A call should never modify the stack pointer, but some backends are not so sure about this and never list SP in the regmask. For the purposes of LiveDebugValues we assume a call never clobbers SP. We already have a similar workaround in DbgValueHistoryCalculator (which we hopefully can retire soon). This fixes the availabilty of local ASANified variables on AArch64. rdar://problem/27757381 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@296847 91177308-0d34-0410-b5e6-96231b3b80d8
