Review rev_6b4987ac214340bd969d97e5856ce2a9

{
  "summary": "Reviewed `src/math/libm_math/cbrtf.rs`, which is a straightforward `f32` cube-root implementation derived from FreeBSD/Sun code and limited to bit-twiddling plus two Newton iterations. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.\nReviewed `src/hexagon/divdi3.s`, which is a small Hexagon assembly implementation of signed 64-bit division with a public alias to `__qdsp_divdi3`. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise patterns in this file.\nReviewed `src/math/libm_math/generic/fmod.rs`, which implements a generic floating-point remainder routine with bit-level exponent/mantissa handling and a small internal reduction loop. I checked for install-time hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution; none are present in this file.\nReviewed `src/hexagon/moddi3.s`, a short Hexagon assembly implementation of signed 64-bit modulo with a `__qdsp_moddi3` alias. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other hidden control-transfer behavior and found no concrete malicious or supply-chain indicators.\nReviewed `src/math/libm_math/asinf.rs`, which is a straightforward `f32` arcsine implementation using polynomial approximation and square-root reduction. I checked it for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden execution paths, and found no concrete malicious or supply-chain indicators.",
