CISB-Bench LLVM-O2: Assembly Transpilation Benchmark

Overview

This dataset is derived from the Compiler-Introduced Security Bugs (CISB) benchmark, compiled with LLVM/Clang-17 at -O2 optimization level. It supports bidirectional assembly transpilation (x86-64 ↔ AArch64) and is designed for evaluating transpilation models on security-critical code.

Dataset Structure

Column	Description
`task_name`	Full task identifier including flag (e.g., `b-4-var-0-safe`, `b-4-var-0-unsafe`)
`flag`	`"safe"` or `"unsafe"` — whether the assembly preserves the security check
`source_code`	Original C source from `cisb-bench/<variant>/code.c` (shared by safe/unsafe pairs)
`x86_64`	x86-64 assembly (`code.s` from `.build_x86/`)
`aarch64_linux`	AArch64 assembly (`code.s` from `.build_arm_linux/`)
`test_harness`	C test harness (`test.c`) for correctness verification

Statistics

Total records: 72
Safe records: 36
Unsafe records: 36

Transpilation Directions

This dataset supports both directions:

x86 → ARM: Use x86_64 as input, aarch64_linux as target
ARM → x86: Use aarch64_linux as input, x86_64 as target

Security Oracle

The test harness returns exit codes:

0 → SAFE (security check preserved)
1 → UNSAFE (security check eliminated)
2 → HARNESS_ERROR (transpilation error)
>128 → CRASH

Usage

from datasets import load_dataset

ds = load_dataset("Akirayasha/cisb-bench-llvm-O2", split="test")

# Filter by flag
safe = ds.filter(lambda x: x["flag"] == "safe")
unsafe = ds.filter(lambda x: x["flag"] == "unsafe")

# x86 -> ARM transpilation
record = ds[0]
x86_input = record["x86_64"]
arm_target = record["aarch64_linux"]

# ARM -> x86 transpilation
arm_input = record["aarch64_linux"]
x86_target = record["x86_64"]
