            Bug ID: 45483
           Summary: Add -z cet-report=[none|warning|error]
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: ELF
          Assignee: unassignedbugs at nondot.org
          Reporter: hjl.tools at gmail.com

GNU BFD linker supports -z cet-report=[none|warning|error]:

     'cet-report=none'
     'cet-report=warning'
     'cet-report=error'
          Specify how to report the missing
          GNU_PROPERTY_X86_FEATURE_1_IBT and
          GNU_PROPERTY_X86_FEATURE_1_SHSTK properties in input
          .note.gnu.property section.  'cet-report=none', which is the
          default, will make the linker not report missing properties in
          input files.  'cet-report=warning' will make the linker issue
          a warning for missing properties in input files.
          'cet-report=error' will make the linker issue an error for
          missing properties in input files.  Note that 'ibt' will turn
          off the missing GNU_PROPERTY_X86_FEATURE_1_IBT property report
          and 'shstk' will turn off the missing
          GNU_PROPERTY_X86_FEATURE_1_SHSTK property report.  Supported
          for Linux/i386 and Linux/x86_64.
