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.
With this approach we can omit using memset() for the newly allocated memory
therefore the physical pages are not being used unless touched by the program.
This also simplifies the implementation.
After #2995, AOT may stop working properly on arm MacOS:
```bash
wasm-micro-runtime/core/iwasm/common/wasm_runtime_common.c,
line 1270, WASM module load failed
AOT module load failed: mmap memory failed
```
That's because, without `#include <TargetConditionals.h>`, `TARGET_OS_OSX` is undefined,
since it's definition is in that header file.
This PR adds the initial support for WASM exception handling:
* Inside the classic interpreter only:
* Initial handling of Tags
* Initial handling of Exceptions based on W3C Exception Proposal
* Import and Export of Exceptions and Tags
* Add `cmake -DWAMR_BUILD_EXCE_HANDLING=1/0` option to enable/disable
the feature, and by default it is disabled
* Update the wamr-test-suites scripts to test the feature
* Additional CI/CD changes to validate the exception spec proposal cases

While we used a different approach for poll_oneoff [1],
the implementation works only when the poll list includes
an absolute clock event. That is, if we have a thread which is
polling on descriptors without a timeout, we fail to terminate
the thread.
This commit fixes it by applying wasm_runtime_begin_blocking_op
to poll as well.
