  --use-blx                   Enable use of BLX instructions
  --vfp11-denorm-fix          Specify how to fix VFP11 denorm erratum
  --fix-stm32l4xx-629360      Specify how to fix STM32L4XX 629360 erratum
  --no-enum-size-warning      Don't warn about objects with incompatible
                                enum sizes
  --no-wchar-size-warning     Don't warn about objects with incompatible
                                wchar_t sizes
  --pic-veneer                Always generate PIC interworking veneers
  --long-plt                  Generate long .plt entries
                              to handle large .plt/.got displacements
  --cmse-implib               Make import library to be a secure gateway import
                                library as per ARMv8-M Security Extensions
  --in-implib                 Import library whose symbols address must
                                remain stable
  --stub-group-size=N         Maximum size of a group of input sections that
                                can be handled by one stub section.  A negative
                                value locates all stubs after their branches
                                (with a group size of -N), while a positive
                                value allows two groups of input sections, one
                                before, and one after each stub section.
                                Values of +/-1 indicate the linker should
                                choose suitable defaults.

  --no-merge-exidx-entries    Disable merging exidx entries
  --[no-]fix-arm1176          Disable/enable ARM1176 BLX immediate erratum fix
