Fix an assertion in the address space manager. BZ #345887.
The VG_(extend_stack) call needs to be properly guarded because the
passed-in address is not necessarily part of an extensible stack
segment. And an extensible stack segment is the only thing that
function should have to deal with.
Previously, the function VG_(am_addr_is_in_extensible_client_stack)
was introduced to guard VG_(extend_stack) but it was not added in all
places it should have been.
Also, extending the client stack during signal delivery (in sigframe-common.c)
was simply calling VG_(extend_stack) hoping it would do the right thing.
But that was not always the case. The new testcase
none/tests/linux/pthread-stack.c exercises this (3.10.1 errors out on it).
Renamed ML_(sf_extend_stack) to ML_(sf_maybe_extend_stack) and add
proper guard logic for VG_(extend_stack).

Followup to r14974. That revision oversimplified a condition, part
of which was presumed to be redundant but wasn't. This caused code
to hang due to an infinite signal-delivery loop. Observed and

Add VG_(am_is_bogus_client_stack_pointer)(Addr).
The function is used in VG_(client_syscall) to avoid extending the stack
when it is clear that the current value of the stack pointer does not
point into a segment that looks like a stack segment.
See the comments in the code there.
As a side effect of this we can now revert r15018 which increased
the stack size of the alternate stack in memcheck/tests/sigaltstack.c.
The reason is that the belief at the time: "alternate stack is too small"
was not correct. What instead happened was that VG_(client_syscall) called
VG_(extend_stack) without need (the syscall was tgkill) and the new stack
pointer happened to be in a file segment.
In other words: the current stack pointer was still within the alternate
stack, i.e. the alternate stack was (barely) large enough.

Use wrapper functions VG_(malloc) and friends consistently across the
board (instead of e.g. VG_(arena_malloc)(VG_AR_CORE,...). This change
also benefits static analysers. We can tell tools that VG_(malloc) allocates
and VG_(free) deallocates and that they are a pair. But we cannot do that for
arena_malloc/free.
Also provide a wrapper VG_(realloc_shrink).

This commit is for Bugzilla 334834. The Bugzilla contains patch 2 of 3
to add PPC64 LE support. The other two patches can be found in Bugzillas
334384 and 334836.
POWER PC, add the functional Little Endian support, patch 2
The IBM POWER processor now supports both Big Endian and Little Endian.
The ABI for Little Endian also changes. Specifically, the function
descriptor is not used, the stack size changed, accessing the TOC
changed. Functions now have a local and a global entry point. Register
r2 contains the TOC for local calls and register r12 contains the TOC
for global calls. This patch makes the functional changes to the
Valgrind tool. The patch makes the changes needed for the
none/tests/ppc32 and none/tests/ppc64 Makefile.am. A number of the
ppc specific tests have Endian dependencies that are not fixed in
this patch. They are fixed in the next patch.
Per Julian's comments renamed coregrind/m_dispatch/dispatch-ppc64-linux.S
to coregrind/m_dispatch/dispatch-ppc64be-linux.S Created new file for LE
coregrind/m_dispatch/dispatch-ppc64le-linux.S. The same was done for
coregrind/m_syswrap/syscall-ppc-linux.S.

This commit is for Bugzilla 334384. The Bugzilla contains patch 1 of 3
to add PPC64 LE support. The other two patches can be found in Bugzillas
334834 and 334836. The commit does not have a VEX commit associated with it.
POWER PC, add initial Little Endian support
The IBM POWER processor now supports both Big Endian and Little Endian.
This patch renames the #defines with the name ppc64 to ppc64be for the BE
specific code. This patch adds the Little Endian #define ppc64le to the
Additionally, a few functions are renamed to remove BE from the name if the
function is used by BE and LE. Functions that are BE specific have BE put
in the name.
The goals of this patch is to make sure #defines, function names and
variables consistently use PPC64/ppc64 if it refers to BE and LE,
PPC64BE/ppc64be if it is specific to BE, PPC64LE/ppc64le if it is LE
specific. The patch does not break the code for PPC64 Big Endian.
The test files memcheck/tests/atomic_incs.c, tests/power_insn_available.c
and tests/power_insn_available.c are also updated to the new #define
definition for PPC64 BE.

Fix 316535 Use of |signed int| instead of (unsigned) |size_t| in messages...
* when SEGV trapped, report the main thread size as an unsigned size_t
* Similar for memcheck overlap errors
For example, for the 2 calls:
memcpy(&a, &a, 2147483648UL);
memcpy(&a, &a, -1); // silently accepted by gcc 4.4.4 -Wall
// while the 3rd arg is supposed to be a size_t
we now obtain (on a 32 bit system)
Source and destination overlap in memcpy(0xbe97113f, 0xbe97113f, 2147483648)
Source and destination overlap in memcpy(0xbef6d13f, 0xbef6d13f, 4294967295)
instead of
Source and destination overlap in memcpy(0xbe8e012f, 0xbe8e012f, -2147483648)
Source and destination overlap in memcpy(0xbe8e012f, 0xbe8e012f, -1)
Do not ask me why
memcpy(&a, &a, -1);
is supposed to be accepted/acceptable/valid code.

are always to be delivered (as explained by the following

Before printing a back-trace make sure that page containing the
address stored in the stack pointer is mapped. Fixes a corner case.

add some .globl or used attribute to avoid link failures with gold linker + LTO
When doing experiment with gcc 4.7.0 and link time optimisation,
encountered link failures on amd64 which were solved by adding
.globl and used attribute.
=> added .globl in similar places for arm/x86/ppc32/s390.
Did not touch darwin (which asm seems somewhat different).

Fix bug 297078 gdbserver signal handling problems caused by diff vki nr/gdb nr and
non reset of "C-ontinued" signal
* To allow vki signame to be used in debuglog:
- pub_core_signals.h : added prototype for Char *VG_(signame)
- m_signals.c : changed static const Char *signame(Int sigNo)
to const Char *VG_(signame)(Int sigNo)
* valgrind-low.c : when the signal to report to gdb has
been reported, clear it so that it is not reported anymore
afterwards.
* m_gdbserver.c: when checking in pass_signals if signal
can be passed without gdb interaction, do a conversion
from vki nr to gdb nr when indexing
(as pass_signals[] is indexed by gdb_nr).
* various gdbserver files:
- used vki_ prefix for some args and variables to clarify
- better debuglog tracing
* modified nlpasssigalrm.vgtest to test SIGCHLD signal
handling followed by a break (to see SIGTRAP is properly
given to gdb).

There were some easy-to-resolve conflicts.
Then I had to fix up coregrind/link_tool_exe*.in -- those files had been
added independently on both the trunk and the branch, AFAICT. I just
overwrote the trunk versions with the branch versions.

Output tweaks:
- Always print a blank line after significant messages (eg. errors). This
makes the handling of blank lines much simpler.
- Don't print full stops at the end of messages. We mostly don't do it, so
I got rid of all the remaining ones I could find for consistency.
- Use --leak-check=full rather than --leak-check=yes, for consistency with
docs and other messages.
- Update partiallydefinedeq.stderr.exp2 for older changes.
This commit only updates the code. Test updates will follow shortly. (I'm
separating them so the code changes aren't swamped by the test changes in
the SVN logs.)

Merge coregrind/ changes from branches/MESSAGING_TIDYUP r10464.
This commit tidies up and rationalises what could be called the
"messaging" system -- that part of V to do with presenting output to
the user. In particular it brings significant improvements to XML
output.
Changes are:
* XML and normal text output now have separate file descriptors,
which solves longstanding problems for XML consumers caused by
the XML output getting polluted by unexpected non-XML output.
* This also means that we no longer have to hardwire all manner
of output settings (verbosity, etc) when XML is requested.
* The XML output format has been revised, cleaned up, and made
more suitable for use by error detecting tools in general
(various Memcheck-specific features have been removed). XML
output is enabled for Ptrcheck and Helgrind, and Memcheck is
updated to the new format.
* One side effect is that the behaviour of VG_(message) has been
made to be consistent with printf: it no longer automatically
adds a newline at the end of the output. This means multiple
calls to it can be used to build up a single line message; or a
single call can write a multi-line message. The ==pid==
preamble is automatically inserted at each newline.
* VG_(message)(Vg_UserMsg, ..args..) now has the abbreviated form
VG_(UMSG)(..args..); ditto VG_(DMSG) for Vg_DebugMsg and
VG_(EMSG) for Vg_DebugExtraMsg. A couple of other useful
printf derivatives have been added to pub_tool_libcprint.h,
most particularly VG_(vcbprintf).
* There's a small change in the core-tool interface to do with
error handling: VG_(needs_tool_errors) has a new method
void (*before_pp_Error)(Error* err) which, if non-NULL, is
called just before void (*pp_Error)(Error* err). This is to
give tools the chance to look at errors before any part of them
is printed, so they can print any XML preamble they like.
* coregrind/m_errormgr.c has been overhauled and cleaned up, and
is a bit simpler and more commented. In particular pp_Error
and VG_(maybe_record_error) are significantly changed.
The diff is huge, but mostly very boring. Most of the changes
are of the form
- VG_(message)(Vg_UserMsg, "this is a message %d", n);
+ VG_(message)(Vg_UserMsg, "this is a message %d\n", n);
Unfortunately as a result of this, it touches a large number
of source files.

Merge in branches/DCAS.
This branch adds proper support for atomic instructions, proper in the
sense that the atomicity is preserved through the compilation
pipeline, and thus in the instrumented code.
These changes track the IR changes added by vex r1901. They primarily
update the instrumentation functions in all tools to handle the
changes, with the exception of exp-ptrcheck, which needs some further
work in order to be able to run threaded code.

I tried using 'svn merge' to do the merge but it did a terrible job and
there were bazillions of conflicts. So instead I just took the diff between
the branch and trunk at r10155, applied the diff to the trunk, 'svn add'ed
the added files (no files needed to be 'svn remove'd) and committed.

relatively minor extensions to m_debuginfo, a major overhaul of
m_debuginfo/readdwarf3.c to get its space usage under control, and
changes throughout the system to enable heap-use profiling.
The majority of the merged changes were committed into

Add a new method VG_(record_depth_1_ExeContext), a trivial derivative
of VG_(record_ExeContext), which just records the first stack frame
but does not attempt to unwind the (guest) stack. This is useful in
situations where we suspect unwinding the stack might cause a
segfault.
Use this in m_signals, when getting a backtrace following a guest
segfault.

Improve handling of programs which require very large main thread
stacks. Instead of hardwiring the main thread stack to a max of 16MB
and segfaulting the app beyond that point, allow the user to specify
the main stack size using the new flag --main-stacksize=<number>.
If said flag is not present, the current default, which is "MIN(16GB,
current ulimit -s value)", is used.

- add AIX definitions for VG_UCONTEXT_INSTR_PTR et al
- add abstractions VKI_SIGINFO_si_addr and VKI_SIGINFO_si_pid
to enable the rest of the code to be uniform
- track other minor changes: SysRes, VG_(am_find_nsegment)
constness, rearrangement of VG_(sigtimedwait).

Create a new module, m_vki, and move all knowledge about the kernel
interface, except for the syscall numbers, into that. Mostly this
means moving include/vki-*.h to include/vki/vki-*.h.
include/pub_tool_basics.h previously dragged in the entire kernel
interface. I've done away with that, so that modules which need to
see the kernel interface now have to include pub_{core,tool}_vki.h
explicitly. This is why there are many modified .c files -- they have
all acquired an extra #include line.
This certainly breaks all platforms except x86. Will fix shortly.

Hmm. Perhaps all those top-level pieces of assembly weren't such a
clever idea. There's no reason to assume the assembler is in
.text-mode when it encounters them, and as gcc 2.96 rudely
demonstrates, sometimes it isn't. So put .text in front of all of
them.

This commit merges in changes from branches/ASPACEM (specifically,
changes from r4341 through r4787 inclusive). That branch is now dead.
Please do not commit anything else to it.
For the most part the merge was not troublesome. The main areas of
uncertainty are:
- build system: I had to import by hand Makefile.core-AM_CPPFLAGS.am
and include it in a couple of places. Building etc seems to still
work, but I haven't tried building the documentation.
- syscall wrappers: Following analysis by Greg & Nick, a whole lot of
stuff was moved from -generic to -linux after the branch was created.
I think that is satisfactorily glued back together now.
- Regtests: although this appears to work, no .out files appear, which
is strange, and makes it hard to diagnose regtest failures. In
particular memcheck/tests/x86/scalar.stderr.exp remains in a
conflicted state.
- amd64 is broken (slightly), and ppc32 will be unbuildable. I'll
attend to the former shortly.

Incorporate a patch from Craig Chaney which gives better stack
snapshots on ppc32-linux in the presence of functions subject to
leaf-function optimisations.
At the same time, simplify the stack unwinding logic by basically
implementing it separately for each target. Having a single piece of
logic for amd64 and x86 was tenable, but merging ppc32 into it is too
confusing. So now there is an x86/amd64 unwinder and a ppc32
unwinder.
This requires plumbing a link-register value into
VG_(get_StackTrace2), and that in turn requires passing it around
several other stack-trace-related functions. Hence 7 changed files.

Make VG_(kill_self) use kill to send the signal, not tkill, as we are
sending it to the whole process not a single thread.
This routine is only used when we absolutely want to terminate
valgrind and as things stand it fails if called from anything other
than the initial thread as it winds up sending the signal to the main
thread only and that typically doesn't even exist any more so we
fall through and panic.

Declare my_sigreturn as static. This is correct in so much as it isn't
used anywhere else, but it does cause gcc to issue a warning because
it doesn't realised that the assembly code has defined the function.
The reason for changing it to static despite the warning is that when
it is declared extern PIE builds break on amd64 because gcc generates
code that does a load from the address of the my_sigreturn symbol to
get address of the function instead of just computing the address of
the symbol. In other words it generates this:
mov -212(%rip), %rax
to get the address of the function instead of this:
lea -212(%rip), %rax
Obviously this breaks things because we store the wrong address as
the signal restorer when installing the signal handler...

Don't #include pub_core_debuginfo.h in pub_core_aspacemgr.h. So have
to #include it explicitly in lots of other places, but at least the
dependency is clear now.

Finally, valgrind on ppc32.
Plenty still to do, but simple programs like ls seem to run ok
Thanks, Paul, for having your ppc port of valgrind 2.4 to work from!

Moved VG_(start_debugger) out of m_main.c into its own module,
m_debugger. This removes the dependence of m_signals.c and m_errormgr.c
on m_main.c. It required also moving VG_(clexecfd) out of m_main.c; I put
it in m_libcproc.c which seemed like an ok-but-not-great choice.

Final commit for the initial modularisation pass:
- Broke part of m_scheduler off into a new module m_threadstate. It
contains ThreadState, VG_(threads)[] and some basic operations on the
thread table. All simple stuff, the complex stuff stays in m_scheduler.
This avoids lots of circular dependencies between m_scheduler and other
modules.
- Managed to finally remove core.h and tool.h, double hurrah!
- Introduced pub_tool_basics.h and pub_core_basics.h, one of which is
include by every single C file.
- Lots of little cleanups and changes related to the above.
- I even did a small amount of documentation updating.

Renamed the m_syscalls module m_syswrap, which better describes what it
does and better distinguishes it from m_syscall. Did everything for this
except renaming the m_syscalls/ directory -- I'll do that shortly, I don't
think Subversion can handle renaming a directory and files within that
directory at the same time.

A major overhaul of all machinery to do with syscalls, but mostly of
the m_syscalls module. Fundamentally the aim of the overhaul is to
clean up the logic and abstractions surrounding syscalls in order that
we can cleanly support ppc32 and other new targets. Aims in detail:
* To further decouple the syscall PRE/POST wrappers from specifics of
how those values are stored on a given platform. The wrappers look
the same as they did before, mostly (eg, references to ARGn and
RES are unchanged), but now those macros refer to values in structs
SyscallArgs and SyscallStatus (see priv_types_n_macros.h).
* Complete overhaul of the driver logic for syscalls. The resulting
logic is algorithmically identical to what we had before, but is
more documented, and deals with moving arg/result data between
platform specific representations and the canonical forms in
structs SyscallArgs and SyscallStatus.
* Also as a result of this change, remove problems in the old logic
due to assignments of RES in PRE wrappers trashing the ARGs whilst
we still need to see them.
* Lots of other cleanups and documentation. There is extensive
commentary in syscalls-main.c.
The driver logic has been placed in its own file, syscalls-main.c.
New/deleted files in m_syscalls:
* syscalls.c is divided up into syscalls-main.c, containing driver
logic, and syscalls-generic.c, containing generic Unix wrappers.
* priv_syscalls.h is chopped up into priv_types_n_macros.h
and priv_syscalls-{generic,main}.h.
------------
All the above changes are in m_syscalls. However there is one
system-wide change as a result of all this.
The x86-linux assumption that syscall return values in the range -4095
.. -1 are errors and all others are values, has been done away with
everywhere. Instead there is a new basic type SysRes which holds a
system call result in a platform-neutral way.
Everywhere that previously an Int would have held a system call
result, there is now a SysRes in its place.
------------
Almost everything works on SuSE 9.1 (LinuxThreads) again. NPTL will
still be majorly broken; I will commit fixes shortly. AMD64 is also
totalled. I will get to that too.

Modularised assertions and panics in m_libcassert.
As part of this, killed the VG_STRINGIFY macro, which was used to expand
out names like "VG_(foo)" and "vgPlain_foo" in assertion failure
messages. This is good since we actually want the "VG_(foo)" form used
in these messages.

Started modularising vg_mylibc. Put all the standalone stuff -- ie. not
relying on any other modules -- in m_libcbase.
Also converted the 'size' parameters to functions like VG_(memcpy) and
VG_(strncpy) from Int to SizeT, as they should be.
Also removed VG_(atoll16) and VG_(toupper), which weren't being used.
Also made VG_(atoll36) less flexible -- it now only does base-36 numbers
instead of any base in the range 2..36, since base-36 is the only one we
need. As part of that, I fixed a horrible bug in it which caused it to
return incorrect answers for any number containing the digits 'A'..'I'!
(Eg. for "A; it would return 17 instead of 10!)
Had to disable the assertions in VG_(string_match), since this module can't
see vg_assert, which wasn't ideal but also isn't a disaster.

Whitespace/comment-only changes, to serve as placeholder for the last commit
which I put the wrong log message in for. The log message should have been:
Clean up VG_(core_panic_at)() -- pass it ip/sp/fp rather than a
StackTrace. This allows m_signals.c to not have to know about
m_stacktrace.c, nor does core.h need to import pub_core_stacktrace.h any
more. (Also fixed a bug that was preventing vg_assert2's extra string
from being printed.)
Also moved VG_DEEPEST_BACKTRACE out of core.h into pub_core_execontext.h.
