Changelog for valgrind-3.22.0-5.1.i586.rpm :

* Mon Feb 05 2024 Andreas Schwab - VEX-x86-nop-pattern.patch: bko#478624 - Valgrind incompatibility with binutils-2.42 on x86 with new nop patterns (unhandled instruction bytes: 0x2E 0x8D 0xB4 0x26)
* Fri Nov 24 2023 Dirk Müller - update to 3.22.0: (jsc#PED-5442):
* Memcheck now tests and warns about the values used for alignment and size. These apply to various functions: memalign, posix_memalign and aligned_alloc in C and various overloads of operators new and delete in C++. The kinds of error that can be detected are - invalid alignment, for instance the alignment is usually required to be a power of 2 - mismatched alignment between aligned allocation and aligned deallocation - mismatched size when sized delete is used - bad size for functions that have implementation defined behaviour when the requested size is zero
* many bug fixes, see https://valgrind.org/docs/manual/dist.news.html

* Thu May 18 2023 Dirk Müller - update to 3.21.0:
* When GDB is used to debug a program running under valgrind using the valgrind gdbserver, GDB will automatically load some python code provided in valgrind defining GDB front end commands corresponding to the valgrind monitor commands.
* These GDB front end commands accept the same format as the monitor commands directly sent to the Valgrind gdbserver. These GDB front end commands provide a better integration in the GDB command line interface, so as to use for example GDB auto-completion, command specific help, searching for a command or command help matching a regexp, ... For relevant monitor commands, GDB will evaluate arguments to make the use of monitor commands easier. For example, instead of having to print the address of a variable to pass it to a subsequent monitor command, the GDB front end command will evaluate the address argument.
* The vgdb utility now supports extended-remote protocol when invoked with --multi. In this mode the GDB run command is supported. Which means you don\'t need to run gdb and valgrind from different terminals.
* The behaviour of realloc with a size of zero can now be changed for tools that intercept malloc. Those tools are memcheck, helgrind, drd, massif and dhat. Realloc implementations generally do one of two things - free the memory like free() and return NULL (GNU libc and ptmalloc). - either free the memory and then allocate a minimum sized block or just return the original pointer. Return NULL if the allocation of the minimum sized block fails (jemalloc, musl, snmalloc, Solaris, macOS).
* When Valgrind is configured and built it will try to match the OS and libc behaviour. However if you are using a non-default library to replace malloc and family (e.g., musl on a glibc Linux or tcmalloc on FreeBSD) then you can use a command line option to change the behaviour of Valgrind: - -realloc-zero-bytes-frees=yes|no [yes on Linux glibc, no otherwise]

* Fri Jun 19 2020 Michal Suchanek - Use autopatch - Change armv6-support.diff to a/b format
* Fri Jun 19 2020 Dirk Mueller - update to 3.16.0:
* Many bugfixes, too many to list here, see NEWS file - The implicit memcpy done by each call to realloc now counts towards the read and write counts of resized heap blocks, making those counts higher and more accurate. - cg_annotate\'s --auto and --show-percs options now default to \'yes\', because they are usually wanted. - callgrind_annotate\'s --auto and --show-percs options now default to \'yes\', because they are usually wanted. - The command option --collect-systime has been enhanced to specify the unit used to record the elapsed time spent during system calls. The command option now accepts the values no|yes|msec|usec|nsec, where yes is a synonym of msec. When giving the value nsec, the system cpu time of system calls is also recorded. - Several memcheck options are now dynamically changeable. Use valgrind --help-dyn-options to list them. - The release 3.15 introduced a backward incompatible change for some suppression entries related to preadv and pwritev syscalls. When reading a suppression entry using the unsupported 3.14 format, valgrind will now produce a warning to say the suppression entry will not work, and suggest the needed change. - Significantly fewer false positive errors on optimised code generated by Clang and GCC. In particular, Memcheck now deals better with the situation where the compiler will transform C-level \"A && B\" into \"B && A\" under certain circumstances (in which the transformation is valid). Handling of integer equality/non-equality checks on partially defined values is also improved on some architectures. - The exprimental Stack and Global Array Checking tool has been removed. It only ever worked on x86 and amd64, and even on those it had a high false positive rate and was slow. An alternative for detecting stack and global array overruns is using the AddressSanitizer (ASAN) facility of the GCC and Clang compilers, which require you to rebuild your code with -fsanitize=address. - Option -T tells vgdb to output a timestamp in the vgdb information messages. - The gdbserver monitor commands that require an address and an optional length argument now accepts the alternate \'C like\' syntax \"address[length]\". For example, the memcheck command \"monitor who_points_at 0x12345678 120\" can now also be given as \"monitor who_points_at 0x12345678[120]\". - 001-Add-newer-constants-for-prctl-syscall.patch 0001-Fix-makefile-consistency-check.patch 0001-s390x-Add-CPU-model-for-z15.patch 0001-s390x-Add-models-z14-and-z14-ZR1.patch 0001-s390x-Clean-up-s390-check-opcodes.pl.patch 0001-Add-newer-constants-for-prctl-syscall.patch 0002-Add-support-for-PR_CAPBSET_READ-and-_DROP-syscalls.patch: dropped as those patches were from upstream and are already in 3.16.0 - add 0001-Power-PC-Fix-extraction-of-the-L-field-for-sync-inst.patch (bsc#1173135)
