+/* uya_host.h: replaces the decomp's common.h when frontbin's C is built for a PC.
+ *
+ * Memory model: the host is a 32-bit x86 program, so pointers are 4 bytes like
+ * on the EE and every struct keeps its PS2 layout. PS2 main RAM is mapped at its
+ * real addresses (0x00100000-0x01FFFFFF), so the decomp's globals (declared
+ * extern, placed by address through abs_syms.s) and its absolute constants
+ * point at real memory. long is rewritten to long long by gen_host.py (the
+ * EE's long is 64-bit); build with -malign-double so 64-bit fields keep 8-byte
+ * alignment.
