highReviewed the Hexagon assembly implementation in `src/hexagon/memcpy_likely_aligned.s`. It is a small `memcpy` fast path with an alignment check and a fallback jump to `memcpy@PLT`; I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence. Reviewed the Hexagon assembly in `src/hexagon/sfdiv_opt.s`, which implements `__hexagon_divsf3` and aliases it to related floating-point divide symbols. I checked for install-time hooks, network or credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found no concrete malicious behavior in this file. Reviewed `src/math/libm_math/generic/mod.rs`, which is a plain Rust module barrel that declares local math submodules and re-exports their functions. 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. Reviewed `src/math/libm_math/trunc.rs`, which is a small set of floating-point truncation wrappers and a basic unit test. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators. Reviewed `src/hexagon/udivmodsi4.s`, which is a small Hexagon assembly implementation of unsigned division/modulo with a symbol alias for `__qdsp_udivmodsi4`. I found no concrete malicious or supply-chain indicators: no install hooks, no network or exfiltration code, no credential access, no dynamic code loading, no obfuscation/deobfuscation, and no persistence or environment tampering.
