// post.sh greps output_emitted.zig.

Test Configuration

MUST_RUN LANGUAGES: zig js

Post-validation Script:

#!/bin/bash
# Pins that a consumed print.blk does not ship its comptime engines in
# the program unit. The engines already ran; @import("ast") here is the
# corpse. backend_output_emitted.zig is the compiler — it keeps them.
