      "summary": "`aws-lc/crypto/fipsmodule/bn/asm/armv4-mont.pl` is a Perl perlasm generator that emits ARMv4 and NEON Montgomery-multiplication assembly and optionally pipes the output through `arm-xlate.pl` during build time. I checked the subprocess invocation, template `eval` expansion, and the file for network/exfiltration, credential access, hidden downloads, obfuscation, or persistence behavior, and found no concrete malicious or supply-chain indicators.",
