7 years agold: Allow section groups to be resolved as part of a relocatable link
Andrew Burgess [Wed, 22 Mar 2017 17:27:49 +0000 (17:27 +0000)]
ld: Allow section groups to be resolved as part of a relocatable link

This commit adds a new linker feature: the ability to resolve section
groups as part of a relocatable link.

Currently section groups are automatically resolved when performing a
final link, and are carried through when performing a relocatable link.
By carried through this means that one copy of each section group (from
all the copies that might be found in all the input files) is placed
into the output file.  Sections that are part of a section group will
not match input section specifiers within a linker script and are
forcibly kept as separate sections.

There is a slight resemblance between section groups and common
section.  Like section groups, common sections are carried through when
performing a relocatable link, and resolved (allocated actual space)
only at final link time.

However, with common sections there is an ability to force the linker to
allocate space for the common sections when performing a relocatable
link, there's currently no such ability for section groups.

This commit adds such a mechanism.  This new facility can be accessed in
two ways, first there's a command line switch --force-group-allocation,
second, there's a new linker script command FORCE_GROUP_ALLOCATION.  If
one of these is used when performing a relocatable link then the linker
will resolve the section groups as though it were performing a final
link, the section group will be deleted, and the members of the group
will be placed like normal input sections.  If there are multiple copies
of the group (from multiple input files) then only one copy of the group
members will be placed, the duplicate copies will be discarded.

Unlike common sections that have the --no-define-common command line
flag, and INHIBIT_COMMON_ALLOCATION linker script command there is no
way to prevent group resolution during a final link, this is because the
ELF gABI specifically prohibits the presence of SHT_GROUP sections in a
fully linked executable.  However, the code as written should make
adding such a feature trivial, setting the new resolve_section_groups
flag to false during a final link should work as you'd expect.

Correct a commit e5713223cbc1 ("MIPS/BFD: For n64 hold the number of

relocation handling in the generic ELF BFD linker code such that, except

reads input sections.

The handling of dynamic relocations remains unchanged and they continue

C++ify breakpoint class hierarchy (destructors only)

Breakpoints are currently in a limbo state between C and C++.  There is
a pseudo class hierarchy implemented using struct fields.  Taking
watchpoint as an example:

  struct watchpoint
  {
    /* The base class.  */
    struct breakpoint base;

    ...
  }

and it is instantianted with "new watchpoint ()".  When destroyed, a
destructor is first invoked through the breakpoint_ops, and then the
memory is freed by calling delete through a pointer to breakpoint.
Address sanitizer complains about this, for example, because we new and
delete the same memory using different types.

This patch takes the logical step of making breakpoint subclasses extend
the breakpoint class for real, and converts their destructors to actual
C++ destructors.

7 years agoCreate struct type for longjmp breakpoint
Simon Marchi [Fri, 2 Jun 2017 21:16:20 +0000 (23:16 +0200)]
Create struct type for longjmp breakpoint

The longjmp kind of breakpoint has a destructor, but doesn't have an
associated structure.  The next patch converts breakpoint destructors from
breakpoint_ops::dtor to actual destructors, but to do that it is needed
for longjmp_breakpoint to have a structure that will contain such
destructor.  This patch adds it.

According to initialize_breakpoint_ops, a longjmp breakpoint derives
from "momentary breakpoints", so eventually a momentary_breakpoint
struct/class should probably be created.  It's not necessary for the
destructor though, so a structure type for this abstract kind of
breakpoint can be added when we fully convert breakpoint ops into
methods of the breakpoint type hierarchy.

It is now necessary to instantiate different kinds of breakpoint objects
in set_raw_breakpoint_without_location based on bptype (sometimes a
breakpoint, sometimes a longjmp_breakpoint), so it now uses
new_breakpoint_from_type to do that.  I also changed set_raw_breakpoint
to use it, even though I don't think that it can ever receive a bptype
that actually requires it.  However, I think it's good if all breakpoint

7 years agoUse the ELF class to determine the word size for FreeBSD core notes.
John Baldwin [Thu, 1 Jun 2017 16:40:46 +0000 (09:40 -0700)]
Use the ELF class to determine the word size for FreeBSD core notes.

FreeBSD ELF cores contain data structures with that have two different
layouts: one for ILP32 platforms and a second for LP64 platforms.
Previously, the code used 'bits_per_word' from 'arch_info', but this
field is not a reliable indicator of the format for FreeBSD MIPS cores
in particular.

I had originally posted this patch back in November because process
cores for FreeBSD MIPS contained an e_flags value of 0 in the header
which resulted in a bfd_arch which always had 'bits_per_word' set to
32.  This permitted reading o32 cores, but not n64 cores.  The feedback
I received then was to try to change n64 cores to use a different
default bfd_arch that had a 64-bit 'bits_per_word' when e_flags was zero.
I submitted a patch to that effect but it was never approved.  Instead,
I changed FreeBSD's kernel and gcore commands to preserve the e_flags
field from an executable when generating process cores.  With a proper
e_flags field in process cores, n64 cores now use a 64-bit bfd_arch and
now work fine.  However, the change to include e_flags in the process
cores had the unintended side effect of breaking handling of o32
process cores.  Specifically, FreeBSD MIPS builds o32 with a default
MIPS architecture of 'mips3', thus FreeBSD process cores with a non-zero
e_flags match the 'mips3' bfd_arch which has 64 'bits_per_word'.

From this, it seems that 'bits_per_word' for FreeBSD MIPS is not likely
to ever be completely correct.  However, FreeBSD core dumps do
reliably set the ELF class to ELFCLASS32 for cores using ILP32 and
ELFCLASS64 for cores using LP64.  As such, I think my original patch of
using the ELF class instead of 'bits_per_word' is probably the simplest
and most reliable approach for detecting the note structure layout.

PPC64_OPT_LOCALENTRY

ELFv2 functions with localentry:0 are those with a single entry point,
ie. global entry == local entry, and that have no requirement on r2 or
r12, and guarantee r2 is unchanged on return.  Such an external
function can be called via the PLT without saving r2 or restoring it
on return, avoiding a common load-hit-store for small functions.   The
optimization is attractive.  The TOC pointer load-hit-store is a major
reason why calls to small functions that need no register saves, or
with shrink-wrap, no register saves on a fast path, are slow on
powerpc64le.

To be safe, this optimization needs ld.so support to check that the
run-time matches link-time function implementation.  If a function
in a shared library with st_other localentry non-zero is called
without saving and restoring r2, r2 will be trashed on return, leading
to segfaults.  For that reason the optimization does not happen for
weak functions since a weak definition is a fairly solid hint that the
function will likely be overridden.  I'm also not enabling the
optimization by default unless glibc-2.26 is detected, which should

[ARC] Allow CPU to be enforced via disassemble_info options

Currently print_insn_arc relies on BFD mach and ELF private headers to
distinguish between various ARC architectures.  Sometimes those values are not
correct or available, mainly in the case of debugging targets without and ELF
file available.  Changing a BFD mach is not a problem for the debugger, because
this is a generic BFD field, and GDB, for example, already sets it according to
information provided in XML target description or specified via GDB 'set arch'
command.  However, things are more complicated for ELF private headers, since
it requires existing of an actual ELF file.  To workaround this problem this
patch allows CPU model to be specified via disassemble info options.  If CPU is
specified in options, then it will take a higher precedence than whatever might
be specified in ELF file.

This is mostly needed for ARC EM and ARC HS, because they have the same
"architecture" (mach) ARCv2 and differ in their private ELF headers.  Other ARC
architectures can be distinguished between each other purely via "mach" field.

Proposed disassemble option format is "cpu=<CPU>", where CPU can be any valid
ARC CPU name as supported by GAS.  Note that this creates a seeming redundancy
with objdump -m/--architecture option, however -mEM and -mHS still result in
"ARCv2" architecture internally, while -Mcpu={HS,EM} would have an actual

[ARC] Implement compatible function for ARC BFD architectures

The general rule for bfd_arch_info_type->compatible (A, B) is that if A and B
are compatible, then this function should return architecture that is more
"feature-rich", that is, can run both A and B.  ARCv2, EM and HS all has same
mach number, so bfd_default_compatible assumes they are the same, and returns
an A.  That causes issues with GDB, because GDB assumes that if machines are
compatible, then "compatible ()" always returns same machine regardless of
argument order.  As a result GDB gets confused because, for example,
compatible(ARCv2, EM) returns ARCv2, but compatible(EM, ARCv2) returns EM,
hence GDB is not sure if they are compatible and prints a warning.
