            Bug ID: 18151
           Summary: sparc64: please expose -mno-app-regs
                    (sparc-reserve-app-registers)
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: -New Bugs

    Classification: Unclassified

In source lib/Target/Sparc/SparcRegisterInfo.cpp one sees:
static cl::opt<bool>
ReserveAppRegisters("sparc-reserve-app-registers", cl::Hidden, cl::init(false),
                    cl::desc("Reserve application registers (%g2-%g4)"));
Yet clang doesn't expose an equivalent of GCC -mno-app-regs.
