Use address_from_register in dwarf2-frame.c:read_addr_from_reg
This patch fixes a problem that prevented use of the Dwarf unwinders on SPU,
because dwarf2-frame.c common code did not support the situation where the
stack and/or frame pointer is maintained in a *vector* register. This is
because read_addr_from_reg is hard-coded to assume that such pointers can
be read from registers via a simple get_frame_register / unpack_pointer
operation.
Now, there *is* a routine address_from_register that calls into the
appropriate tdep routines to handle pointer values in "weird" registers
like on SPU, but it turns out I cannot simply change dwarf2-frame.c to
use address_from_register. This is because address_from_register uses
value_from_register to create a (temporary) value, and that routine
at some point calls get_frame_id in order to set up that value's
VALUE_FRAME_ID entry.
However, the dwarf2-frame.c read_addr_from_reg routine will be called
during early unwinding (to unwind the frame's CFA), at which point the
frame's ID is not actually known yet! This would cause an assert.
On the other hand, we may notice that VALUE_FRAME_ID is only needed in the
value returned by value_from_register if that value is later used as an
lvalue. But this is obviously never done to the temporary value used in
address_from_register. So, if we could change address_from_register to
not call value_from_register but instead accept constructing a value
that doesn't have VALUE_FRAME_ID set, things should be fine.
To do that, we can change the value_from_register callback to accept
a FRAME_ID instead of a FRAME; the only existing uses of the FRAME
argument were either to extract its frame ID, or its gdbarch. (To
keep a way of getting at the latter, we also change the callback's
type from "f" to "m".) Together with the required follow-on changes
in the existing value_from_register implementations (including the
default one), this seems to fix the problem.
As another minor interface cleanup, I've removed the explicit TYPE
argument from address_from_register. This routine really always
uses a default pointer type, and in the new implementation it -to
some extent- relies on that fact, in that it will now no longer
handle types that require gdbarch_convert_register_p handling.

PowerPC64 ELFv2 ABI: skip global entry point code
This patch handles another aspect of the ELFv2 ABI, which unfortunately
requires common code changes.
In ELFv2, functions may provide both a global and a local entry point.
The global entry point (where the function symbol points to) is intended
to be used for function-pointer or cross-module (PLT) calls, and requires
r12 to be set up to the entry point address itself. The local entry
point (which is found at a fixed offset after the global entry point,
as defined by bits in the symbol table entries' st_other field), instead
expects r2 to be set up to the current TOC.
Now, when setting a breakpoint on a function by name, you really want
that breakpoint to trigger either way, no matter whether the function
is called via its local or global entry point. Since the global entry
point will always fall through into the local entry point, the way to
achieve that is to simply set the breakpoint at the local entry point.
One way to do that would be to have prologue parsing skip the code
sequence that makes up the global entry point. Unfortunately, this
does not work reliably, since -for optimized code- GDB these days
will not actuall invoke the prologue parsing code but instead just
set the breakpoint at the symbol address and rely on DWARF being
correct at any point throughout the function ...
Unfortunately, I don't really see any way to express the notion of
local entry points with the current set of gdbarch callbacks.
Thus this patch adds a new callback, skip_entrypoint, that is
somewhat analogous to skip_prologue, but is called every time
GDB needs to determine a function start address, even in those
cases where GDB decides to not call skip_prologue.
As a side effect, the skip_entrypoint implementation on ppc64
does not need to perform any instruction parsing; it can simply
rely on the local entry point flags in the symbol table entry.
With this implemented, two test cases would still fail to set
the breakpoint correctly, but that's because they use the construct:
gdb_test "break *hello"
Now, using "*hello" explicitly instructs GDB to set the breakpoint
at the numerical value of "hello" treated as function pointer, so
it will by definition only hit the global entry point.
I think this behaviour is unavoidable, but acceptable -- most people
do not use this construct, and if they do, they get what they
asked for ...
In one of those two test cases, use of this construct is really
not appropriate. I think this was added way back when as a means
to work around prologue skipping problems on some platforms. These
days that shouldn't really be necessary any more ...
For the other (step-bt), we really want to make sure backtracing
works on the very first instruction of the routine. To enable that
test also on powerpc64le-linux, we can modify the code to call the
test function via function pointer (which makes it use the global
entry point in the ELFv2 ABI).
gdb/ChangeLog:
* gdbarch.sh (skip_entrypoint): New callback.
* gdbarch.c, gdbarch.h: Regenerate.
* symtab.c (skip_prologue_sal): Call gdbarch_skip_entrypoint.
* infrun.c (fill_in_stop_func): Likewise.
* ppc-linux-tdep.c: Include "elf/ppc64.h".
(ppc_elfv2_elf_make_msymbol_special): New function.
(ppc_elfv2_skip_entrypoint): Likewise.
(ppc_linux_init_abi): Install them for ELFv2.
gdb/testsuite/ChangeLog:
* gdb.base/sigbpt.exp: Do not use "*" when setting breakpoint
on a function.
* gdb.base/step-bt.c: Call hello via function pointer to make
sure its first instruction is executed on powerpc64le-linux.

# On some platforms, a single function may provide multiple entry points,
# e.g. one that is used for function-pointer calls and a different one
# that is used for direct function calls.
# In order to ensure that breakpoints set on the function will trigger
# no matter via which entry point the function is entered, a platform
# may provide the skip_entrypoint callback. It is called with IP set
# to the main entry point of a function (as determined by the symbol table),
# and should return the address of the innermost entry point, where the
# actual breakpoint needs to be set. Note that skip_entrypoint is used
# by GDB common code even when debugging optimized code, where skip_prologue
# is not used.

ppc-aix core file relocation.
The current code attempts to provide relocation support when debugging
core files via the rs6000_xfer_partial method of the rs6000-nat
target_ops vector. However, this target_ops vector does not get pushed
on the target stack at all when debugging core files, thus bypassing
completely that part of the code.
This patch fixes the problem by extending corelow's core_xfer_partial
into handling the TARGET_OBJECT_LIBRARIES_AIX object.

This patch implements the new gdbarch method gdbarch_gdb_signal_to_target.
It will be used when one wants to convert between the internal GDB signal
representation (enum gdb_signal) and the target's representation.
The idea of this patch came from a chat between Pedro and I on IRC, plus
the discussion of my patches to add the new $_exitsignal convenience
variable:
<http://sourceware.org/ml/gdb-patches/2013-06/msg00452.html>
<http://sourceware.org/ml/gdb-patches/2013-06/msg00352.html>
What I did was to investigate, on the Linux kernel, which targets shared
the signal numbers definition with the generic definition, present at
<include/uapi/asm-generic/signal.h>. For the record, I used linux-3.10-rc7
as the main source of information, always looking at
<arch/<ARCH_NAME>/include/uapi/asm/signal.h>. For SIGRTMAX (which defaults
to _NSIG in most cases), I had to look at different signal-related
files, but most of them (except MIPS) were defined to 64 anyway.
Then, with all the differences in hand, I implemented the bits on each
target.

Extend SystemTap SDT probe argument parser
This patch extends the current generic parser for SystemTap SDT probe
arguments. It can be almost considered a cleanup, but the main point of
it is actually to allow the generic parser to accept multiple prefixes
and suffixes for the its operands (i.e., integers, register names, and
register indirection).
I have chosen to implement this as a list of const strings, and declare
this list as "static" inside each target's method used to initialize
gdbarch.
This patch is actually a preparation for an upcoming patch for ARM,
which implements the support for multiple integer prefixes (as defined
by ARM's asm spec). And AArch64 will also need this, for the same
reason.
This patch was regtested on all architectures that it touches (i.e.,
i386, x86_64, ARM, PPC/PPC64, s390x and IA-64). No regressions were found.

it is actually to allow the generic parser to accept multiple prefixes
and suffixes for the its operands (i.e., integers, register names, and
register indirection).
I have chosen to implement this as a list of const strings, and declare
this list as "static" inside each target's method used to initialize
gdbarch.
This patch is actually a preparation for an upcoming patch for ARM,
which implements the support for multiple integer prefixes (as defined
by ARM's asm spec). And AArch64 will also need this, for the same
reason.
This patch was regtested on all architectures that it touches (i.e.,
i386, x86_64, ARM, PPC/PPC64, s390x and IA-64). No regressions were found.

# Function used to handle a "special case" in the parser.
#
# A "special case" is considered to be an unknown token, i.e., a token
# that the parser does not know how to parse. A good example of special
# case would be ARM's register displacement syntax:
#
# [R0, #4] ;; displacing R0 by 4
#
# Since the parser assumes that a register displacement is of the form:
#
# <number> <indirection_prefix> <register_name> <indirection_suffix>
#
# it means that it will not be able to recognize and parse this odd syntax.
# Therefore, we should add a special case function that will handle this token.
#
# This function should generate the proper expression form of the expression
# using GDB\'s internal expression mechanism (e.g., \`write_exp_elt_opcode\'
# and so on). It should also return 1 if the parsing was successful, or zero
# if the token was not recognized as a special token (in this case, returning
# zero means that the special parser is deferring the parsing to the generic
# parser), and should advance the buffer pointer (p->arg).

/* Mechanism for co-ordinating the selection of a specific
architecture.
GDB targets ( *-tdep.c) can register an interest in a specific
architecture. Other GDB components can register a need to maintain
per-architecture data.
The mechanisms below ensures that there is only a loose connection
between the set-architecture command and the various GDB
2000-09-02 02:02:54 +02:00
components. Each component can independently register their need
1999-08-31 03:14:27 +02:00
to maintain architecture specific data with gdbarch.
Pragmatics:
Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
didn' t scale.
The more traditional mega-struct containing architecture specific
data for all the various GDB components was also considered. Since
2000-09-02 02:02:54 +02:00
GDB is built from a variable number of ( fairly independent)
1999-08-31 03:14:27 +02:00
components it was determined that the global aproach was not

/* Register a new architectural family with GDB.
Register support for the specified ARCHITECTURE with GDB. When
gdbarch determines that the specified architecture has been
selected, the corresponding INIT function is called.
--
The INIT function takes two parameters: INFO which contains the
information available to gdbarch about the ( possibly new)
architecture; ARCHES which is a list of the previously created
\` \` struct gdbarch'' for this architecture.
2002-04-20 19:41:18 +02:00
The INFO parameter is, as far as possible, be pre-initialized with
2006-11-10 20:20:37 +01:00
information obtained from INFO.ABFD or the global defaults.
2002-04-20 19:41:18 +02:00
The ARCHES parameter is a linked list ( sorted most recently used)
of all the previously created architures for this architecture
family. The ( possibly NULL) ARCHES->gdbarch can used to access
values from the previously selected architecture for this
2009-07-02 19:29:17 +02:00
architecture family.
1999-08-31 03:14:27 +02:00
The INIT function shall return any of: NULL - indicating that it
2000-10-27 21:17:57 +02:00
doesn' t recognize the selected architecture; an existing \` \` struct
1999-08-31 03:14:27 +02:00
gdbarch'' from the ARCHES list - indicating that the new
architecture is just a synonym for an earlier architecture ( see
gdbarch_list_lookup_by_info( ) ) ; a newly created \` \` struct gdbarch''
2000-06-10 07:37:47 +02:00
- that describes the selected architecture ( see gdbarch_alloc( ) ) .
The DUMP_TDEP function shall print out all target specific values.
Care should be taken to ensure that the function works in both the
2011-01-07 20:36:19 +01:00
multi-arch and non- multi-arch cases. */

Extend SystemTap SDT probe argument parser
This patch extends the current generic parser for SystemTap SDT probe
arguments. It can be almost considered a cleanup, but the main point of
it is actually to allow the generic parser to accept multiple prefixes
and suffixes for the its operands (i.e., integers, register names, and
register indirection).
I have chosen to implement this as a list of const strings, and declare
this list as "static" inside each target's method used to initialize
gdbarch.
This patch is actually a preparation for an upcoming patch for ARM,
which implements the support for multiple integer prefixes (as defined
by ARM's asm spec). And AArch64 will also need this, for the same
reason.
This patch was regtested on all architectures that it touches (i.e.,
i386, x86_64, ARM, PPC/PPC64, s390x and IA-64). No regressions were found.
