            Bug ID: 49415
           Summary: TestLinuxCore: two aarch64 reg test cases fail on
                    FreeBSD/aarch64
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: All Bugs

FAIL: LLDB (/home/mgorny/llvm-project/build.arm64/bin/clang-aarch64) ::
test_aarch64_regs (TestLinuxCore.LinuxCoreTestCase)
FAIL: LLDB (/home/mgorny/llvm-project/build.arm64/bin/clang-aarch64) ::
test_aarch64_sve_regs_fpsimd (TestLinuxCore.LinuxCoreTestCase)


The results look a bit suspicious -- like a rounding/printing problem.  I
wonder if it could be affected by some subtle stdlib difference.
