m ModuleDecl: The module to process.

ModuleDecl

A new module with the rewritten functions; m itself is unchanged.

설명

A shader author writes a mutable value as a plain const x = expr and then calls x.assign(...) or a compound assignment such as += on it; nothing marks x as a variable up front. This pass finds each such value in every function of m, declares a var for it just before the first statement that uses it, and rewrites every reference to that value, including the assignment targets themselves, to read and write the new var. An assignment through a member or index access (c.a, m[i]) declares the var for the base value c or m. Values that already have a name (function parameters, constants, override constants and existing var or let bindings) are left alone.
