Review rev_0125fabb1fef4f1782f033749f08c84b

{
  "summary": "Reviewed `src/hexagon/dfsqrt.s`, which is a Hexagon assembly implementation of double-precision square root and its symbol aliases. I found no concrete indicators of supply-chain compromise or malicious behavior in the target file: no install hooks, no network or exfiltration, no credential/secret access, no dynamic code loading, no obfuscation/packing, and no persistence or environment tampering.\nThis file is a Rust unit test module for 256-bit integer widening, multiplication, bitwise not, and shift behavior, including debug/release overflow cases. I checked it for install-time hooks, network or exfiltration code, credential/secret access, dynamic code loading, obfuscation, persistence, and hidden subprocess behavior, and found no concrete malicious or supply-chain indicators.\nI reviewed `LICENSE.txt`, which is standard licensing boilerplate for `compiler_builtins` covering MIT, Apache-2.0 with LLVM exception, and third-party attribution notes. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network/exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other executable payload markers.\nReviewed `src/math/libm_math/generic/fma.rs`, which implements a pure numeric fused multiply-add routine plus a small normalization helper ported from musl. I checked for install hooks, subprocess execution, network or exfiltration paths, credential access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators.",
