-// This test is here to hit the `Rvalue::Repeat` case in `codegen_rvalue_operand`.
-// It only applies when the resulting array is a ZST, so the test is written in
-// such a way as to keep MIR optimizations from seeing that fact and removing
-// the local and statement altogether. (At the time of writing, no other codegen
-// test hit that code path, nor did a stage 2 build of the compiler.)
