[Valgrind-announce] Valgrind-3.11.0 is available
From: Julian Seward <jseward@ac...> - 2015-09-23 12:17:12
We are pleased to announce a new release of Valgrind, version 3.11.0,
available from http://www.valgrind.org.
3.11.0 is a feature release with many improvements and the usual
collection of bug fixes. This release adds full support for
X86/Solaris and AMD64/Solaris, improves support for Mac OS X 10.10
(Yosemite), and adds preliminary support for Mac OS X 10.11 (El
Capitan) and TileGX/Linux. Intel AVX2 support is more complete (64
bit targets only). There are many smaller refinements and new
features.
The release notes below give more details.
Our thanks to all those who contribute to Valgrind's development.
This release represents a great deal of time, energy and effort on the
part of many people.
Happy and productive debugging and profiling,
-- The Valgrind Developers
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.
