Review Summary

Reviewed `src/math/libm_math/rem_pio2f.rs`, which is a pure floating-point argument-reduction routine for `x rem pi/2` with a fallback to `rem_pio2_large` for large magnitudes. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this target file. This file conditionally injects a set of Hexagon assembly sources into the build via `global_asm!` when `no-asm` is disabled. I checked it for install hooks, subprocesses, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file. Reviewed `src/hexagon/divsi3.s`, a short Hexagon assembly implementation of signed integer division and an alias symbol. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload execution, and found no concrete malicious or supply-chain indicators in this file. Reviewed src/hexagon/umoddi3.s, which is a small Hexagon assembly implementation of unsigned 64-bit modulo with a symbol alias for __qdsp_umoddi3. I checked for install hooks, hidden subprocesses, network or credential access, dynamic code loading, obfuscation/deobfuscation, and persistence/tampering behavior, and found no concrete malicious or supply-chain indicators in this file. Reviewed `src/x86.rs`, which contains two conditional naked-assembly x86 stubs (`__chkstk` and `_alloca`) for Windows GNU and UEFI builds. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload execution, and found no concrete malicious or supply-chain indicators in this file.
