Review rev_6497599640ce4f0e8c1d6af675b233cd

{
  "summary": "Reviewed `src/hexagon/sfsqrt_opt.s`, which is a Hexagon assembly implementation of `__hexagon_sqrtf` plus symbol aliases for `__qdsp_sqrtf` and `__hexagon_fast_sqrtf`/`__hexagon_fast2_sqrtf`. I checked for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation/deobfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/math/libm_math/arch/wasm32.rs`, which is a small WASM-specific math wrapper module forwarding float operations to `core::arch::wasm32` intrinsics and `abs()`. I found no concrete malicious or supply-chain indicators: no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `src/math/libm_math/tanh.rs`, a standalone floating-point `tanh(f64)` implementation that normalizes the sign bit and uses `expm1`/bit-threshold branches for numeric accuracy. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network/exfiltration calls, credential access, dynamic code loading, obfuscation/packing, or persistence behavior.\nReviewed `src/math/libm_math/rint.rs`, which only defines IEEE-style round-to-nearest-even helpers for `f16`, `f32`, `f64`, and optionally `f128`, dispatching to architecture-specific implementations or a generic rounding helper. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nReviewed `src/math/libm_math/sqrt.rs`, which is a small set of `sqrt` wrappers for f16/f32/f64/f128 that dispatch to architecture-specific implementations or the generic math path. I found no concrete indicators of install hooks, network or exfiltration, secret access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.",
