  "message": "Do not emit trailing whitespace on blank lines (#9052)\n\n- In printWrap, avoid printing trailing spaces before newlines and on\nempty lines.\n- Remove whitespace indentation before closing parentheses on raw string\nliteral tool descriptions in wasm-opt and wasm-reduce.\n- In printStackIR, skip Pop pseudo-instructions before emitting\nindentation so that they do not produce empty lines with indentation.\n\nThe version of filecheck we currently use handles whitespace-only lines\nfine, but LLVM FileCheck and newer versions of Python filecheck require\nexplicit `{{^ +$}}` regex matchers for such lines. It\u0027s nicer to just\nnot emit whitespace-only lines in the first place if we want to upgrade\nour version of filecheck.",
