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).

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.

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.

Fix PR gdb/19858: GDB doesn't register the JIT libraries on attach
Ref: https://sourceware.org/ml/gdb/2016-03/msg00023.html
GDB currently fails to fetch the list of already-registered JIT
modules on attach.
Nothing is calling jit_inferior_init, which is what is responsible for
walking the JIT object list at init time.
Despite the misleading naming, jit_inferior_created_hook ->
jit_inferior_init is only called when the inferior execs.
This regressed with the fix for PR gdb/13431 (
03bef283c2d3):
https://sourceware.org/ml/gdb-patches/2012-02/msg00023.html which
removed the inferior_created (jit_inferior_created_observer)
observer.
Adding an inferior_created observer back fixes the issue.
In turn, this exposes a bug in jit_breakpoint_re_set_internal as well,
which is returning the wrong result when we already have the
breakpoint at the right address.

IPA: Add alloc_jump_pad_buffer target hook.
Targets may have various requirements on the required location of the jump
pad area. Currently IPA allocates it at the lowest possible address,
so that it is reachable by branches from the executable. However, this
fails on powerpc, which has executable link address (0x10000000) much
larger than branch reach (+/- 32MiB).
This makes jump pad buffer allocation a target hook instead. The current
implementations are as follows:
- i386 and s390: Branches can reach anywhere, so just mmap it. This
avoids the linear search dance.
- x86_64: Branches have +/-2GiB of reach, and executable is loaded low,
so just call mmap with MAP_32BIT. Likewise avoids the linear search.
- aarch64: Branches have +-128MiB of reach, executable loaded at 4MiB.
Do a linear search from 4MiB-size downwards to page_size.
- s390x: Branches have +-4GiB of reach, executable loaded at 2GiB.
Do like on aarch64.

Don't override definition a shared object by one in a later shared object.
In PR 16979, a reference to malloc is being resolved to an unversioned
reference in libmalloc.so. When linked with --as-needed, however, the
dynamic table does not list libmalloc.so as a DT_NEEDED library.
If we have a reference to an unversioned symbol in a shared object,
and we later see a versioned definition in another shared object, we
were overriding the first definition with the second in the process of
defining the default version. As a result, we no longer think that the
first shared object was actually needed to resolve any symbols, and we
don't list it as a DT_NEEDED library.

gdbserver: Handle 'v' packet while processing qSymbol.
On powerpc64, qSymbol query may require gdb to read a function
descriptor, sending a vFile packet to gdbserver. Thus, we need
to handle 'v' packet in look_up_one_symbol.
vFile replies may be quite long, and require reallocating own_buf.
Since handle_v_requests assumes the buffer is the static global own_buf
from server.c and reallocates it, we need to make own_buf global and
use it from look_up_one_symbol instead of using our own auto variable.
I've also done the same change in relocate_instruction, just in case.
On gdb side, in remote_check_symbols, rs->buf may be clobbered by vFile
handling, yet we need its contents for the reply (the symbol name is
stored there). Allocate a new buffer instead.
This broke fast tracepoints on powerpc64, due to errors in reading IPA
symbols.

gdbserver/s390: Add fast tracepoint support.
Fast tracepoints will only work on 6-byte intructions, and assume at least
a z900 CPU. s390 also has 4-byte jump instructions, which also work on
pre-z900, but their range is limitted to +-64kiB, which is not very useful
(and wouldn't work at all with current jump pad allocation).
There's a little problem with s390_relocate_instruction function: it
converts BRAS/BRASL instructions to LARL of the return address + JG
to the target address. On 31-bit, this sets the high bit of the target
register to 0, while BRAS/BRASL would set it to 1. While this is not
a problem when the result is only used to address memory, it could
possibly break something that expects to compare such addresses for
equality without first masking the bit off. In particular, I'm not sure
whether leaving the return address high bit unset is ABI-compliant
(could confuse some unwinder?). If that's a problem, it could be fixed
by handling it in the jump pad (since at that point we can just modify
the GPRs in the save area without having to worry about preserving
CCs and only having that one GPR to work with - I'm not sure if it's
even possible to set the high bit with such constraints).

make md_parse_option () take a const char *
This is mostly just adding const in many places, however there are a couple
interesting things. We need to add casts in tc-s390.c and tc-cris.c because
they have functions that assign to input_line_pointer an argument that
sometimes comes from md_parse_option. Presumably this is safe because those
targets never pass literals to md_parse_option (), but this code should
probably be improved in the future. Also xtensa passes the argument to strtoll
which is a rather odd function, it takes a const char * as argument and returns
a pointer into that string as a char * through an out argument, but we can work
around that by adding more variables.
