target.

 - Remove the [is_remote target] check.
 - Remove soname setting when building the lib, it's done by default now
   anyway.
 - In the compilation of the executable, pass the shared lib using the
   shlib option, so that RPATH is set.
 - Download the program to the target using gdb_remote_download, and
   record the remote path.  Remove loading of the program using
   gdb_load_shlibs, which was not really appropriate anyway.
 - Run the remote path through readlink (see comment in the code).
 - Start gdbserver with the remote path.

Also, don't set executable and objfile variables, as they are unused.

Tested with native, native-gdbserver, native-extended-gdbserver, and a
remote gdbserver.

The compiled code's .debug_line is wrong (for the simplistic approach of GDB
to put a breakpoint on the first address belonging to that source line) and so
GDB misses the breakpoint at the last line:

which then finds the specific arc_opcode that we're assembling.  We

gas/arc: Modify structure used to hold opcodes

The arc assembler builds a hash table to hold references to arc_opcode
entries in the arc_opcodes table.  This hash assumes that each mnemonic
will always appear in a contiguous blocks within the arc_opcodes table;
all ADD instruction will be together, all AND instructions will likewise
be together and so on.

The problem with this is that as different variations of arc are added,
then it is often more convenient to split instructions apart, so all the
base ADD instructions are together, but, variants of ADD specific to one
variation of arc are grouped with other instructions specific to that
arc variant.  The current data structures don't support splitting the
instructions in this way.

This commit is a first step towards addressing this limitation.  In this
commit the hash table that currently holds arc_opcode pointers directly,
instead holds a pointer to a new, intermediate, data structure.  This
new data structure holds the pointer to the arc_opcode.  In this way, we
can, in the future support having the intermediate structure hold
multiple pointers to different arc_opcode groups.

There should be no visible functional change after this commit.

we can see breakpoint on 0x85f4 are inserted *twice*, but only removed
once.  That is fine to remote target, because Z/z packets are
idempotent, but there is a leftover in record_full_breakpoints
in record-full target.  The flow can be described as below,

                                record_full_breakpoints   remote target
  -----------------------------------------------------------------------
  forward execution, continue,    in_target_beneath 1     breakpoint inserted
  insert breakpoints on 0x85f4    in_target_beneath 1
  twice

  program stops,
  remove breakpoint on 0x85f4     in_target_beneath 1     breakpoint removed

  reverse execution, continue,    in_target_beneath 1     none is requested
  insert breakpoints on 0x85f4,   in_target_beneath 0

  program stops,
  remote breakpoint on 0x85f4,    in_target_beneath 0     request to remove,
                                                          but GDBserver
  doesn't know

now, the question is why breakoint on 0x85f4 is inserted twice?  One
is the normal breakpoint, and the other is the single step breakpoint.
GDB inserts single step breakpoint to do single step.  When program
stops at 0x85f4, both of them are set on 0x85f4, and GDB deletes
single step breakpoint, so in update_global_location_list, this
breakpoint location is no longer found, GDB call
force_breakpoint_reinsertion to mark it condition_updated, and insert
it again.

The reason force_breakpoint_reinsertion is called to update the
conditions in the target side, because the conditions may be
changed.  My original fix is to not call force_breakpoint_reinsertion
if OLD_LOC->cond is NULL, but it is not correct if another location
on the same address has condition, GDB doesn't produce condition for
target side, but GDB should do.

Then, I change my mind back to make record-full handling breakpoint
idempotent, to align with remote target.  Before insert a new entry
into record_full_breakpoints, look for existing one on the same
address first.  I also add an assert on
"bp->in_target_beneath == in_target_beneath", to be safer.

ld/arc: Make little endian default choice for linker scripts

When building with --enable-targets=all the target string is not set to
something that matches the pattern arc*-*, and so the script used to
decide if we should build big or little endian linker script currently
exits with an error.

This commit makes little endian linker script be the default, which will
be used when building for all targets, this matches the behaviour from

gas/arc: Allow greater range of characters into flag names

An upcoming commit will add a new arc instruction flag that uses
characters that have never appeared in an arc instruction flag before.
Currently the assembler is very conservative about which characters can
or cannot appear in an instruction flag.

This commit relaxes these constraints a little.  After this commit all
alpha-numeric characters are now allowed into instruction flags.  This
complete set is not required for the upcoming change, however, having
this slightly larger set does not impact the assemblers ability to

instruction table.

Eliminate -var-create error for optzd ptr to struct

This patch eliminates an error thrown when accessing the value of a
pointer to a structure where the pointer has been optimized out and
'set print object' is 'on'.  The error shows up as the rather ugly
value of the pointer variable in Eclipse.

If 'set print object' is 'on', GDB tries to determine the actual
(derived) type of the object rather than the declared type, which
requires dereferencing the pointer, which in this cases throws an
error because the pointer has been optimized out.

The fix is to simply ignore the 'print object on' setting for
pointers or references to structures when they have been optimized
out.  This means we just get the declared type instead of the actual
type, because in this case that's the best that we can do.

To implement the fix, value_optimized_out was modified so that it
no longer throws an error when it fails to fetch the specified
value.  Instead, it just checks value->optimized_out.  If we can't
definitively say that the value is optimized out, then we assume
it is not.

Make ftrace tests work with remote targets

When we build a shared library for testing, it is built differently
whether it is meant for the local system or a remote one.  When it is
for the local system, the library is built with no SONAME.  So when the
executable is built, roughly in this way:

  $ gcc testfile.c /path/to/library.so

the executable will contain an absolute reference to the library.  For
example:

  $ readelf -a testsuite/gdb.python/py-shared | grep NEEDED
   0x0000000000000001 (NEEDED)             Shared library: [/home/emaisin/build/binutils-gdb/gdb/testsuite/gdb.python/py-shared-sl.sl]

When testing is done remotely, the absolute path obviously doesn't work.
Therefore, we build the library with an SONAME:

  $ readelf -a testsuite/gdb.python/py-shared-sl.sl | grep SONAME
   0x000000000000000e (SONAME)             Library soname: [py-shared-sl.sl]

which ends up in the executable's NEEDED field:

  $ readelf -a testsuite/gdb.python/py-shared | grep NEEDED
   0x0000000000000001 (NEEDED)             Shared library: [py-shared-sl.sl]

The executable and the library are then uploaded side-by-side on the
remote system.  To allow the dynamic linker to find the shared library,
we have to add the special RPATH value $ORIGIN, which tells it to search
in the executable's directory:

  $ readelf -a testsuite/gdb.python/py-shared | grep ORIGIN
   0x000000000000000f (RPATH)              Library rpath: [$ORIGIN]

The problem with the IPA library is that it doesn't have an SONAME,
making it very difficult to do testing on a remote board.  When a
test executable is linked with it, it contains an absolute reference to
the library path.  Therefore, unless the paths on the target are the
same as on the build system, it won't work.

To make it possible for tests using the IPA library to run test on
remote boards, I suggest adding an SONAME to libinproctrace.so.  I don't
think it should be a big problem for users.  All the libraries installed
on my system have an SONAME, so it should be fine if libinproctrace.so
does too.

As a consequence, native testing does not work anymore, since
executables do not contain the absolute path to the library anymore.  To
keep them working, we can have gdb_load_shlibs copy the library to the
test directory when testing natively.  That's done by modifying
gdb_load_shlibs.  We also have to add RPATH=$ORIGIN to executables, even
when testing natively.

I think it's a good change in general, as it reduces the differences
between testing a native and a remote target.  To further reduce those
differences, we can also always build test shared libraries with an
SONAME.

ftrace.exp and ftrace-lock.exp need to be modified slightly.  The code
checks that the IPA library is loaded using the absolute path on the
build machine.  That obviously doesn't work if the test is done
remotely, as the path will be different.  I changed the tests to only
search for the library basename (e.g. libinproctrace.so).

8 years agoImprove gdb_remote_download, remove gdb_download
Simon Marchi [Tue, 5 Apr 2016 17:59:49 +0000 (13:59 -0400)] 
Improve gdb_remote_download, remove gdb_download

This patch removes gdb_download in favor of gdb_remote_download, since
they are very close in functionality.  Also, in preparation for the
following patch about shared library handling during tests, it improves
gdb_remote_download so that it uses standard_output_file for any
destination board that is local, not only host.

If the destination board is remote, gdb_remote_download will use the
standard remote_download from DejaGnu, resulting in the file being
transferred on the remote system.

If the destination is local, gdb_remote_download will copy the file to
the standard test directory (found using standard_output_file).  Tcl's
file copy seems to handle gracefully cases where the source file is the
same as the destination, so I don't think it's necessary to check for
that case ourselves, as a previous version of the patch did.

I'd prefer to keep the name gdb_download instead of gdb_remote_download,
since I don't like the fact that gdb_remote_download implies that the
destination is remote, when it's not always the case.  However,
gdb_remote_download is used at many more places than gdb_download, so
it's easier to reuse that.  Also, since it's a wrapper around DejaGnu's
remote_download, it might be better to keep that name.  I don't know.

I ran the testsuite native, with native-gdbserver and with a
remote gdbserver, and didn't see any related failure.

8 years agoELF/LD: Avoid producing hidden and internal dynamic symbols
Maciej W. Rozycki [Tue, 5 Apr 2016 14:10:05 +0000 (15:10 +0100)] 
ELF/LD: Avoid producing hidden and internal dynamic symbols

Always turn hidden and internal symbols which have a dynamic index into
local ones.  This is required by the the ELF gABI[1]:

"A hidden symbol contained in a relocatable object must be either
removed or converted to STB_LOCAL binding by the link-editor when the
relocatable object is included in an executable file or shared object."

"An internal symbol contained in a relocatable object must be either
removed or converted to STB_LOCAL binding by the link-editor when the
relocatable object is included in an executable file or shared object."

The ELF linker usually respects this requirement, however in the case
where a dynamic symbol has been preallocated due to a reference of the
default export class aka visibility from the object being linked, and
then merged with a hidden or internal symbol definition from within the
same object, then the original export class is carried over to the
output dynamic symbol table, because while merging the generic ELF
linker only converts affected dynamic symbols to local when they are
defined or referenced by the object being linked and a dynamic object
involved in the link both at a time.

The dynamic symbol produced confuses then the dynamic loader at the run
time -- the hidden or internal export class is ignored and the symbol
follows preemption rules as with the default export class.

In the MIPS target it happens when `mips_elf_record_global_got_symbol'
creates a dynamic symbol when a call relocation is encountered.
Additionally if the undefined symbol referred by such a relocation does
specify the intended export class, then a local dynamic symbol is
created instead, which is harmless and allowed, but useless.  Normally
no local dynamic symbols are created, except for a single dummy one at
the beginning.

Correct the problem by removing the extra check for a dynamic symbol
being defined or referenced by the object being linked and a dynamic
object involved in the link both at a time.  The test cases included
cover the internal and hidden symbol cases, as well as a protected
symbol for a reference, the handling of which is unchanged by this fix.
Both cases described above are covered, that is where an internal or
hidden dynamic symbol is produced and where a local one is.

NB this change affects CRIS results where some symbols in the static
table produced in a final link are now converted from STV_HIDDEN to
STB_LOCAL.  This happens whenever the `elf_backend_hide_symbol' handler
is called, so the affected symbols must have been chosen for entering
into the dynamic symbol table, except in these test cases no such symbol
table is produced.  In fully linked binaries the static symbol table is
only used for debugging though, so such a change is fine.

missing cast, the other is const usage on global function pointers
exported from IPA: in C++, consts are static, and thus won't be
exported from the DSO (the build error was because of non-applicable
visibility("default")).
