Release 3.12.0 (?? ????????? 201?)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Release 3.12.0 is under development, not yet released.

* ================== PLATFORM CHANGES =================

* Preliminary support for macOS 10.12 (Sierra) has been added.

* ==================== TOOL CHANGES ====================

* Memcheck:

* Helgrind:

* Callgrind:

* DRD:

n-i-bz Improved thread startup time significantly on non-Linux platforms.

* ==================== OTHER CHANGES ====================

* Replacement/wrapping of malloc/new related functions is now done not just

for system libraries by default, but for any globally defined malloc/new

related function (both in shared libraries and staticly linked alternative

malloc implementations). Dynamic (runtime) linker is excluded, though.

To only intercept malloc/new related functions in

system libraries use --soname-synonyms=somalloc=nouserintercepts (where

"nouserintercepts" can be any non-existing library name).

This new functionality is not implemented for darwin/macosx.

* The maximum number of callers in a suppression entry is now equal to

the maximum size for --num-callers (500).

Note that --gen-suppressions=yes|all similarly generate suppression

containing up to --num-callers frames.

* New and modified GDB server monitor features:

- Valgrind's gdbserver now accepts the command 'catch syscall'.

Note that you must have a GDB >= 7.11 to use 'catch syscall' with

gdbserver.

* New option --run-cxx-freeres=<yes|no> can be used to change whether

__gnu_cxx::__freeres() cleanup function is called or not. Default is

'yes'.

* Valgrind is able to read compressed debuginfo sections in two formats:

- zlib ELF gABI format with SHF_COMPRESSED flag (gcc option -gz=zlib)

- zlib GNU format with .zdebug sections (gcc option -gz=zlib-gnu)

* Modest JIT-cost improvements: the cost of instrumenting code blocks

for the most common use case (x86_64-linux, Memcheck) has been

reduced by 10%-15%.

* ==================== FIXED BUGS ====================

The following bugs have been fixed or resolved. Note that "n-i-bz"

stands for "not in bugzilla" -- that is, a bug that was reported to us

but never got a bugzilla entry. We encourage you to file bugs in

bugzilla (https://bugs.kde.org/enter_bug.cgi?product=valgrind) rather

than mailing the developers (or mailing lists) directly -- bugs that

are not entered into bugzilla tend to get forgotten about or ignored.

Release 3.11.0 (22 September 2015)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3.11.0 is a feature release with many improvements and the usual

collection of bug fixes.

This release supports X86/Linux, AMD64/Linux, ARM32/Linux,

ARM64/Linux, PPC32/Linux, PPC64BE/Linux, PPC64LE/Linux, S390X/Linux,

MIPS32/Linux, MIPS64/Linux, ARM/Android, ARM64/Android,

MIPS32/Android, X86/Android, X86/Solaris, AMD64/Solaris, X86/MacOSX

10.10 and AMD64/MacOSX 10.10. There is also preliminary support for

X86/MacOSX 10.11, AMD64/MacOSX 10.11 and TILEGX/Linux.

* ================== PLATFORM CHANGES =================

* Support for Solaris/x86 and Solaris/amd64 has been added.

* Preliminary support for Mac OS X 10.11 (El Capitan) has been added.

* Preliminary support for the Tilera TileGX architecture has been added.

* s390x: It is now required for the host to have the "long displacement"

facility. The oldest supported machine model is z990.

* x86: on an SSE2 only host, Valgrind in 32 bit mode now claims to be a

Pentium 4. 3.10.1 wrongly claimed to be a Core 2, which is SSSE3.

* The JIT's register allocator is significantly faster, making the JIT

as a whole somewhat faster, so JIT-intensive activities, for example

program startup, are modestly faster, around 5%.

* There have been changes to the default settings of several command

line flags, as detailed below.

* Intel AVX2 support is more complete (64 bit targets only). On AVX2

capable hosts, the simulated CPUID will now indicate AVX2 support.

* ==================== TOOL CHANGES ====================

* Memcheck:

- The default value for --leak-check-heuristics has been changed from

"none" to "all". This helps to reduce the number of possibly

lost blocks, in particular for C++ applications.

- The default value for --keep-stacktraces has been changed from

"malloc-then-free" to "malloc-and-free". This has a small cost in

memory (one word per malloc-ed block) but allows Memcheck to show the

3 stacktraces of a dangling reference: where the block was allocated,

where it was freed, and where it is acccessed after being freed.

- The default value for --partial-loads-ok has been changed from "no" to

"yes", so as to avoid false positive errors resulting from some kinds

of vectorised loops.

- A new monitor command 'xb <addr> <len>' shows the validity bits of

<len> bytes at <addr>. The monitor command 'xb' is easier to use

than get_vbits when you need to associate byte data value with

their corresponding validity bits.

- The 'block_list' monitor command has been enhanced:

o it can print a range of loss records

o it now accepts an optional argument 'limited <max_blocks>'

to control the number of blocks printed.

o if a block has been found using a heuristic, then

'block_list' now shows the heuristic after the block size.

o the loss records/blocks to print can be limited to the blocks

found via specified heuristics.

- The C helper functions used to instrument loads on

x86-{linux,solaris} and arm-linux (both 32-bit only) have been

replaced by handwritten assembly sequences. This gives speedups

in the region of 0% to 7% for those targets only.

- A new command line option, --expensive-definedness-checks=yes|no,

has been added. This is useful for avoiding occasional invalid

uninitialised-value errors in optimised code. Watch out for

runtime degradation, as this can be up to 25%. As always, though,

the slowdown is highly application specific. The default setting

is "no".

* Massif:

- A new monitor command 'all_snapshots <filename>' dumps all

snapshots taken so far.

* Helgrind:

- Significant memory reduction and moderate speedups for

--history-level=full for applications accessing a lot of memory

with many different stacktraces.

- The default value for --conflict-cache-size=N has been doubled to

2000000. Users that were not using the default value should

preferably also double the value they give.

The default was changed due to the changes in the "full history"

implementation. Doubling the value gives on average a slightly more

complete history and uses similar memory (or significantly less memory

in the worst case) than the previous implementation.

- The Helgrind monitor command 'info locks' now accepts an optional

argument 'lock_addr', which shows information about the lock at the

given address only.

- When using --history-level=full, the new Helgrind monitor command

'accesshistory <addr> [<len>]' will show the recorded accesses for

<len> (or 1) bytes at <addr>.

* ==================== OTHER CHANGES ====================

* The default value for the --smc-check option has been changed from

"stack" to "all-non-file" on targets that provide automatic D-I

cache coherence (x86, amd64 and s390x). The result is to provide,

by default, transparent support for JIT generated and self-modifying

code on all targets.

* Mac OS X only: the default value for the --dsymutil option has been

changed from "no" to "yes", since any serious usage on Mac OS X

always required it to be "yes".

* The command line options --db-attach and --db-command have been removed.

They were deprecated in 3.10.0.

* When a process dies due to a signal, Valgrind now shows the signal

and the stacktrace at default verbosity (i.e. verbosity 1).

* The address description logic used by Memcheck and Helgrind now

describes addresses in anonymous segments, file mmap-ed segments,

shared memory segments and the brk data segment.

* The new option --error-markers=<begin>,<end> can be used to mark the

begin/end of errors in textual output mode, to facilitate

searching/extracting errors in output files that mix valgrind errors

with program output.

* The new option --max-threads=<number> can be used to change the number

of threads valgrind can handle. The default is 500 threads which

should be more than enough for most applications.

* The new option --valgrind-stacksize=<number> can be used to change the

size of the private thread stacks used by Valgrind. This is useful

for reducing memory use or increasing the stack size if Valgrind

segfaults due to stack overflow.

* The new option --avg-transtab-entry-size=<number> can be used to specify

the expected instrumented block size, either to reduce memory use or

to avoid excessive retranslation.

* Valgrind can be built with Intel's ICC compiler, version 14.0 or later.

* New and modified GDB server monitor features:

- When a signal is reported in GDB, you can now use the GDB convenience

variable $_siginfo to examine detailed signal information.

- Valgrind's gdbserver now allows the user to change the signal

to deliver to the process. So, use 'signal SIGNAL' to continue execution

with SIGNAL instead of the signal reported to GDB. Use 'signal 0' to

continue without passing the signal to the process.

- With GDB >= 7.10, the command 'target remote'

will automatically load the executable file of the process running

under Valgrind. This means you do not need to specify the executable

file yourself, GDB will discover it itself. See GDB documentation about

'qXfer:exec-file:read' packet for more info.

* ==================== FIXED BUGS ====================

The following bugs have been fixed or resolved. Note that "n-i-bz"

stands for "not in bugzilla" -- that is, a bug that was reported to us

but never got a bugzilla entry. We encourage you to file bugs in

bugzilla (https://bugs.kde.org/enter_bug.cgi?product=valgrind) rather

than mailing the developers (or mailing lists) directly -- bugs that

are not entered into bugzilla tend to get forgotten about or ignored.

Release 3.10.1 (25 November 2014)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3.10.1 is a bug fix release. It fixes various bugs reported in 3.10.0

and backports fixes for all reported missing AArch64 ARMv8 instructions

and syscalls from the trunk. If you package or deliver 3.10.0 for others

to use, you might want to consider upgrading to 3.10.1 instead.

The following bugs have been fixed or resolved. Note that "n-i-bz"

stands for "not in bugzilla" -- that is, a bug that was reported to us

but never got a bugzilla entry. We encourage you to file bugs in

bugzilla (https://bugs.kde.org/enter_bug.cgi?product=valgrind) rather

than mailing the developers (or mailing lists) directly -- bugs that

are not entered into bugzilla tend to get forgotten about or ignored.

Release 3.10.0 (10 September 2014)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3.10.0 is a feature release with many improvements and the usual

collection of bug fixes.

This release supports X86/Linux, AMD64/Linux, ARM32/Linux, ARM64/Linux,

PPC32/Linux, PPC64BE/Linux, PPC64LE/Linux, S390X/Linux, MIPS32/Linux,

MIPS64/Linux, ARM/Android, MIPS32/Android, X86/Android, X86/MacOSX 10.9

and AMD64/MacOSX 10.9. Support for MacOSX 10.8 and 10.9 is

significantly improved relative to the 3.9.0 release.

* ================== PLATFORM CHANGES =================

* Support for the 64-bit ARM Architecture (AArch64 ARMv8). This port

is mostly complete, and is usable, but some SIMD instructions are as

yet unsupported.

* Support for little-endian variant of the 64-bit POWER architecture.

* Support for Android on MIPS32.

* Support for 64bit FPU on MIPS32 platforms.

* Both 32- and 64-bit executables are supported on MacOSX 10.8 and 10.9.

* Configuration for and running on Android targets has changed.

See README.android in the source tree for details.

* ================== DEPRECATED FEATURES =================

* --db-attach is now deprecated and will be removed in the next

valgrind feature release. The built-in GDB server capabilities are

superior and should be used instead. Learn more here:

http://valgrind.org/docs/manual/manual-core-adv.html#manual-core-adv.gdbserver

* ==================== TOOL CHANGES ====================

* Memcheck:

- Client code can now selectively disable and re-enable reporting of

invalid address errors in specific ranges using the new client

requests VALGRIND_DISABLE_ADDR_ERROR_REPORTING_IN_RANGE and

VALGRIND_ENABLE_ADDR_ERROR_REPORTING_IN_RANGE.

- Leak checker: there is a new leak check heuristic called

"length64". This is used to detect interior pointers pointing 8

bytes inside a block, on the assumption that the first 8 bytes

holds the value "block size - 8". This is used by

sqlite3MemMalloc, for example.

- Checking of system call parameters: if a syscall parameter

(e.g. bind struct sockaddr, sendmsg struct msghdr, ...) has

several fields not initialised, an error is now reported for each

field. Previously, an error was reported only for the first

uninitialised field.

- Mismatched alloc/free checking: a new flag

--show-mismatched-frees=no|yes [yes] makes it possible to turn off

such checks if necessary.

* Helgrind:

- Improvements to error messages:

o Race condition error message involving heap allocated blocks also

show the thread number that allocated the raced-on block.

o All locks referenced by an error message are now announced.

Previously, some error messages only showed the lock addresses.

o The message indicating where a lock was first observed now also

describes the address/location of the lock.

- Helgrind now understands the Ada task termination rules and

creates a happens-before relationship between a terminated task

and its master. This avoids some false positives and avoids a big

memory leak when a lot of Ada tasks are created and terminated.

The interceptions are only activated with forthcoming releases of

gnatpro >= 7.3.0w-20140611 and gcc >= 5.0.

- A new GDB server monitor command "info locks" giving the list of

locks, their location, and their status.

* Callgrind:

- callgrind_control now supports the --vgdb-prefix argument,

which is needed if valgrind was started with this same argument.

* ==================== OTHER CHANGES ====================

* Unwinding through inlined function calls. Stack unwinding can now

make use of Dwarf3 inlined-unwind information if it is available.

The practical effect is that inlined calls become visible in stack

traces. The suppression matching machinery has been adjusted

accordingly. This is controlled by the new option

--read-inline-info=yes|no. Currently this is enabled by default

only on Linux and Android targets and only for the tools Memcheck,

Helgrind and DRD.

* Valgrind can now read EXIDX unwind information on 32-bit ARM

targets. If an object contains both CFI and EXIDX unwind

information, Valgrind will prefer the CFI over the EXIDX. This

facilitates unwinding through system libraries on arm-android

targets.

* Address description logic has been improved and is now common

between Memcheck and Helgrind, resulting in better address

descriptions for some kinds of error messages.

* Error messages about dubious arguments (eg, to malloc or calloc) are

output like other errors. This means that they can be suppressed

and they have a stack trace.

* The C++ demangler has been updated for better C++11 support.

* New and modified GDB server monitor features:

- Thread local variables/storage (__thread) can now be displayed.

- The GDB server monitor command "v.info location <address>"

displays information about an address. The information produced

depends on the tool and on the options given to valgrind.

Possibly, the following are described: global variables, local

(stack) variables, allocated or freed blocks, ...

- The option "--vgdb-stop-at=event1,event2,..." allows the user to

ask the GDB server to stop at the start of program execution, at

the end of the program execution and on Valgrind internal errors.

- A new monitor command "v.info stats" shows various Valgrind core

and tool statistics.

- A new monitor command "v.set hostvisibility" allows the GDB server

to provide access to Valgrind internal host status/memory.

* A new option "--aspace-minaddr=<address>" can in some situations

allow the use of more memory by decreasing the address above which

Valgrind maps memory. It can also be used to solve address

conflicts with system libraries by increasing the default value.

See user manual for details.

* The amount of memory used by Valgrind to store debug info (unwind

info, line number information and symbol data) has been

significantly reduced, even though Valgrind now reads more

information in order to support unwinding of inlined function calls.

* Dwarf3 handling with --read-var-info=yes has been improved:

- Ada and C struct containing VLAs no longer cause a "bad DIE" error

- Code compiled with

-ffunction-sections -fdata-sections -Wl,--gc-sections

no longer causes assertion failures.

* Improved checking for the --sim-hints= and --kernel-variant=

options. Unknown strings are now detected and reported to the user

as a usage error.

* The semantics of stack start/end boundaries in the valgrind.h

VALGRIND_STACK_REGISTER client request has been clarified and

documented. The convention is that start and end are respectively

the lowest and highest addressable bytes of the stack.

* ==================== FIXED BUGS ====================

The following bugs have been fixed or resolved. Note that "n-i-bz"

stands for "not in bugzilla" -- that is, a bug that was reported to us

but never got a bugzilla entry. We encourage you to file bugs in

bugzilla (https://bugs.kde.org/enter_bug.cgi?product=valgrind) rather

than mailing the developers (or mailing lists) directly -- bugs that

are not entered into bugzilla tend to get forgotten about or ignored.
