- Unused variable warning (when building in release mode):
```bash
wasm-micro-runtime/samples/wasi-threads/wasm-apps/no_pthread.c:44:9:
warning: variable 'thread_id' set but not used [-Wunused-but-set-variable]
int thread_id;
```
- When using the multi-module example and changing the files in `wasm-apps`,
they don't get recompiled when the sample is rebuilt. Adding `BUILD_ALWAYS`
as it's done in other samples.
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.
This PR addresses the issue with building the sgx-ra sample when the enclave under
the path product-mini/platforms/linux-sgx/enclave-sample is built beforehand.
When the enclave is built without librats ahead, an error occurs as the following
without the changes:
```bash
...
CP libvmlib.a <= /home/haoxuan/wasm-micro-runtime/samples/sgx-ra/build/libvmlib.a
/usr/local/bin/ld: libvmlib.a(lib_rats_wrapper.c.o): in function `librats_collect_wrapper':
lib_rats_wrapper.c:(.text.librats_collect_wrapper+0x4a): undefined reference to `wasm_runtime_get_module_hash'
collect2: error: ld returned 1 exit status
```
This fixes bug #2880. Zephyr 3.2 made changes to how headers are reference (see [release notes](https://docs.zephyrproject.org/latest/releases/release-notes-3.2.html)). Work item [49578](https://github.com/zephyrproject-rtos/zephyr/issues/49578) deprecated the old headers names.
The current WAMR codebase references these old headers, thus causing compile errors with
current versions of Zephyr.
This update adds #ifdefs around the header names. With this change, compiling with Zephyr 3.2.0
and above will use the new header files. Prior versions will use the existing code.
The JSON evidence is allocated on the module instance heap, but no API
was given to dispose of this memory buffer. The sample mentions using
the function free, which behaves differently depending on the
execution context.
This fix provides a new function called librats_dispose_evidence_json,
enabling freeing the JSON evidence directly from the Wasm app.
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`.

MASM (Microsoft Macro Assembler) needs to be enabled to successfully
compile .asm files on Windows. Without enabling this language
automatically in runtime_lib.cmake, Windows cmake projects using WAMR
get hard-to-diagnose linker errors about missing symbols as the assembly
file is not compiled at all.
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.
- Fix windows wamrc link error: aot_generate_tempfile_name undefined.
- Clear windows compile warnings.
- And rename folder `samples/bh_atomic` and `samples/mem_allocator` to
`samples/bh-atomic` and `samples/mem-allocator`.
- Sync source code to b9d4073a6913891ce9cbd8965c8d506075d2a45a, which is
referred by tensorflow
- Upgrade emscripten to 3.1.44
- CMake outputs are .wasm files and .aot files
Add nightly (UTC time) checks with asan and ubsan, and also put gcc-4.8 build
to nightly run since we don't need to run it with every PR.

Update wasi-libc version to resolve the hang issue when running wasi-threads cases.
Implement custom sync primitives as a counterpart of `pthread_barrier_wait` to
attempt to replace pthread sync primitives since they seem to cause data races
when running with the thread sanitizer.
Remove the test in the sample of file interaction that tries to extend the file
at the end, because this is not supported by the specifications of fseek.
The WASI exit code is now propagated by the runtime, so the CI will
indicate when a test is failing.
`wasi-sdk-20` pre-release can be used to avoid building `wasi-libc` to enable threads.
It's not possible to use `wasi-sdk-20` pre-release on Ubuntu 20.04 because of
incompatibility with the glibc version:
```bash
/opt/wasi-sdk/bin/clang: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found
(required by /opt/wasi-sdk/bin/clang)
```

Support collecting code coverage with wamr-test-suites script by using
lcov and genhtml tools, eg.:
cd tests/wamr-test-suites
./test_wamr.sh -s spec -b -P -C
The default code coverage and html files are generated at:
tests/wamr-test-suites/workspace/wamr.lcov
tests/wamr-test-suites/workspace/wamr-lcov.zip
And update wamr-test-suites scripts to support testing GC spec cases to
avoid frequent synchronization conflicts between branch main and dev/gc.
Raising "wasi proc exit" exception, spreading it to other threads and then
clearing it in all threads may result in unexpected behavior: the sub thread
may end first, handle the "wasi proc exit" exception and clear exceptions
of other threads, including the main thread. And when main thread's
exception is cleared, it may continue to run and throw "unreachable"
exception. This also leads to some assertion failed.
Ignore exception spreading for "wasi proc exit" and don't clear exception
of other threads to resolve the issue.
And add suspend flag check after atomic wait since the atomic wait may
be notified by other thread when exception occurs.
The function has been there for long. While what it does look a bit unsafe
as it calls a function which may be not wasm-wise exported explicitly, it's
useful and widely used when implementing callback-taking APIs, including
our pthread_create's implementation.
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.
Add APIs to help prepare the imports for the wasm-c-api `wasm_instance_new`:
- wasm_importtype_is_linked
- wasm_runtime_is_import_func_linked
- wasm_runtime_is_import_global_linked
- wasm_extern_new_empty
For wasm-c-api, developer may use `wasm_module_imports` to get the import
types info, check whether an import func/global is linked with the above API,
and ignore the linking of an import func/global with `wasm_extern_new_empty`.
Sample `wasm-c-api-import` is added and document is updated.
Upgrade the version of related toolkits:
- upgrade llvm to 15.0
- upgrade wasi-sdk to 19.0
- upgrade emsdk to 3.1.28
- upgrade wabt to 1.0.31
- upgrade binaryen to 111
And upgrade the CI scripts, sample workload build scripts, Dockerfiles, and documents.
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).
