+/* Portable CPU-mode selection for libfec.
+ *
+ * The legacy SIMD path (cpu_features.s + cpu_mode_x86.c) is 32-bit x86
+ * assembly and does not assemble on x86_64 or other architectures. The
+ * viterbi27/29/615 dispatchers only compile their SSE/MMX/Altivec cases
+ * under __i386__ / __VEC__, so on every other target the PORT (generic C)
+ * path is the only one available — forcing PORT here is correct and fully
+ * portable. Replaces both cpu_mode_x86.o and cpu_features.o.
