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.
