[ Please CC me I am not subscribed to LKML and linux-kbuild ML ] Hi Linus,
I also tested with LLVM toolchain v11.0.1-rc2 together with passing LLVM=1 and LLVM_IAS=1 to my make line. I had one ERROR: error: too few operands for instruction in arch/x86/kvm/svm/sev.c The issue was reported in ClangBuiltLinux (CBL) issue #1216. A fix was offered in [2] and fixes the issue on the kernel-side. I had one WARNING: drivers/gpu/drm/i915/gem/i915_gem_execbuffer.o: warning: objtool: eb_relocate_parse_slow()+0x3d0: stack state mismatch: cfa1=7+120 cfa2=-1+0 drivers/gpu/drm/i915/gem/i915_gem_execbuffer.o: warning: objtool: eb_copy_relocations()+0x229: stack state mismatch: cfa1=7+120 cfa2=-1+0 Looks like a similar issue was reported as "drivers/gpu/drm/i915/gem/i915_gem_execbuffer: objtool warning on stack state mismatch" in [3]. I CCed Josh in the CBL issue #1192. Thanks.
