Subject[PATCH tip/core/rcu 10/32] tools/memory-model: Update parseargs.sh for hardware verification
Date
From: "Paul E. McKenney" <paulmck@linux.ibm.com>

This commit adds a --hw argument to parseargs.sh to specify the CPU
family for a hardware verification. For example, "--hw AArch64" will
specify that a C-language litmus test is to be translated to ARMv8 and
the result verified. This will set the LKMM_HW_MAP_FILE environment
variable accordingly. If there is no --hw argument, this environment
variable will be set to the empty string.
