Review rev_80fb7108868b42bd8845aeb26e6d82be

{
  "summary": "Reviewed `src/math/libm_math/tanhf.rs`, which is a small `f32` hyperbolic tangent implementation using bit-level classification, `expm1f`, and a subnormal `force_eval!` path. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior and found no concrete malicious or supply-chain indicators.\nReviewed a small Hexagon assembly implementation of `__hexagon_umodsi3` plus the `__qdsp_umodsi3` alias. It only performs integer modulo arithmetic via register operations and control flow; I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain abuse.\nReviewed `src/math/libm_math/ceil.rs`, which is a small floating-point ceil wrapper module for f16/f32/f64/f128 and dispatches to generic or architecture-selected implementations. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behaviors.\nReviewed `src/math/libm_math/floor.rs`, which is a small set of `floor` wrappers for f16/f32/f64/f128 that forward to `super::generic::floor` with architecture selection macros. I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other hidden payload execution in this file.\nReviewed `src/math/libm_math/modff.rs`, a small pure-Rust `modff` implementation that splits an `f32` into fractional and integral parts using bit operations and NaN/sign handling. I found no concrete supply-chain or malicious indicators in this file: no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior.",
