test-llvm.c
int main(void)
{
return 0;
}
$ make ARCH=arm64 LLVM=1 allnoconfig headers_install init/
Validate that init/test-llvm builds and has the correct binary format.
