* Implement memory profiler, optimize memory usage, modify code indent * Implement memory.grow and limit heap space base offset to 1G; modify iwasm build type to Release and 64 bit by default * Add a new extension library: connection * Fix bug of reading magic number and version in big endian platform * Re-org platform APIs: move most platform APIs from iwasm to shared-lib * Enhance wasm loader to fix some security issues * Fix issue about illegal load of EXC_RETURN into PC on stm32 board * Updates that let a restricted version of the interpreter run in SGX * Enable native/app address validation and conversion for wasm app * Remove wasm_application_exectue_* APIs from wasm_export.h which makes confused * Refine binary size and fix several minor issues Optimize interpreter LOAD/STORE opcodes to decrease the binary size Fix issues when using iwasm library: _bh_log undefined, bh_memory.h not found Remove unused _stdin/_stdout/_stderr global variables resolve in libc wrapper Add macros of global heap size, stack size, heap size for Zephyr main.c Clear compile warning of wasm_application.c * Add more strict security checks for libc wrapper API's * Use one libc wrapper copy for sgx and other platforms; remove bh_printf macro for other platform header files * Enhance security of libc strcpy/sprintf wrapper function * Fix issue of call native for x86_64/arm/mips, add module inst parameter for native wrapper functions * Remove get_module_inst() and fix issue of call native * Refine wgl lib: remove module_inst parameter from widget functions; move function index check to runtime instantiate * Refine interpreter call native process, refine memory boudary check * Fix issues of invokeNative function of arm/mips/general version * Add a switch to build simple sample without gui support * Add BUILD_TARGET setting in makefile to replace cpu compiler flags in source code * Re-org shared lib header files, remove unused info; fix compile issues of vxworks * Add build target general * Remove unused files * Update license header * test push * Restore file * Sync up with internal/feature * Sync up with internal/feature * Rename build_wamr_app to build_wasm_app * Fix small issues of README * Enhance malformed wasm file checking Fix issue of print hex int and implement utf8 string check Fix wasi file read/write right issue Fix minor issue of build wasm app doc * Sync up with internal/feature * Sync up with internal/feature: fix interpreter arm issue, fix read leb issue * Sync up with internal/feature * Fix bug of config.h and rename wasi config.h to ssp_config.h * Sync up with internal/feature * Import wamr aot * update document * update document * Update document, disable WASI in 32bit * update document * remove files * update document * Update document * update document * update document * update samples * Sync up with internal repo
