Function documentation

static void ShaderCompiler::ConstFolder::ComputeFolds(const SmallVectorImpl<FoldInputLine>& lines, SmallVectorImpl<FoldEdit>& edits)

Parses the token stream of lines and appends one FoldEdit per maximal multi-token literal-only subexpression that collapses to a single literal. Edits are sorted by (Index, Begin), never overlap and never span lines; the caller applies them back to front.
