Ensure we hard stop via abort() for unhandled stub types rather than
continuing either silently (or noisly with a BFD_FAIL()).
Call abort() giving a hard stop rather than BFD_FAIL () for unhandled
stub types.

This relocation is a marker and does not result in a modification to
the binary. Changing the HOWTO bit field width to reflect this
property.
|
|
The HOWTO table entries for the TLSLE_MOVW_TPREL_* relocations are
wrong by inspection. The current implementation does not actually use
these field widths for these relocations but they should be corrected.

Unless pointer_equality_needed is set then set st_value to be zero

* elfnn-aarch64.c (elfNN_aarch64_finish_dynamic_symbol):
Set st_value to zero for undefined symbols if the reference
is weak or pointer_equality_needed is FALSE.

Commit ec93045b and cd21f5da introduced a large number of tic4x and
tic54x regressions, due to the new checks being wrong for targets
with octets_per_byte != 1. To fix that I introduced a new
bfd_get_section_limit_octets and performed the check on octets rather
than byte adresses, reducing the number of bfd_octets_per_byte calls.
bfd_octets_per_byte is rather expensive..
I then wondered why the same bfd_reloc_outofrange check added to
bfd_perform_relocation wasn't also added to bfd_install_relocation.
The two functions are virtually identical and ought to remain that
way. However, adding the same check to bfd_install_relocation
resulted in ld-elf "FAIL Link eh-group.o to eh-group" on many ELF
targets, including x64_64-linux. The reason being that eh-group.o
has NONE relocs at the end of a section, and most targets give NONE
relocs a non-zero size. So if we are to keep the new outofrange
check it appears that NONE relocs must have a zero size.

Copy relocs are used in a scheme to avoid dynamic text relocations in
non-PIC executables that refer to variables defined in shared
libraries. The idea is to have the linker define any such variable in
the executable, with a copy reloc copying the initial value, then have
both the executable and shared library refer to the executable copy.
If the shared library defines the variable as protected then we have
two copies of the variable being used.

If we are generating non-relocatable object and --emit-relocs specified,
aarch64 ld is actually generating wrong addend for rela entry when
relocate against local symbol.
for example, for simple testcase
foo.c
===
const char * const a = "foo";
const char *
foo ()
{
return a;
}
bar.c
===
const char * const b = "bar";
const char * bar ()
{
return b;
}
aarch64-none-linux-gnu-ld --emit-relocs -o x.o foo.o bar.o
aarch64-none-linux-gnu-readelf -r x.o
... R_AARCH64_ADR_PRE 0000000000400018 .rodata + 0

... R_AARCH64_ADD_ABS 0000000000400018 .rodata + 0
while it should be:
... R_AARCH64_ADR_PRE 0000000000400018 .rodata + 0
... R_AARCH64_ADD_ABS 0000000000400018 .rodata + 0

... R_AARCH64_ADD_ABS 0000000000400018 .rodata + 10
bfd generic code could actually handle this properly, but only when

Freeing the linker hash table is a royal pain. It can't be freed
before the _bfd_write_contents call in bfd_close, because some target
bfd_write_contents functions access the hash table. It can't be freed
after bfd_close either, since bfd_alloc memory holding side data
structures disappears (PR17047). Clearly the only place it can be freed
is actually in bfd_close. This patch doesn't do that, but kills off
the existing means of freeing the hash table via a bfd target xvec call.

The AArch64 TLSDESC to IE relaxation code uses a bit mask intended to
ensure that destination register in a relaxed ldr instruction is
always X0. The mask has an off by one error resulting in the most
significant bit of the destination register being retained in the
relaxed instruction. The issue generally appears when the compiler
emits TLS accesses code under high register pressure resulting in a
broken code sequence.

Add support for STT_GNU_IFUNC symbols to the AArch64 bfd backend. The tests
are ported from the ld-ifunc tests but are enabled for cross builds so can
be run easily without hardware or a simulator.
