- Emit SIMD/ref-types/bulk-memory flags into AOT file only when the features
are really used in wasm file
- Remove unused tail-call flag and stringref flag
- Add memoy64 flag and dynamic-linking flag
- Change WASM_FEATURE_THREADS to WASM_FEATURE_MULTI_THREAD
The content in custom name section is changed after loaded since the strings
are adjusted with '\0' appended, the emitted AOT file then cannot be loaded.
The PR disables changing the content for AOT compiler to resolve it.
And disable emitting custom name section for `wamrc --enable-dump-call-stack`,
instead, use `wamrc --emit-custom-sections=name` to emit it.
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.
In some scenarios there may be lots of callings to AOT/JIT functions from the
host embedder, which expects good performance for the calling process, while
in the current implementation, runtime calls the wasm_runtime_invoke_native
to prepare the array of registers and stacks for the invokeNative assemble code,
and the latter then puts the elements in the array to physical registers and
native stacks and calls the AOT/JIT function, there may be many data copying
and handlings which impact the performance.
This PR registers some quick AOT/JIT entries for some simple wasm signatures,
and let runtime call the entry to directly invoke the AOT/JIT function instead of
calling wasm_runtime_invoke_native, which speedups the calling process.
We may extend the mechanism next to allow the developer to register his quick
AOT/JIT entries to speedup the calling process of invoking the AOT/JIT functions
for some specific signatures.
- Commit locals, stacks and stack pointer to aot frame only when gc is enabled
- Commit instruction pointer to aot frame when stack frame is enabled
- Refine alloc/free aot frame when gc isn't enabled: use fixed frame size
- Support dump call stack with bytecode offset
The wamrc execution errors were skipped in the runtest.py due to `sys.exit(1)`
was caught by upper try-catch sentence and ignored with ret_code 0 returned.
This PR fixed this script issue and fixed the related wamrc/GC issues found.
And refactor the original perf support
- use WAMR_BUILD_LINUX_PERF as the cmake compilation control
- use WASM_ENABLE_LINUX_PERF as the compiler macro
- use `wamrc --enable-linux-perf` to generate aot file which contains fp operations
- use `iwasm --enable-linux-perf` to create perf map for `perf record`
According to the specification:
```
When instantiating a module which is expected to run
with `wasi-threads`, the WASI host must first allocate shared memories to
satisfy the module's imports.
```
Currently, if a test from the spec is executed while having the `multi-module`
feature enabled, WAMR fails with `WASM module load failed: unknown import`.
That happens because spec tests use memory like this:
`(memory (export "memory") (import "foo" "bar") 1 1 shared)`
and WAMR tries to find a registered module named `foo`.
At the moment, there is no specific module name that can be used to identify
that the memory is imported because using WASI threads:
https://github.com/WebAssembly/wasi-threads/issues/33,
so this PR only avoids treating the submodule dependency not being found
as a failure.
A wasm module can be either a command or a reactor, so it can export
either `_start` or `_initialize`. Currently, if a command module is run,
`iwasm` still looks for `_initialize`, resulting in the warning:
`can not find an export 0 named _initialize in the module`.
Change to look for `_initialize` only if `_start` not found to resolve the issue.
- Fix op_br_table arity type check when the dest block is loop block
- Fix op_drop issue when the stack is polymorphic and it is to drop
an ANY type value in the stack
* Empty names are spec-wise valid.
* As we ignore unknown custom sections anyway, it's safe to
accept empty names here.
* Currently, the problem is not exposed on our CI because
the wabt version used there is a bit old.
The struct field size and field offset of a wasm struct may vary
in 32-bit target and 64-bit target, the aot compiler should not
use the offset calculated in wasm loader. It re-calculates them
according to the target info and whether GC is enabled.
And set the alignment of sruct.get/set when field size is 2, 4, or 8.
Fix opcode translation for br_on_null/br_on_non_null/br_on_cast/br_on_cast_fail
Fix global data size/offset calculation for 32-bit/64-bit targets
Fix issues in AOT file emitting and AOT loader, refine AOT file format
Fix invalid table element address used for table.get/table.set
Fix invalid struct field offset used for struct.get/struct.set
Fix aot stack frame commit for function call/call_indirect/call_ref
Add GC AOT/JIT to CI test
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.
When labels-as-values is enabled in a target which doesn't support
unaligned address access, 16-bit offset is used to store the relative
offset between two opcode labels. But it is a little small and the loader
may report "pre-compiled label offset out of range" error.
Emitting 32-bit data instead to resolve the issue: emit label address in
32-bit target and emit 32-bit relative offset in 64-bit target.

This PR implements the WebAssembly stringref proposal:
https://github.com/WebAssembly/stringref
It adds cmake variable `WAMR_BUILD_STRINGREF` to build the feature,
which will enable GC automatically.
The stringref contains two parts:
- `part 1`: add new ref types in WasmGC, add opcode processing in loader and interpreter
- `part 2`: add a library for string representation/encoding/decoding and so on
To reduce the code size introduced to WAMR, this PR only includes `part 1`,
`part 2` can be provided by embedder, they may use their own implementation,
e.g., Wasmnizer-ts uses JSString from QuickJS to implement stringref:
https://github.com/intel/Wasmnizer-ts/blob/main/runtime-library/stringref/stringref_qjs.c
We will submit another PR of `part 2` and make it as a sample rather than WAMR core part.

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.
`wasm_loader_push_pop_frame_offset` may pop n operands by using
`loader_ctx->stack_cell_num` to check whether the operand can be
popped or not. While `loader_ctx->stack_cell_num` is updated in the
later `wasm_loader_push_pop_frame_ref`, the check may fail if the stack
is in polymorphic state and lead to `ctx->frame_offset` underflow.
Fix issue #2577 and #2586.
