Review rev_362cf7682f054f07b7368944c9036234

{
  "summary": "Reviewed `src/x86_64.rs`, which defines an x86_64 stack-probing intrinsic (`___chkstk_ms`) via inline naked assembly for specific Windows/UEFI-related targets and a UEFI-only `_fltused` symbol. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nReviewed the Hexagon assembly implementation of `__hexagon_udivdi3`, which is a straightforward 64-bit unsigned division routine with a symbol alias to `__qdsp_udivdi3`. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators.\nReviewed `src/hexagon/udivmoddi4.s`, which is a small Hexagon assembly implementation of 64-bit unsigned division/remainder plus a public alias symbol. I checked the file for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload indicators, and found no concrete malicious or supply-chain indicators.\nReviewed `src/math/libm_math/sinh.rs`, which is a standalone `f64` hyperbolic-sine implementation using bit inspection plus local math helpers (`expm1`, `expo2`). I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden execution paths, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/riscv.rs`, which only defines two RISC-V software multiplication intrinsics (`__mulsi3` and conditionally `__muldi3`) using a documented shift-and-add algorithm. I checked for install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation/decoding, persistence, and other hidden control-flow or payload behavior, and found no concrete malicious or supply-chain indicators.",
