Updated devtoolset-3-valgrind packages that fix several bugs and add variousenhancements are now available for Red Hat Developer Toolset 3.1.

Valgrind is an instrumentation framework that is used for debugging memory,detecting memory leaks, and profiling applications. The devtoolset-3-valgrindpackages provide the Red Hat Developer Toolset version of Valgrind.The devtoolset-3-valgrind packages have been upgraded to upstream version3.10.1, which provides a number of bug fixes and enhancements over the previousversion. Among others: * Error messages that include stack traces can now show inline function calls ifthe DWARF debugging information format is available. These can also be used insuppressions.* Error messages concerning dubious arguments (for example, to “malloc” or”calloc”) now include a stack trace and can be used in suppressions.* The C++ demangler has been updated for better C++11 support.* The Valgrind gdbserver functionality now supports the display of thread localvariables and storage (__thread).* Three new “monitor” commands have been added to Valgrind: “v.info location<address>” to show more information about an address; “v.info stats” to showvarious Valgrind core and tool statistics; “v.set hostvisibility”, which allowsValgrind gdbserver to provide access to Valgrind internal host status andmemory. * A new command line option, “–vgdb-stop-at=event1,event2,…”, which allowsthe user to ask the Valgrind gdbserver to stop at the start of programexecution, at the end of the program execution, and when Valgrind aborts oninternal errors.* In the Valgrind memcheck tool, the client code can now selectively disable andre-enable reporting of invalid address errors in specific ranges using newclient requests.* The Valgrind memcheck tool now supports more accurate checking of system-callparameters that use uninitialized fields in structures.* In the Valgrind memcheck tool, it is now possible to disable the mismatchedchecking of memory deallocation using the “free” or “delete” functions byspecifying the new “–show-mismatched-frees=no|yes” flag, with the default valuebeing “yes”.* In the Valgrind helgrind tool, more information about race conditions andlocks is now shown in error messages as the new Valgrind gdbserver “monitor”command returns the list of locks, their location, and their status.(BZ#1163976)This update also fixes the following bugs:* Previously, Valgrind did not recognize Intel Memory Protection Extensions(MPX) instructions or instructions using the MPX bnd prefix. As a consequence,when a program that used MPX instructions was run under Valgrind, Valgrind senta SIGILL signal to terminate this program. With this update, Valgrind recognizesthe new MPX instructions and bnd prefixes. All new MPX instructions arecurrently implemented as no operation instructions, and the bnd prefix isignored. As a result, programs using MPX instructions or bnd prefixes now rununder Valgrind as if the MPX was not enabled on the CPU, and the programs are nolonger terminated in this scenario. (BZ#1146038)* Valgrind was unable to emulate a total LL cache size other than a power oftwo. Consequently, when detecting CPU caches, Valgrind refused to run thecachegrind tool with the warning message “Cache set count is not a power oftwo.” With this update, Valgrind forces down the cache size it emulates to thenearest power of two below the value detected on the system. As a result, thecachegrind tool can now be run on systems that were detected as having a CPUcache size that was not a power of two. Additionally, cachegrind returns awarning message to indicate the difference between the detected or specifiedcache size and the emulated cache size. (BZ#1151356)Users of devtoolset-3-valgrind are advised to upgrade to these updated packages,which fix these bugs and add these enhancements.
