+Subject: [PATCH] Guard avx512 module with x86 target cfg
+
+The avx512.rs module contains x86_64-specific intrinsics and target
+features that are not valid on non-x86 architectures like RISC-V.

+Subject: [PATCH 2/2] Guard x86 feature detection macro in pystrref/object.rs
+
+The std::is_x86_feature_detected! macro only works on x86/x86_64
+targets. This patch wraps the feature detection and AVX-512 code path
+with cfg guards to allow compilation on non-x86 architectures.
+
+On non-x86 targets, the code will fall through to the generic
+implementation instead of attempting AVX-512 optimizations.
