Ensure that injection of a stub section does not break a link where
there is an xpectation that flow of control can pass from one input
section to another simply by linking the input sections in series.
The solution here is to allow stub sections to be inserted after any
input section (existing behaviour), but inject an additional branch at
the start of each stub section such that control flow falling into the
stub section will branch over the stub section.

Change the behaviour of section_group[] such that .stub_sec points to
the stub section attached to the indexed section rather than the stub
section attached to the link_section pointed to be the index section.
This provides a mechanism to get to the stub section following any
input section. While still allowing the section grouping mechanism to
find the section group stub section associated with an input section
by first following the link_sec pointer.

This patch recognizes that we only need to perform one scan for the
835769 errata and that this scan can take place before we insert
branch stubs. The erratum scan code is relocated and adjusted to
create stub entries directly rather than populating an intermediate
representation. Since stub entries are created immediately we can
drop the adhoc stub size adjustment code and allow the generic stub
sizing code to deal with 835769 stub entries.
This patch restructures the code but does not change the workaround
used to deal with erratum 83679, the exact placement of workaround
stubs in the final image may change slightly after this patch due to
stubs being created in a different order.
|
|
Adjust the 835769 workaround code to use
_bfd_aarch64_add_stub_entry_in_group rather than inspect the
underlying section_group structure directly.

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.

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;
}

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.

This function seems to be a left over from some previous

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.
