When de-instantiating the wasm module instance, remove it from the module's
instance list before freeing func_ptrs and fast_jit_func_ptrs of the instance, to avoid
accessing these freed memory in the JIT backend compilation threads.
Enable setting running mode when executing a wasm bytecode file
- Four running modes are supported: interpreter, fast-jit, llvm-jit and multi-tier-jit
- Add APIs to set/get the default running mode of the runtime
- Add APIs to set/get the running mode of a wasm module instance
- Add running mode options for iwasm command line tool
And add size/opt level options for LLVM JIT
The definitions `enum WASMExceptionID` in the compilation of wamrc and the compilation
of Fast JIT are different, since the latter enables the Fast JIT macro while the former doesn't.
This causes that the exception ID in AOT file generated by wamrc may be different from
iwasm binary compiled with Fast JIT enabled, and may result in unexpected behavior.
Remove the macro control to resolve it.
Change an error to warning when checking wasi abi compatibility in loader, for rust case below:
#[no_mangle]
pub extern "C" fn main() {
println!("foo");
}
compile it with `cargo build --target wasm32-wasi`, a wasm file is generated with wasi apis imported
and a "void main(void)" function exported.
Other runtime e.g. wasmtime allows to load it and execute the main function with `--invoke` option.
- Split logic in several dockers
- runtime: wasi-nn-cpu and wasi-nn- Nvidia-gpu.
- compilation: wasi-nn-compile. Prepare the testing wasm and generates the TFLites.
- Implement GPU support for TFLite with Opencl.
The current implementation throws a segmentation fault when padding
files using a large range, because the writing operation overflows the
source buffer, which was a single char.
IPFS previously assumed that the offset for the seek operation was related
to the start of the file (SEEK_SET). It now correctly checks the parameter
'whence' and computes the offset for SEEK_CUR (middle of the file) and
SEEK_END (end of the file).
- Reorganize the library structure
- Use the latest version of `wasi-nn` wit (Oct 25, 2022):
0f77c48ec1/wasi-nn.wit.md
- Split logic that converts WASM structs to native structs in a separate file
- Simplify addition of new frameworks
Add more types for attr_container, e.g. uint8, uint32, uint64
Add more APIs for attr_container for int8, int16 and int32 types
Rename fields of the union 'jvalue' and refactor some files that use attr_container
This syscall doesn't need allocating stack or TLS and it's expected from the application
to do that instead. E.g. WASI-libc already does this for `pthread_create`.
Also fix some of the examples to allocate memory for stack and not use stack before
the stack pointer is set to a correct value.
Because stack grows from high address towards low address, the value
returned by malloc is the end of the stack, not top of the stack. The top
of the stack is the end of the allocated space (i.e. address returned by
malloc + cluster size).
Refer to #1790.
The original CI didn't actually run wasi test suite for x86-32 since the `TEST_ON_X86_32=true`
isn't written into $GITHUB_ENV.
And refine the error output when failed to link import global.
Add thread_wait_list_end node for thread data and cond for Windows platform
to speedup the thread join and cond wait operations: no need to traverse the
wait list to get the end node to append the wait node.
According to the [WASI thread specification](https://github.com/WebAssembly/wasi-threads/pull/16),
some thread identifiers are reserved and should not be used. In fact, only IDs between `1` and
`0x1FFFFFFF` are valid.
The thread ID allocator has been moved to a separate class to avoid polluting the
`lib_wasi_threads_wrapper` logic.
Should use import_function_count but not import_count to calculate
the func_index in handle_name_section when custom name section
feature is enabled.
And clear the compile warnings of mini loader.
Support modes:
- run a commander module only
- run a reactor module only
- run a commander module and a/multiple reactor modules together
commander propagates WASIArguments to reactors
Implement 2-level Multi-tier JIT engine: tier-up from Fast JIT to LLVM JIT to
get quick cold startup by Fast JIT and better performance by gradually
switching to LLVM JIT when the LLVM JIT functions are compiled by the
backend threads.

Allow to add watchpoints to variables for source debugging. For instance:
`breakpoint set variable var`
will pause WAMR execution when the address at var is written to.
Can also set read/write watchpoints by passing r/w flags. This will pause
execution when the address at var is read:
`watchpoint set variable -w read var`
Add two linked lists for read/write watchpoints. When the debug message
handler receives a watchpoint request, it adds/removes to one/both of these
lists. In the interpreter, when an address is read or stored to, check whether
the address is in these lists. If so, throw a sigtrap and suspend the process.
When a wasm module is duplicated instantiated with wasm_instance_new,
the function import info of the previous instantiation may be overwritten by
the later instantiation, which may cause unexpected behavior.
Store the function import info into the module instance to fix the issue.
This PR allows reusing thread ids once they are released. That is done by using
a stack data structure to keep track of the used ids.
When a thread is created, it takes an available identifier from the stack. When
the thread exits, it returns the id to the stack of available identifiers.

For now this implementation uses thread manager.
Not sure whether thread manager is needed in that case. In the future there'll be likely another syscall added (for pthread_exit) and for that we might need some kind of thread management - with that in mind, we keep thread manager for now and will refactor this later if needed.

Use sha256 to hash binary file content. If the incoming wasm binary is
cached before, wasm_module_new() simply returns the existed one.
Use -DWAMR_BUILD_WASM_CACHE=0/1 to control the feature.
OpenSSL 1.1.1 is required if the feature is enabled.
Record the store number of current thread with struct thread_local_stores
or tls thread_local_stores_num to fix the issue:
- Only call wasm_runtime_init_thread_env() in the first wasm_store_new of
current thread
- Only call wasm_runtime_destroy_thread_env() in the last wasm_store_delete
of current thread
And remove the unused store list in the engine.
Refine AOT exception check in the caller when returning from callee function,
remove the exception check instructions when hw bound check is enabled to
improve the performance: create guard page to trigger signal handler when
exception occurs.
Add an option to pass user data to the allocator functions. It is common to
do this so that the host embedder can pass a struct as user data and access
that struct from the allocator, which gives the host embedder the ability to
do things such as track allocation statistics within the allocator.
Compile with `cmake -DWASM_MEM_ALLOC_WITH_USER_DATA=1` to enable
the option, and the allocator functions provided by the host embedder should
be like below (an extra argument `data` is added):
void *malloc(void *data, uint32 size) { .. }
void *realloc(void *data, uint32 size) { .. }
void free(void *data, void *ptr) { .. }

Change main thread hangs when encounter debugger encounters error to
main thread exits when debugger encounters error
Change main thread blocks when debugger detaches to
main thread continues executing when debugger detaches, and main thread
exits normally when finishing executing
Create trap for error message when wasm_instance_new fails:
- Similar to [this PR](https://github.com/bytecodealliance/wasm-micro-runtime/pull/1526),
but create a wasm_trap_t to output the error msg instead of adding error_buf to the API.
- Trap will need to be deleted by the caller but is not a breaking change as it is only
created if trap is not NULL.
- Add error messages for all failure cases here, try to make them accurate but welcome
feedback for improvements.

Current SGX lib-rats wasm module hash is stored in a global buffer,
which may be overwritten if there are multiple wasm module loadings.
We move the module hash into the enclave module to resolve the issue.
And rename the SGX_IPFS macro/variable in Makefile and Enclave.edl to
make the code more consistent.
And refine the sgx-ra sample document.
Limit max_stack_cell_num/max_csp_num to be no larger than UINT16_MAX,
and don't check all_cell_num in interpreter again.
And refine some codes in interpreter.
The current implementation of remote attestation does not take into
account the integrity of the wasm module. The SHA256 of the wasm
module has been put into user_data to generate the quote, and more
parameters are exposed for further verification.
