Review rev_80edcc63441c48cbaca2ac6f4bfe60f2

{
  "summary": "Reviewed `aws-lc/crypto/x509/x_exten.c`, a small ASN.1/X509 extension type definition file that only declares the `X509_EXTENSION` and `X509_EXTENSIONS` encodings and generates the corresponding OpenSSL-style helpers. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise in this target file.\nReviewed `builder/prebuilt-nasm.bat`, a small Windows batch wrapper that parses arguments until `-o`, derives a basename from the requested output path, and copies a matching local `.obj` from `prebuilt-nasm`. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence logic.\nReviewed `aws-lc/crypto/x509/x_spki.c`, which only defines ASN.1 sequence layouts and generated constructors for `NETSCAPE_SPKAC` and `NETSCAPE_SPKI`. I found no concrete signs of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in this target file.\nReviewed `aws-lc/tests/compiler_features_tests/c11.c`, a small C compiler-compatibility test that includes `<stdlib.h>` and `<stdatomic.h>`, checks `ATOMIC_LONG_LOCK_FREE` at preprocessing time, and returns `EXIT_SUCCESS` from `main`. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this file.\nReviewed `aws-lc/tests/compiler_features_tests/stdalign_check.c`, a small compile-time test that includes standard headers, declares an aligned stack array, performs a trivial dead-store check, and exits success or failure. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.",
