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.
Allow to invoke the quick call entry wasm_runtime_quick_invoke_c_api_import to
call the wasm-c-api import functions to speedup the calling process, which reduces
the data copying.
Use `wamrc --invoke-c-api-import` to generate the optimized AOT code, and set
`jit_options->quick_invoke_c_api_import` true in wasm_engine_new when LLVM JIT
is enabled.
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`.

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.
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
Allow to use `cmake -DWAMR_CONFIGURABLE_BOUNDS_CHECKS=1` to
build iwasm, and then run `iwasm --disable-bounds-checks` to disable the
memory access boundary checks.
And add two APIs:
`wasm_runtime_set_bounds_checks` and `wasm_runtime_is_bounds_checks_enabled`
## 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.
The runtime instance memory layout changed when GC was enabled. With this patch
the GC is enabled for wamrc, but it keeps the compatibility with iwasm no matter GC
is enabled for it or not.
It may waste some memory for iwasm without GC support since the GC relative fields
for the table instance are always here, let's optimization it after AOT fully supports GC.
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.
The latest GC spec proposal has changed a lot since we implemented the feature,
refactor it based on the main branch. Part of the spec cases were tested.
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.
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.
- 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
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.
Refer to:
https://github.com/bytecodealliance/wasm-micro-runtime/issues/1302
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.
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.
