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.
The CI might use clang-17 to build iwasm for Android platform and it may
report compilation error:

/home/runner/work/wasm-micro-runtime/wasm-micro-runtime/core/iwasm/libraries/libc-wasi/sandboxed-system-primitives/src/blocking_op.c:45:19: error: call to undeclared function 'preadv'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
ssize_t ret = preadv(fd, iov, iovcnt, offset);
^
Explicitly declare preadv and pwritev in android platform header file to resolve it.
`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.
There doesn't appear to be a clear reason not to support this behavior.
It seems it was disallowed previously as a precaution. See
67e2e57b02
for more context.
On posix-like platforms, the rest of wasi-threads tests
should pass after the recent changes including the following PRs:
#2516, #2524, #2529, #2571, #2576 and #2582.
Adapt API usage to new interfaces where applicable, including LLVM function
usage, obsoleted llvm::Optional type and removal of unavailable headers.
Know issues:
- AOT static PGO isn't enabled
- LLVM JIT may run failed due to llvm_orc_registerEHFrameSectionWrapper
isn't linked into iwasm
Return a WASI error code (rather than a host POSIX one). In addition,
there is no need to return an error in the case that the provided buffer
is too large.
Unaligned store v128 value to the AOT function argument of the pointer for
the extra return value may cause segmentation fault.
Fix the issue reported in #2556.
The WASI docs allow for fewer rights to be applied to an fd than requested but
not more. This behavior is also asserted in the rust WASI tests, so it's necessary
for those to pass as well.
This improves test consistency between typical local environments and
github runners.
This is necessary for some of latest wasi-threads tests.

Send a signal whose handler is no-op to a blocking thread to wake up
the blocking syscall with either EINTR equivalent or partial success.
Unlike the approach taken in the `dev/interrupt_block_insn` branch (that is,
signal + longjmp similarly to `OS_ENABLE_HW_BOUND_CHECK`), this PR
does not use longjmp because:
* longjmp from signal handler doesn't work on nuttx
refer to https://github.com/apache/nuttx/issues/10326
* the singal+longjmp approach may be too difficult for average programmers
who might implement host functions to deal with
See also https://github.com/bytecodealliance/wasm-micro-runtime/issues/1910
Remove thread local attribute of prev_sig_act_SIGSEGV/SIGBUS to allow using
custom signal handler from non-main thread since in a thread spawned by
embedder, embedder may be unable to call wasm_runtime_init_thread_env to
initialize them.
And fix the handling of prev_sig_act when its sa_handler is SIG_DFL, SIG_IGN,
or a user customized handler.
Add API wasm_runtime_terminate to terminate a module instance
by setting "terminated by user" exception to the module instance.
And update the product-mini of posix platforms.
Note: this doesn't work for some situations like blocking system calls.
Preserve errno because this function is often used like
the following. The caller wants to report the error from the main
operation (`lseek` in this example), not from fd_object_release.
```
off_t ret = lseek(fd_number(fo), offset, nwhence);
fd_object_release(fo);
if (ret < 0)
return convert_errno(errno);
```
This fixes a few test cases in wasi-threads testsuite like wasi_threads_return_main_block.
And also move the special handling for "wasi proc exit" to a more appropriate place.
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.
While wasi proc exit is not a real trap, what the runtime does on it is mostly same as
real traps. That is, kill the siblings threads and represent the exit/trap as the result of
the "process" to the user api. There seems no reason to distinguish it from real traps
here.
Note that:
- The target thread either doesn't care the specific exception type or ignore wasi
proc exit by themselves. (clear_wasi_proc_exit_exception)
- clear_wasi_proc_exit_exception only clears local exception.
Add simple infrastructure to add more unit tests in the future. At the moment tests
are only executed on Linux, but can be extended to other platforms if needed.
Use https://github.com/google/googletest/ as a framework.
As a part of stress-testing we want to ensure that mutex implementation is working
correctly and protecting shared resource to be allocated from other threads when
mutex is locked.
This test covers the most common situations that happen when some program uses
mutexes like locks from various threads, locks from the same thread etc.
- Update lldb patch due to swig was upgraded to 4.1 in macos
- Export LD_LIBRARY_PATH for searching libpython3.10.so when validating wamr-lldb
in Ubuntu-20.04
- Rename lldb-wasm.patch to lldb_wasm.path
