fnmatch() — internals

Where it lives

• Signature: src/builtins/io/fnmatch.rs
• Lowering: src/codegen/lower_inst/builtins/io.rs:4599 (lower_fnmatch)
• Function symbol: lower_fnmatch()

Lowering notes

• Lowers fnmatch(pattern, filename, flags?) through the target-aware runtime helper.

Runtime helpers

No direct __rt_* helpers captured — the lowering is inlined or routes through another builtin.
