Wenyong Huang a5188f5574 Add checks to avoid wasm_runtime_malloc memory with size 0 (#507) ... In some platforms, allocating memory with size 0 may return NULL but not an empty memory block, which causes runtime load, instantiate or execute wasm/aot file failed. We add checks to try to avoid allocating memory in runtime if the size is 0. And in wasm_runtime_malloc/free, output warning if allocate memory with size 0 and free memory with NULL ptr. Also fix some coding style issues, fix handle riscv32 ilp32d issue, and fix several wasm-c-api issues. Signed-off-by: Wenyong Huang <wenyong.huang@intel.com>		2021-01-28 16:16:02 +08:00
