The psABI (AAELF) says this about mapping symbols:
4.6.5.1 Section-relative mapping symbols
Mapping symbols defined in a section define a sequence of
half-open address intervals that cover the address range of the
section. Each interval starts at the address defined by the
mapping symbol, and continues up to, but not including, the
address defined by the next (in address order) mapping symbol or
the end of the section. A section must have a mapping symbol
defined at the beginning of the section; however, if the section
contains only data then the mapping symbol may be omitted.
That makes it pretty clear that, in the absence of a mapping symbol,
the entire section can be treated as data.

* aarch64.cc (AArch64_relobj::scan_errata): Drop missing symbol warning.
* arm.cc (Arm_relobj::scan_section_for_cortex_a8_erratum): Drop missing

* aarch64.cc (AArch64_relobj::do_count_local_symbols): Make legal
of mapping symbols.
The crash reason is that the insn to be moved to stub may be a
relocation spot, so instead of placing the origin insn (that is insn
before-relocation) to the stub, I have to place the relocated one.
Note the relocation involved is non-pc-relative, so it is safe to move
the relocated insn.

statically/non-statically linked

When linking the following tlsdesc access sequence into an executable with -pie,
adrp x0, :tlsdesc:tls_gd
ldr x1, [x0, #:tlsdesc_lo12:tls_gd]
add x0, x0, :tlsdesc_lo12:tls_gd
.tlsdesccall tls_gd
blr x1
mrs x1, tpidr_el0
add x0, x1, x0
ldr w0, [x0]
current gold-aarch64 backend does tls-desc-gd-to-ie relaxation, into
adrp x0, 1000 <__FRAME_END__+0x720>
ldr x1, [x0,#4064] ;; <=== the target register should be x0
nop
nop
mrs x1, tpidr_el0
add x0, x1, x0
ldr w0, [x0]
This code is wrong. The fix changes ldr target register into x0.

-- Add support for ifunc.
-- Enable safe icf
-- Add support for TLSLD relocations
R_AARCH64_TLSLD_ADR_PAGE21,
R_AARCH64_TLSLD_ADD_LO12_NC,

-- Add support for TLSLD->TLSLE relaxation.
-- Add support for R_AARCH64_LD_PREL_LO19, R_AARCH64_ADR_PREL_LO21.
-- Fix 2 encoding bugs in AArch64_relocate_functions::update_movnz.
-- Correct TLS relocation properties in gold/aarch64-reloc.def.
-- Update testsuite/icf_safe_so_test.cc, testsuite/icf_safe_test.sh.
