According to "ELF for the ARM(r) 64-bit Architecture (AArch64)", this relocation can be used "to prevent removal of sections that might otherwise appear to be unused." gold/ * aarch64-reloc.def (NONE): New relocation. * aarch64.cc (Target_aarch64::Scan::local): Handle R_AARCH64_NONE. (Target_aarch64::Scan::global): Likewise. * testsuite/Makefile.am (aarch64_reloc_none): New test. * testsuite/Makefile.in: Regenerate. * testsuite/aarch64_reloc_none.s: New test source file. * testsuite/aarch64_reloc_none.sh: New test script.

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