Review Summary

Reviewed `src/float/pow.rs`, which implements a small generic exponentiation helper and C ABI intrinsics (`__powisf2`, `__powidf2`, and optionally `__powitf2`) for floating-point powers. I checked for install hooks, subprocess or network access, secret harvesting, dynamic code loading, obfuscation, and persistence behavior; none are present in this file. Reviewed `src/math/libm_math/nextafter.rs`, which implements a floating-point `nextafter` routine using bit-level IEEE-754 manipulation and explicit overflow/underflow flag raising. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file. Reviewed `src/math/libm_math/nextafterf.rs`, which is a small floating-point implementation of `nextafterf` that manipulates `f32` bit patterns and uses `force_eval!` to trigger overflow/underflow semantics. I found no concrete signs of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file. Reviewed the Hexagon assembly implementation of unsigned 32-bit division and its symbol alias. It contains only arithmetic, loop control, and a return path; I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior. Reviewed `src/math/libm_math/modf.rs`, a small pure Rust implementation of `modf` that manipulates IEEE-754 bit patterns to split a `f64` into fractional and integer parts. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution; none were present.
