Subject: [PATCH for_v23 11/16] selftests/x86/sgx: Sanitize the types for sgx_call()'s input params
Date: Mon, 7 Oct 2019 21:46:08 -0700 [thread overview]
Message-ID: <20191008044613.12350-12-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20191008044613.12350-1-sean.j.christopherson@intel.com>
Declare the unused registers for sgx_call() a 'long' instead of 'void *'
and add a comment to explain that @rdi and @rsi are declared as 'void *'
only because they're always used to pass pointers. Since the registers
are pass-through values, 'long' is the more intuitive declaration.
