Review rev_10043a92ba214f7599c792d3f66ebed2

{
  "summary": "Reviewed `src/math/libm_math/support/feature_detect.rs`, which provides local runtime feature-detection helpers, bit-flag caching, and macros for one-time function selection. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/math/mod.rs`, which is a Rust module wiring `libm` math intrinsics into `full_availability` and `partial_availability` exports under platform-specific `cfg` gates. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/math/libm_math/atan.rs`, which is a standard `f64` arctangent implementation with coefficient tables, range reduction, and unit tests. I checked for install hooks, network or exfiltration behavior, secret or environment access, dynamic code loading, obfuscation/packing, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/math/libm_math/sincosf.rs`, which is a pure Rust `sincosf` implementation for float trigonometry with range reduction and a small test module. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload behavior, and found no concrete malicious or supply-chain indicators in this file.\n`src/float/trunc.rs` implements floating-point truncation/conversion intrinsics (`__truncdfsf2`, `__truncsfhf2`, `__trunctfdf2`, etc.) with bitwise rounding, NaN/Infinity handling, and denormalization logic. I checked for install-time hooks, network or exfiltration code, credential/secret access, dynamic code loading, obfuscation, persistence, and other hidden execution paths, and found no concrete malicious or supply-chain indicators in this file.",
