Memory Management Debugger

Edit Package valgrind

Valgrind checks all memory operations in an application, like read,
write, malloc, new, free, and delete. Valgrind can find uses of
uninitialized memory, access to already freed memory, overflows,
illegal stack operations, memory leaks, and any illegal
new/malloc/free/delete commands. Another program in the package is
"cachegrind," a profiler based on the valgrind engine.

To use valgrind you should compile your application with "-g -O0"
compiler options. Afterwards you can use it with:

valgrind --tool=memcheck --sloppy-malloc=yes --leak-check=yes
--db-attach=yes my_application, for example.

More valgrind options can be listed via "valgrind --help". There is
also complete documentation in the /usr/share/doc/packages/valgrind/
directory. A debugged application runs slower and needs much more
memory, but is usually still usable. Valgrind is still in development,
but it has been successfully used to optimize several KDE applications.

- update to 3.23.0 (jsc#PED-10260):
  * Added ARM64 support for FreeBSD.
  * ARM64 now supports dotprod instructions (sdot/udot).
  * AMD64 better supports code build with -march=x86-64-v3.
    fused-multiple-add instructions (fma) are now emulated more
    accurately. And memcheck now handles __builtin_strcmp using 128/256
    bit vectors with sse4.1, avx/avx2.
  * S390X added support for NNPA (neural network processing assist)
    facility vector instructions VCNF, VCLFNH, VCFN, VCLFNL, VCRNF and
    NNPA (z16/arch14).
  * X86 recognizes new binutils-2.42 nop patterns.
- drop VEX-x86-nop-pattern.patch (upstream)
- drop armv6-support.diff (obsolete)

- 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)
