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.
- Remove notify_stale_threads_on_exception and change atomic.wait
to be interruptible by keep waiting and checking every one second,
like the implementation of poll_oneoff in libc-wasi
- Wait all other threads exit and then get wasi exit_code to avoid
getting invalid value
- Inherit suspend_flags of parent thread while creating new thread to
avoid terminated flag isn't set for new thread
- Fix wasi-threads test case update_shared_data_and_alloc_heap
- Add "Lib wasi-threads enabled" prompt for cmake
- Fix aot get exception, use aot_copy_exception instead
- 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.
- 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
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.
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.
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 macro WASM_ENABLE_WORD_ALING_READ to enable reading
1/2/4 and n bytes data from vram buffer, which requires 4-byte addr
alignment reading.
Eliminate XIP AOT relocations related to the below ones:
i32_div_u, f32_min, f32_max, f32_ceil, f32_floor, f32_trunc, f32_rint
Refactor LLVM JIT for some purposes:
- To simplify the source code of JIT compilation
- To simplify the JIT modes
- To align with LLVM latest changes
- To prepare for the Multi-tier JIT compilation, refer to #1302
The changes mainly include:
- Remove the MCJIT mode, replace it with ORC JIT eager mode
- Remove the LLVM legacy pass manager (only keep the LLVM new pass manager)
- Change the lazy mode's LLVM module/function binding:
change each function in an individual LLVM module into all functions in a single LLVM module
- Upgraded ORC JIT to ORCv2 JIT to enable lazy compilation
Refer to #1468
Refactor the layout of interpreter and AOT module instance:
- Unify the interp/AOT module instance, use the same WASMModuleInstance/
WASMMemoryInstance/WASMTableInstance data structures for both interpreter
and AOT
- Make the offset of most fields the same in module instance for both interpreter
and AOT, append memory instance structure, global data and table instances to
the end of module instance for interpreter mode (like AOT mode)
- For extra fields in WASM module instance, use WASMModuleInstanceExtra to
create a field `e` for interpreter
- Change the LLVM JIT module instance creating process, LLVM JIT uses the WASM
module and module instance same as interpreter/Fast-JIT mode. So that Fast JIT
and LLVM JIT can access the same data structures, and make it possible to
implement the Multi-tier JIT (tier-up from Fast JIT to LLVM JIT) in the future
- Unify some APIs: merge some APIs for module instance and memory instance's
related operations (only implement one copy)
Note that the AOT ABI is same, the AOT file format, AOT relocation types, how AOT
code accesses the AOT module instance and so on are kept unchanged.

Memory num_bytes_per_page was incorrectly set in memory enlarging for
shared memory, we fix it. And don't set memory_data_size again for shared
memory.

Fix two issues of building WAMR on Windows:
- The build_llvm.py script calls itself, spawning instances faster than they expire,
which makes Python3 eat up the entire RAM in a pretty short time.
- The MSVC compiler doesn't support preprocessor statements inside macro expressions.
Two places inside bh_assert() were found.
Fix multi-module issue:
don't call the sub module's function with "$sub_module_name$func_name"
Fix the aot_call_function free argv1 issue
Modify some API comments in wasm_export.h
Fix the wamrc help info
Normalize wasm types, for the two wasm types, if their parameter types
and result types are the same, we only save one copy, so as to reduce
the footprint and simplify the type comparison in opcode CALL_INDIRECT.
And fix issue in interpreter globals_instantiate, and remove used codes.
Remove some unused fields in module instance and the related codes,
which are introduced by emsdk some special mode (-DSIDE_MODULE=1),
and are not required now.
