Implement multi-memory for classic-interpreter. Support core spec (and bulk memory) opcodes now,
and will support atomic opcodes, and add multi-memory export APIs in the future.
PS: Multi-memory spec test patched a lot for linking test to adapt for multi-module implementation.
The wasm loader is failing when multi-module support is on and the dependent
modules are not found; this enforces the AOT compiler integrations to prepare
dependent modules while it isn't necessary.
This PR allows allows missing imports in wasm loader and report error in wasm
instantiation instead, which enables the integrated AOT compiler to work as if
the multi-module support isn't turned on.
Add WASI support for esp-idf platform:
1. add Kconfig and cmake scripts
2. add API "openat" when using littlefs
3. add clock/rwlock/file/socket OS adapter
Some issues are related with memory fragmentation, which may cause
the linear memory cannot be allocated. In WAMR, the memory managed
by the system is often trivial, but linear memory usually directly allocates
a large block and often remains unchanged for a long time. Their sensitivity
and contribution to fragmentation are different, which is suitable for
different allocation strategies. If we can control the linear memory's allocation,
do not make it from system heap, the overhead of heap management might
be avoided.
Add `mem_alloc_usage_t usage` as the first argument for user defined
malloc/realloc/free functions when `WAMR_BUILD_ALLOC_WITH_USAGE` cmake
variable is set as 1, and make passing `Alloc_For_LinearMemory` to the
argument when allocating the linear memory.
Enhance the GC subtyping checks:
- Fix issues in the type equivalence check
- Enable the recursive type subtyping check
- Add a equivalence type flag in defined types of aot file, if there is an
equivalence type before, just set it true and re-use the previous type
- Normalize the defined types for interpreter and AOT
- Enable spec test case type-equivalence.wast and type-subtyping.wast,
and enable some commented cases
- Enable set WAMR_BUILD_SANITIZER from cmake variable
Adding a new cmake flag (cache variable) `WAMR_BUILD_MEMORY64` to enable
the memory64 feature, it can only be enabled on the 64-bit platform/target and
can only use software boundary check. And when it is enabled, it can support both
i32 and i64 linear memory types. The main modifications are:
- wasm loader & mini-loader: loading and bytecode validating process
- wasm runtime: memory instantiating process
- classic-interpreter: wasm code executing process
- Support memory64 memory in related runtime APIs
- Modify main function type check when it's memory64 wasm file
- Modify `wasm_runtime_invoke_native` and `wasm_runtime_invoke_native_raw` to
handle registered native function pointer argument when memory64 is enabled
- memory64 classic-interpreter spec test in `test_wamr.sh` and in CI
Currently, it supports memory64 memory wasm file that uses core spec
(including bulk memory proposal) opcodes and threads opcodes.

Add cmake variable `-DWAMR_BUILD_AOT_INTRINSICS=1/0` to enable/disable
the aot intrinsic functions, which are normally used by AOT XIP feature, and
can be disabled to reduce the aot runtime binary size.
And refactor the code in aot_intrinsics.h/.c.
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.
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.
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

Follow-up on #2907. The log level is needed in the host embedder to
better integrate with the embedder's logger.
Allow the developer to customize his bh_log callback with
`cmake -DWAMR_BH_LOG=<log_callback>`,
and update sample/basic to show the usage.
In linux x86-64, developer can use cmake variable to configure whether
to enable writing linear memory base address to x86 GS register or not:
- `cmake -DWAMR_DISABLE_WRITE_GS_BASE=1`: disabled it
- `cmake -DWAMR_DISABLE_WRITE_GS_BASE=0`: enabled it
- `cmake` without `-DWAMR_DISABLE_WRITE_GS_BASE=1/0`:
auto-detected by the compiler
For shared memory, the max memory size must be defined in advanced. Re-allocation
for growing memory can't be used as it might change the base address, therefore when
OS_ENABLE_HW_BOUND_CHECK is enabled the memory is mmaped, and if the flag is
disabled, the memory is allocated. This change introduces a flag that allows users to use
mmap for reserving memory address space even if the OS_ENABLE_HW_BOUND_CHECK
is disabled.
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.
On macOS, by default, the first 4GB is occupied by the pagezero.
While it can be controlled with link time options, as we are
an library, we usually don't have a control on how to link an
executable.
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`
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.
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
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.

- 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
Allow to use `cmake -DWAMR_CONFIGURABLE_BOUNDS_CHECKS=1` to
build iwasm, and then run `iwasm --disable-bounds-checks` to disable the
memory access boundary checks.
And add two APIs:
`wasm_runtime_set_bounds_checks` and `wasm_runtime_is_bounds_checks_enabled`
Major changes:
- Public headers inside `wasi-nn/include`
- Put cmake files in `cmake` folder
- Make linux iwasm link with `${WASI_NN_LIBS}` so iwasm can enable wasi-nn
LLVM PGO (Profile-Guided Optimization) allows the compiler to better optimize code
for how it actually runs. This PR implements the AOT static PGO, and is tested on
Linux x86-64 and x86-32. The basic steps are:
1. Use `wamrc --enable-llvm-pgo -o <aot_file_of_pgo> <wasm_file>`
to generate an instrumented aot file.
2. Compile iwasm with `cmake -DWAMR_BUILD_STATIC_PGO=1` and run
`iwasm --gen-prof-file=<raw_profile_file> <aot_file_of_pgo>`
to generate the raw profile file.
3. Run `llvm-profdata merge -output=<profile_file> <raw_profile_file>`
to merge the raw profile file into the profile file.
4. Run `wamrc --use-prof-file=<profile_file> -o <aot_file> <wasm_file>`
to generate the optimized aot file.
5. Run the optimized aot_file: `iwasm <aot_file>`.
The test scripts are also added for each benchmark, run `test_pgo.sh` under
each benchmark's folder to test the AOT static pgo.
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.
