Subject: [PATCH 01/14] KVM: selftests: Define literal to asm constraint in aarch64 as unsigned long
Date: Tue, 13 Dec 2022 00:16:40 +0000	[thread overview]
Message-ID: <20221213001653.3852042-2-seanjc@google.com> (raw)
In-Reply-To: <20221213001653.3852042-1-seanjc@google.com>

Define a literal '0' asm input constraint to aarch64/page_fault_test's
guest_cas() as an unsigned long to make clang happy.

  tools/testing/selftests/kvm/aarch64/page_fault_test.c:120:16: error:
    value size does not match register size specified by the constraint
    and modifier [-Werror,-Wasm-operand-widths]
                       :: "r" (0), "r" (TEST_DATA), "r" (guest_test_memory));
                               ^
  tools/testing/selftests/kvm/aarch64/page_fault_test.c:119:15: note:
    use constraint modifier "w"
                       "casal %0, %1, [%2]\n"
                              ^~
                              %w0
