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> |

WAMR supports wasm-c-api in both interpreter mode and aot mode.
Before staring, we need to download and intall WABT.
$ cd /opt
$ wget https://github.com/WebAssembly/wabt/releases/download/1.0.19/wabt-1.0.19-ubuntu.tar.gz
$ tar -xzf wabt-1.0.19-ubuntu.tar.gz
$ mv wabt-1.0.19 wabt
By default, all samples are compiled and run in "interpreter" mode.
$ mkdir build
$ cd build
$ cmake ..
$ make
$ # it will build a library with c-api supporting.
$ # Also copy *.wasm from ../src/
$ # and generate executable files
$ # now, it is ok to run samples
$ ./hello
$ ...
$ ./global
$ ...
$ ./callback
$ ...
They can be compiled and run in aot mode when some compiling flags are given.
$ mkdir build
$ cd build
$ cmake -DWAMR_BUILD_INTERP=0 -DWAMR_BUILD_AOT=1 ..
$ make
$ # it will build a library with c-api supporting.
$ # Also copy *.wasm from ../src/
$ # and transform *.wasm to *.aot
$ # and generate executable files
$ # now, it is ok to run samples
$ ./hello
$ ...
$ ./global
$ ...
$ ./callback
