components: libc: fix pointer-to-integer cast warnings and address truncation

2025-02-22T19:16:00Z

[Problem Description] 1. When enabling RT_USING_MODULE=y, compilation warnings occur: dlelf.c:386:27: warning: cast from pointer to integer of different size dlelf.c:398:25: warning: cast from pointer to integer of different size dlelf.c:408:24: warning: cast from pointer to integer of different size 2. On RV64 architectures (e.g. Sophgo SG2042 with RISC-V Sv39 and 40-bit physical addressing), dlsym may fail when accessing addresses beyond 32-bit range. [Root Cause] In dlmodule_load_relocated_object() and dlmodule_symbol_find(), pointer is cast to rt_uint32_t which truncates: | rt_ubase_t rodata_addr = (rt_uint32_t)ptr; This causes: - Warnings on 64-bit systems (pointer width > 32-bit) - Actual address truncation on RV64 when physical address exceeds 32-bit [Solution] Replace rt_uint32_t with architecture-adaptive rt_ubase_t: | rt_ubase_t rodata_addr = (rt_ubase_t)ptr; The rt_ubase_t is defined in include/rttypes.h as: | #ifdef ARCH_CPU_64BIT | typedef rt_uint64_t rt_ubase_t; | #else | typedef rt_uint32_t rt_ubase_t; | #endif This ensures correct width casting for both 32/64-bit architectures.
