_valgrind_ rebased to version 3.12 The _valgrind_ package has been upgraded to upstream version 3.12, which provides a number of bug fixes and enhancements over the previous version. Notable changes include: * A new option "--ignore-range-below-sp" has been added to the memcheck tool to ignore memory accesses below the stack pointer. This is a generic replacement for the now deprecated option "--workaround-gcc296-bugs=yes". * The maximum number of callers in a suppression entry generated by the "--gen-suppressions=yes" option is now equal to the value given by the "--num-callers" option. * The cost of instrumenting code blocks for the most common use case, the *memcheck* tool on the AMD64 and Intel 64 architectures, has been reduced. * Performance has been improved for debugging programs which discard a lot of instruction address ranges of 8KB or less. * Support for IBM Power 9 (ISA 3.0) architecture has been added. * Partial support for AMD FMA4 instructions has been added. * Support for cryptographic and CRC instructions on the 64-bit ARM architecture version 8 has been added.
