Valgrind currently does not support the following AUX vector entries: AT_DCACHEBSIZE, and AT_HWCAP2. By default these entries are suppressed by Valgrind. The attached patch adds the needed support so the user level programs can correctly determine that hardware level they are running on. Specifically that the ISA 2.07 for Power 8 is supported. Bugzilla 345695 This fix adds the needed support. It makes a minor change to allow the VEX settings of the host platform to be passed down so they can be checked against the HWCAP values. The files touched are: coregrind/m_initimg/initimg-linux.c coregrind/pub_core_initimg.h coregrind/m_main.c committed by Carl Love cel@us.ibm.com git-svn-id: svn://svn.valgrind.org/valgrind/trunk@15078
