Functions

fuzz_oracle_init(): Void (std/fuzz/oracle.qz:24)

---

_fuzz_next_id(): Int (std/fuzz/oracle.qz:33)

---

fuzz_result_ok(): FuzzResult (std/fuzz/oracle.qz:49)

Human-readable result

---

fuzz_result_fail(): FuzzResult (std/fuzz/oracle.qz:53)

---

fuzz_check_crash(): FuzzResult (std/fuzz/oracle.qz:63)

Compile a program and check for crashes (signals or exit code > 1). Exit code 1 = normal compile error (OK). Signal = compiler bug.

---

fuzz_check_determinism(): FuzzResult (std/fuzz/oracle.qz:95)

Compile the same program twice and check that IR output is identical.

---

fuzz_check_ir_valid(): FuzzResult (std/fuzz/oracle.qz:136)

Run LLVM opt -verify on compiled IR to check for codegen bugs.

---

fuzz_check_differential(): FuzzResult (std/fuzz/oracle.qz:176)

Compile with current and alternate compiler, compare behavior.

---

fuzz_shrink(): String (std/fuzz/oracle.qz:230)

Attempt to minimize a crashing program by removing lines. Returns the smallest source that still triggers the same crash.
