- Implement TINY / STANDARD frame modes - tiny mode is only able to keep track on the IP
and func idx, STANDARD mode provides more capabilities (parameters, stack pointer etc.).
- Implement FRAME_PER_FUNCTION / FRAME_PER_CALL modes - frame per function adds
code at the beginning and at the end of each function for allocating / deallocating stack frame,
whereas in per-call mode the frame is allocated before each call. The exception is call to
the imported function, where frame-per-function mode also allocates the stack before the
`call` instruction (as it can't instrument the imported function).
At the moment TINY + FRAME_PER_FUNCTION is automatically enabled in case GC and perf
profiling are disabled and `values` call stack feature is not requested. In all the other cases
STANDARD + FRAME_PER_CALL is used.
STANDARD + FRAME_PER_FUNCTION and TINY + FRAME_PER_CALL are currently not
implemented but possible, and might be enabled in the future.

Mac on aarch64 uses posix_memmap.c os_mmap which doesn't do anything with
the flag MMAP_MAP_32BIT for that build so this condition ends up asserting unless
the mapping ends up in the first 4 gigs worth of addressable space.
Thsi PR changes to call os_mmap with MMAP_MAP_32BIT flag only when the target
is x86-64 or riscv64, and the macro __APPLE__ isn't enabled. The behavior is similar
to what the posix os_mmap does.

Make wamrc normalize "arm64" to "aarch64v8". Previously the only way to
make the "arm64" target was to not specify a target on 64 bit arm-based
mac builds. Now arm64 and aarch64v8 are treated as the same.
Make aot_loader accept "aarch64v8" on arm-based apple (as well as
accepting legacy "arm64" based aot targets).
This also removes __APPLE__ and __MACH__ from the block that defaults
size_level to 1 since it doesn't seem to be supported for aarch64:
`LLVM ERROR: Only small, tiny and large code models are allowed on AArch64`
Enable merged os_mmap for aot data sections first, and try enabling merged
os_mmap for them and aot text except on platform nuttx and esp-idf.
This fixes the issue that aarch64 AOT module fails to load on android:
https://github.com/bytecodealliance/wasm-micro-runtime/issues/2274
And also refine os_mmap related code.
Check whether the indices overflow UINT32_MAX or not for:
- import function count + function count
- import global count + global count
- import tag count + tag count

- Split the `aot_loader_resolve_function` into two functions to prevent
redundant module lookups and loads
- Access pre-associated module instances from `import_func_module_insts`,
avoiding unnecessary instance lookups and improving performance
Don't allow to load multiple native symbol sections in aot loader since
the aot compiler will create only one native symbol section.
Fix issue reported by Oss-fuzz test (#69633).
- possible integer overflow in adjust_table_max_size:
unsigned integer overflow: 2684354559 * 2 cannot be represented in type 'uint32'
- limit max memory size in wasm_runtime_malloc
- add more checks in aot loader
- adjust compilation options
Support to get `wasm_memory_type_t memory_type` from API
`wasm_runtime_get_import_type` and `wasm_runtime_get_export_type`,
and then get shared flag, initial page cout, maximum page count
from the memory_type:
```C
bool
wasm_memory_type_get_shared(const wasm_memory_type_t memory_type);
uint32_t
wasm_memory_type_get_init_page_count(const wasm_memory_type_t memory_type);
uint32_t
wasm_memory_type_get_max_page_count(const wasm_memory_type_t memory_type);
```
Add flag `LoadArgs.clone_wasm_binary` to control whether to clone the wasm/aot
binary in wasm-c-api module. If false, API `wasm_module_new_ex` won't clone the
binary, which may reduce the footprint.
Add flag `LoadArgs.wasm_binary_freeable` to control whether the wasm/aot binary
may be freed after instantiation for wamr API `wasm_runtime_load_ex`, if yes, then
for some running modes, the wasm/aot module doesn't refer to the input binary
again so developer can free it after instantiation to reduce the footprint.
And add API `wasm_module_is_underlying_binary_freeable` and
`wasm_runtime_is_underlying_binary_freeable` to check whether the input binary
can be freed after instantiation for wasm-c-api and wamr api.
And add sample to illustrate it.
Support getting global type from `wasm_runtime_get_import_type` and
`wasm_runtime_get_export_type`, and add two APIs:
```C
wasm_valkind_t
wasm_global_type_get_valkind(const wasm_global_type_t global_type);
bool
wasm_global_type_get_mutable(const wasm_global_type_t global_type);
```
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
- Add new API wasm_runtime_load_ex() in wasm_export.h
and wasm_module_new_ex in wasm_c_api.h
- Put aot_create_perf_map() into a separated file aot_perf_map.c
- In perf.map, function names include user specified module name
- Enhance the script to help flamegraph generations
Fix the warnings and issues reported:
- in Windows platform
- by CodeQL static code analyzing
- by Coverity static code analyzing
And update CodeQL script to build exception handling and memory features.
The symbols in windows 32-bit may start with '_' and can not be found
when resolving the relocations to them. This PR ignores the underscore
when handling the relocation name of AOT_FUNC_INTERNAL_PREFIX, and
redirect the relocation with name "_aot_stack_sizes" to the relocation with
name ".aot_stack_sizes" (the name of the data section created).
ps.
https://github.com/bytecodealliance/wasm-micro-runtime/issues/3216
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
```
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.
The content in custom name section is changed after loaded since the strings
are adjusted with '\0' appended, the emitted AOT file then cannot be loaded.
The PR disables changing the content for AOT compiler to resolve it.
And disable emitting custom name section for `wamrc --enable-dump-call-stack`,
instead, use `wamrc --emit-custom-sections=name` to emit it.
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.
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`
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`.

Add an extra argument `os_file_handle file` for `os_mmap` to support
mapping file from a file fd, and remove `os_get_invalid_handle` from
`posix_file.c` and `win_file.c`, instead, add it in the `platform_internal.h`
files to remove the dependency on libc-wasi.

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.
When AOT out of bound linear memory access or stack overflow occurs, the call stack of
AOT functions cannot be unwound currently, so from the exception handler, runtime
cannot jump back into the place that calls the AOT function.
We temporarily skip the current instruction and let AOT code continue to run and return
to caller as soon as possible. And use the zydis library the decode the current instruction
to get its size.
And remove using RtlAddFunctionTable to register the AOT functions since it doesn't work
currently.
esp32-s3's instruction memory and data memory can be accessed through mutual mirroring way,
so we define a new feature named as WASM_MEM_DUAL_BUS_MIRROR.
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.
Segue is an optimization technology which uses x86 segment register to store
the WebAssembly linear memory base address, so as to remove most of the cost
of SFI (Software-based Fault Isolation) base addition and free up a general
purpose register, by this way it may:
- Improve the performance of JIT/AOT
- Reduce the footprint of JIT/AOT, the JIT/AOT code generated is smaller
- Reduce the compilation time of JIT/AOT
This PR uses the x86-64 GS segment register to apply the optimization, currently
it supports linux and linux-sgx platforms on x86-64 target. By default it is disabled,
developer can use the option below to enable it for wamrc and iwasm(with LLVM
JIT enabled):
```bash
wamrc --enable-segue=[<flags>] -o output_file wasm_file
iwasm --enable-segue=[<flags>] wasm_file [args...]
```
`flags` can be:
i32.load, i64.load, f32.load, f64.load, v128.load,
i32.store, i64.store, f32.store, f64.store, v128.store
Use comma to separate them, e.g. `--enable-segue=i32.load,i64.store`,
and `--enable-segue` means all flags are added.
