17 ; Used to exhaust all registers
19 ; A better way to do this might be:
21 ; @var = global [16 x i32] zeroinitializer
23 ; %tmp = load load volatile [16 x i32], [16 x i32]* @var
24 ; store volatile [16 x i32] %tmp, [16 x i32]* @var
26 ; Which is copied from `test/CodeGen/RISCV/reserved-regs.ll`.
27 ; But currently we have problem doing codegen for the above snippet
28 ; (https://bugs.llvm.org/show_bug.cgi?id=50377).
