Review Summary

Reviewed the generated x86 assembly in `aws-lc/generated-src/linux-x86/crypto/fipsmodule/bn-586.S`, which implements big-number arithmetic helpers (`bn_mul_add_words`, `bn_mul_words`, `bn_sqr_words`, `bn_div_words`, `bn_add_words`, `bn_sub_words`) with CPU-feature dispatch. I found no concrete malicious or supply-chain indicators: no install hooks, no network or exfiltration paths, no credential or secret access, no dynamic code loading, no obfuscation/packing, and no persistence or environment tampering.
