highReviewed `src/math/libm_math/cbrt.rs`, which implements a floating-point cube-root routine with rounding-mode handling, special-case fixes, and unit tests. I found no concrete indicators of malicious or supply-chain behavior in this file: no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, persistence, or other hidden payload execution. Reviewed `src/arm.rs`, which contains ARM AEABI intrinsic shims and memory helper wrappers implemented with `naked_asm!` plus straightforward `memcpy`/`memmove`/`memset` forwarding. I checked for install-time hooks, environment or credential access, network/exfiltration, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file. Reviewed `src/math/libm_math/erff.rs`, which is a pure `f32` implementation of `erff`/`erfcf` with polynomial approximations and bit-level edge-case handling for infinities and tiny values. 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, or persistence/tampering behavior. Reviewed `src/float/add.rs`, which implements floating-point addition helpers and ABI entry points for `f32`, `f64`, and optional `f128`. I checked for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess behavior, and found no concrete malicious or supply-chain indicators in this file. Reviewed `src/math/libm_math/tgamma.rs`, which is a self-contained f64 Gamma function implementation using Lanczos-style approximation, reflection for negative inputs, and special-case handling for infinities, zeros, and integers. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in the target file.
