  26 # The goal of this test is to verify that support for the R_AARCH64_NONE
  27 # relocation is implemented and it can be used to inform a linker that
  28 # a section should be preserved during garbage collecting.
  29 # File aarch64_reloc_none.s describes two similar sections, .foo and .bar,
  30 # but .foo is referenced from .text using R_AARCH64_NONE against symbol foo.
  31 # When flag --gc-sections is used, .foo and its symbol foo have to be
  32 # preserved, whereas .bar and its symbol bar have to be discarded.
