This PR adds the initial support for WASM exception handling:
* Inside the classic interpreter only:
* Initial handling of Tags
* Initial handling of Exceptions based on W3C Exception Proposal
* Import and Export of Exceptions and Tags
* Add `cmake -DWAMR_BUILD_EXCE_HANDLING=1/0` option to enable/disable
the feature, and by default it is disabled
* Update the wamr-test-suites scripts to test the feature
* Additional CI/CD changes to validate the exception spec proposal cases

Enhance the statistic of wasm function execution time, or the performance
profiling feature:
- Add os_time_thread_cputime_us() to get the cputime of a thread,
and use it to calculate the execution time of a wasm function
- Support the statistic of the children execution time of a function,
and dump it in wasm_runtime_dump_perf_profiling
- Expose two APIs:
wasm_runtime_sum_wasm_exec_time
wasm_runtime_get_wasm_func_exec_time
And rename os_time_get_boot_microsecond to os_time_get_boot_us.
For shared memory, the max memory size must be defined in advanced. Re-allocation
for growing memory can't be used as it might change the base address, therefore when
OS_ENABLE_HW_BOUND_CHECK is enabled the memory is mmaped, and if the flag is
disabled, the memory is allocated. This change introduces a flag that allows users to use
mmap for reserving memory address space even if the OS_ENABLE_HW_BOUND_CHECK
is disabled.
- Don't allocate the implicit/unused frame when calling the LLVM JIT function
- Don't set exec_env's thread handle and stack boundary in the recursive
calling from host, since they have been set in the first time calling
- Fix frame not freed in llvm_jit_call_func_bytecode
Change WASMMemoryInstance's field is_shared_memory's type from bool
to uint8 whose size is fixed, so as to make WASMMemoryInstance's size
and layout fixed and not break AOT ABI.
See discussion in https://github.com/bytecodealliance/wasm-micro-runtime/pull/2682.
Currently, `data.drop` instruction is implemented by directly modifying the
underlying module. It breaks use cases where you have multiple instances
sharing a single loaded module. `elem.drop` has the same problem too.
This PR fixes the issue by keeping track of which data/elem segments have
been dropped by using bitmaps for each module instances separately, and
add a sample to demonstrate the issue and make the CI run it.
Also add a missing check of dropped elements to the fast-jit `table.init`.

Add an extra argument `os_file_handle file` for `os_mmap` to support
mapping file from a file fd, and remove `os_get_invalid_handle` from
`posix_file.c` and `win_file.c`, instead, add it in the `platform_internal.h`
files to remove the dependency on libc-wasi.

- Fix potential invalid push param phis and add incoming phis to a un-existed basic block
- Fix potential invalid shift count int rotl/rotr opcodes
- Resize memory_data_size to UINT32_MAX if it is 4G when hw bound check is enabled
- Fix negative linear memory offset is used for 64-bit target it is const and larger than INT32_MAX
Split memory instance's field `uint32 ref_count` into `bool is_shared_memory`
and `uint16 ref_count`, and lock the memory only when `is_shared_memory`
flag is true, no need to acquire a lock for non-shared memory when shared
memory feature is enabled.
Avoid repeatedly initializing the shared memory data when creating the child
thread in lib-pthread or lib-wasi-threads.
Add shared memory lock when accessing some fields of the memory instance
if the memory instance is shared.
Init shared memory's memory_data_size/memory_data_end fields according to
the current page count but not max page count.
Add wasm_runtime_set_mem_bound_check_bytes, and refine the error message
when shared memory flag is found but the feature isn't enabled.
Avoid the stack traces getting mixed up together when multi-threading is enabled
by using exception_lock/unlock in dumping the call stacks.
And remove duplicated call stack dump in wasm_application.c.
Also update coding guideline CI to fix the clang-format-12 not found issue.
Support muti-module for AOT mode, currently only implement the
multi-module's function import feature for AOT, the memory/table/
global import are not implemented yet.
And update wamr-test-suites scripts, multi-module sample and some
CIs accordingly.
Introduce module instance context APIs which can set one or more contexts created
by the embedder for a wasm module instance:
```C
wasm_runtime_create_context_key
wasm_runtime_destroy_context_key
wasm_runtime_set_context
wasm_runtime_set_context_spread
wasm_runtime_get_context
```
And make libc-wasi use it and set wasi context as the first context bound to the wasm
module instance.
Also add samples.
Refer to https://github.com/bytecodealliance/wasm-micro-runtime/issues/2460.
When embedding WAMR, this PR allows to register a callback that is
invoked when memory.grow fails.
In case of memory allocation failures, some languages allow to handle
the error (e.g. by checking the return code of malloc/calloc in C), some
others (e.g. Rust) just panic.
- Inherit shared memory from the parent instance, instead of
trying to look it up by the underlying module. The old method
works correctly only when every cluster uses different module.
- Use reference count in WASMMemoryInstance/AOTMemoryInstance
to mark whether the memory is shared or not
- Retire WASMSharedMemNode
- For atomic opcode implementations in the interpreters, use
a global lock for now
- Update the internal API users
(wasi-threads, lib-pthread, wasm_runtime_spawn_thread)
Fixes https://github.com/bytecodealliance/wasm-micro-runtime/issues/1962
## Context
Currently, WAMR supports compiling iwasm with flag `WAMR_BUILD_WASI_NN`.
However, there are scenarios where the user might prefer having it as a shared library.
## Proposed Changes
Decouple wasi-nn context management by internally managing the context given
a module instance reference.
In LLVM AOT/JIT compiler, only need to check the suspend_flags when memory is
a shared memory since the shared memory must be enabled for multi-threading,
so as not to impact the performance in non-multi-threading memory mode. Also
refine the LLVM IRs to check the suspend_flags.
And fix an issue of multi-tier jit for multi-threading, the instance of the child thread
should be removed from the instance list before it is de-instantiated.
Try using existing exec_env to execute wasm app's malloc/free func and
execute post instantiation functions. Create a new exec_env only when
no existing exec_env was found.
Use pre-created exec_env for instantiation and module_malloc/free,
use the same exec_env of the current thread to avoid potential
unexpected behavior.
And remove unnecessary shared_mem_lock in wasm_module_free,
which may cause dead lock.
- Implement atomic.fence to ensure a proper memory synchronization order
- Destroy exec_env_singleton first in wasm/aot deinstantiation
- Change terminate other threads to wait for other threads in
wasm_exec_env_destroy
- Fix detach thread in thread_manager_start_routine
- Fix duplicated lock cluster->lock in wasm_cluster_cancel_thread
- Add lib-pthread and lib-wasi-threads compilation to Windows CI
- Use execute_post_instantiate_functions to call start, _initialize,
__post_instantiate, __wasm_call_ctors functions after instantiation
- Always call start function for both main instance and sub instance
- Only call _initialize and __post_instantiate for main instance
- Only call ___wasm_call_ctors for main instance and when bulk memory
is enabled and wasi import functions are not found
- When hw bound check is enabled, use the existing exec_env_tls
to call func for sub instance, and switch exec_env_tls's module inst
to current module inst to avoid checking failure and using the wrong
module inst
The start/initialize functions of wasi module are to do some initialization work
during instantiation, which should be only called one time in the instantiation
of main instance. For example, they may initialize the data in linear memory,
if the data is changed later by the main instance, and re-initialized again by
the child instance, unexpected behaviors may occur.
And clear a shadow warning in classic interpreter.
Multiple threads generated from the same module should use the same
lock to protect the atomic operations.
Before this PR, each thread used a different lock to protect atomic
operations (e.g. atomic add), making the lock ineffective.
Fix#1958.
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
