Subject: [kvm-unit-tests PATCH v3 0/7] x86: Fix duplicate symbols w/ clang
Date: Thu, 9 Sep 2021 11:32:00 -0700 [thread overview]
Message-ID: <20210909183207.2228273-1-seanjc@google.com> (raw)
Add a "noinline" macro to mirror the kernel's wrapping of the attribute
and to save typing, and use it to fix a variety of duplicate symbol errors
that pop up with some versions of clang due to clang aggressively inlining
functions that define globally visible labels in inline asm blobs.
Bill Wendling (5):
lib: define the "noinline" macro
x86: realmode: mark exec_in_big_real_mode as noinline
x86: svm: mark test_run as noinline
x86: umip: mark do_ring3 as noinline
x86: vmx: mark some test_* functions as noinline
Sean Christopherson (2):
lib: Drop x86/processor.h's barrier() in favor of compiler.h version
lib: Move __unused attribute macro to compiler.h
