{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/CMakeLists.txt`, a build script that assembles FIPS module sources, generates architecture-specific assembly, and invokes local build helpers for `delocate` and `inject_hash`. I found no concrete malicious or supply-chain indicators in this file: no install hooks, no network or exfiltration behavior, no credential or secret access, no hidden dynamic code loading, no obfuscation, and no persistence or environment tampering.\nReviewed the generated PowerPC64 assembly in `aws-lc/generated-src/linux-ppc64le/crypto/fipsmodule/ghashp8-ppc.S`, which implements GHASH/GCM routines (`gcm_init_p8`, `gcm_gmult_p8`, `gcm_ghash_p8`) with inline vector instructions and normal save/restore epilogues. I found no concrete indicators of malicious or supply-chain behavior in this file: there are no install hooks, network or exfiltration calls, credential access, dynamic code loading, obfuscation/deobfuscation pipelines, or persistence/tampering logic.",
