- Merge unused field `used_to_be_wasi_ctx` in `AOTModuleInstance` into `reserved` area
- Add field `memory_lock` in `WASMMemoryInstance` for future refactor
- Go binding: fix type error
https://github.com/bytecodealliance/wasm-micro-runtime/issues/3220
- Python binding:
type annotation uses the union operator "|", which requires Python version >=3.10
This allows to know the beginning of the wasm address space. At the moment
to achieve that, we need to apply a `hack wasm_runtime_addr_app_to_native(X)-X`
to get the beginning of WASM memory in the nativ code, but I don't see a good
reason why not to allow zero address as a parameter value for this function.
Before PR compilation failed because of two errors:
1 - Usage of CMake target_link_libraries()
Make Error at CMakeLists.txt:154 (target_link_libraries):
The keyword signature for target_link_libraries has already been used with
the target "iwasm_shared". All uses of target_link_libraries with a target
must be either all-keyword or all-plain.
The uses of the keyword signature are here:
* CMakeLists.txt:148 (target_link_libraries)
See https://stackoverflow.com/questions/47737558/uses-of-target-link-libraries-must-be-either-all-keyword-or-all-plain
Fixed by adding keyword INTERFACE
2 - Undefined symbols during linkage, fixed by adding -lwsock32.
Last bit missing from #3206: demangling of function names (useful for wasm
generated from Rust for instance) using `llvm-cxxfilt`.

Update the `addr2line` script so that:
- line info is printed in a more convenient format, e.g.
```
0: c
at wasm-micro-runtime/test-tools/addr2line/trap.c:5:1
1: b
at wasm-micro-runtime/test-tools/addr2line/trap.c:11:12
2: a
at wasm-micro-runtime/test-tools/addr2line/trap.c:17:12
```
similar to how Rust prints stack traces when there's a panic. In an IDE, the user
can conveniently click on the printed path and be redirected to the file line.
- a new `--no-addr` argument can be provided to the script
It can be used in fast interpreter mode (that is not supported by the script otherwise)
or with older wamr versions (where the stack trace only had the function index info
and not the function address). In that case, `wasm-objdump` is used to get the function
name from the index and `llvm-dwarfdump` to obtain the location info (where the line
refers to the start of the function).
Merge branch dev/rust_sdk to main.
The wamr-rust-sdk has been migrated to the standalone repo:
https://github.com/bytecodealliance/wamr-rust-sdk
So here we just update the document to add the introduction.
- Address values in call stack dump are relative to file beginning
- If running under fast-interp mode, address values are relative to
every pre-compiled function beginning, which is not compatible
with addr2line
This PR adds a max_memory_pages parameter to module instantiation APIs,
to allow overriding the max memory defined in the WASM module.
Sticking to the max memory defined in the module is quite limiting when
using shared memory in production. If targeted devices have different
memory constraints, many wasm files have to be generated with different
max memory values. And device constraints may not be known in advance.
Being able to set the max memory value during module instantiation allows
to reuse the same wasm module, e.g. by retrying instantiation with different
max memory value.
If the language is not specified, CMake will try to find C++ compiler, even
though it is not really needed in that case (as the project is only written in C).
Now that the filesystem implementation is now complete, the previous
test filters on Windows can be removed. Some of the tests only pass when
certain environment variables have been set on Windows so an extra step
has been added in the wasi test runner script to modify the test config
files before the tests begin.
The stack profiler `aot_func#xxx` calls the wrapped function of `aot_func_internal#xxx`
by using symbol reference, but in some platform like xtensa, it’s translated into a native
long call, which needs to resolve the indirect address by relocation and breaks the XIP
feature which requires the eliminating of relocation.
The solution is to change the symbol reference into an indirect call through the lookup
table, the code will be like this:
```llvm
call_wrapped_func: ; preds = %stack_bound_check_block
%func_addr1 = getelementptr inbounds ptr, ptr %func_ptrs_ptr, i32 75
%func_tmp2 = load ptr, ptr %func_addr1, align 4
tail call void %func_tmp2(ptr %exec_env)
ret void
```
Fix the errors reported in the sanitizer test of nightly run CI.
When the stack is in polymorphic state, the stack operands may be changed
after pop and push operations (e.g. stack is empty but pop op can succeed
in polymorphic, and the push op can push a new operand to stack), this may
impact the following checks to other target blocks of the br_table opcode.
Use math functions only with `CONFIG_MINIMAL_LIBC=y`.
`CONFIG_PICOLIBC=y` or `CONFIG_NEWLIB_LIBC=y` provides math functions
that are used by wasm, and compilation fails when they are selected.

- Temporarily disable the deque test for the VS Code extension, as the
Rust formatter seems to malfunction after a recent VS Code update.
- Add configuration for iwasm host managed heap size, allowing users
to flexibly `malloc` memory. This also fixes the current bug that when
default size is 0, it can't run and debug.
- Apply coding style formatting for WAMR IDE source code and add a
format check for it in CI.
- Update document and some screenshots.
When running AOT code in Zephyr on STM32H743VIT6 without
CONFIG_CACHE_MANAGEMENT=y, a hard fault occurs, which leads to
SCB_CleanDCache().
It’s better to use the functions built into Zephyr.
This PR encompasses two complementing purposes:
A documentation on verifying an Intel SGX evidence as produced by WAMR,
including a guide for verification without an Intel SGX-enabled platform.
This also contains a small addition to the RA sample to extract specific
information, such as whether the enclave is running in debug mode.
A C# sample to verify evidence on trusted premises (and without Intel SGX).
Evidence is generated on untrusted environments, using Intel SGX.
As an original design rule, the code in `core/shared/platform` should not
rely on the code in `core/share/utils`. In the current implementation,
platform layer calls function `bh_memory_remap_slow` in utils layer.
This PR adds inline function `os_mremap_slow` in platform_api_vmcore.h,
and lets os_remap call it if mremap fails. And remove bh_memutils.h/c as
as they are unused.
And resolve the compilation warning in wamrc:
```bash
core/shared/platform/common/posix/posix_memmap.c:255:16:
warning: implicit declaration of function ‘bh_memory_remap_slow’
255 | return bh_memory_remap_slow(old_addr, old_size, new_size);
```
The wasm_interp_call_func_bytecode is called for the first time with the empty
module/exec_env to generate a global_handle_table. Before that happens though,
the function checks if the module instance has bounds check enabled. Because
the module instance is null, the program crashes. This PR added an extra check to
prevent the crashes.
Implement the GC (Garbage Collection) feature for interpreter mode,
AOT mode and LLVM-JIT mode, and support most features of the latest
spec proposal, and also enable the stringref feature.
Use `cmake -DWAMR_BUILD_GC=1/0` to enable/disable the feature,
and `wamrc --enable-gc` to generate the AOT file with GC supported.
And update the AOT file version from 2 to 3 since there are many AOT
ABI breaks, including the changes of AOT file format, the changes of
AOT module/memory instance layouts, the AOT runtime APIs for the
AOT code to invoke and so on.
This increases the chance to use "short" calls.
Assumptions:
- LLVM preserves the order of functions in a module
- The wrapper function are smaller than the wrapped functions
- The target CPU has "short" PC-relative variation of call/jmp instructions
and they are preferrable over the "long" ones.
A motivation:
- To avoid some relocations for XIP, I want to use xtensa PC-relative
call instructions, which can only reach ~512KB.
Using `CHECK_BULK_MEMORY_OVERFLOW(addr + offset, n, maddr)` to do the
boundary check may encounter integer overflow in `addr + offset`, change to
use `CHECK_MEMORY_OVERFLOW(n)` instead, which converts `addr` and `offset`
to uint64 first and then add them to avoid integer overflow.
