Fix#3545 and update the build configuration for multi-module sample:
- pass debug to AOT-compiled modules
- support optional DUMP_CALL_STACK
- support optional GC
Consider the following wasm module:
```wast
(module
(func (export "foo")
i32.const 0x104
i32.const 0x12345678
i32.store
)
(memory 1 1)
)
```
While the address (0x104) is perfectly aligned for i32.store,
as our aot compiler uses 1-byte alignment for load/store LLVM
IR instructions, it often produces inefficient machine code,
especially for alignment-sensitive targets.
For example, the above "foo" function is compiled into the
following xtensa machine code.
```
0000002c <aot_func_internal#0>:
2c: 004136 entry a1, 32
2f: 07a182 movi a8, 0x107
32: 828a add.n a8, a2, a8
34: 291c movi.n a9, 18
36: 004892 s8i a9, a8, 0
39: 06a182 movi a8, 0x106
3c: 828a add.n a8, a2, a8
3e: ffff91 l32r a9, 3c <aot_func_internal#0+0x10> (ff91828a <aot_func_internal#0+0xff91825e>)
3e: R_XTENSA_SLOT0_OP .literal+0x8
41: 004892 s8i a9, a8, 0
44: 05a182 movi a8, 0x105
47: 828a add.n a8, a2, a8
49: ffff91 l32r a9, 48 <aot_func_internal#0+0x1c> (ffff9182 <aot_func_internal#0+0xffff9156>)
49: R_XTENSA_SLOT0_OP .literal+0xc
4c: 41a890 srli a10, a9, 8
4f: 0048a2 s8i a10, a8, 0
52: 04a182 movi a8, 0x104
55: 828a add.n a8, a2, a8
57: 004892 s8i a9, a8, 0
5a: f01d retw.n
```
Note that the each four bytes are stored separately using
one-byte-store instruction, s8i.
This commit tries to use larger alignments for load/store LLVM IR
instructions when possible. with this commit, the above example is
compiled into the following machine code, which seems more reasonable.
```
0000002c <aot_func_internal#0>:
2c: 004136 entry a1, 32
2f: ffff81 l32r a8, 2c <aot_func_internal#0> (81004136 <aot_func_internal#0+0x8100410a>)
2f: R_XTENSA_SLOT0_OP .literal+0x8
32: 416282 s32i a8, a2, 0x104
35: f01d retw.n
```
Note: this doesn't work well for --xip because aot_load_const_from_table()
hides the constness of the value. Maybe we need our own mechanism to
propagate the constness and the value.
The compilation errors were introduced by #3515 and occur in debug building
when wasm mini loader is compiled or GC is enabled.
And remove two wasm files in standalone test-running-modes case,
which will be generated by run.sh.
Probably it's better to skip the optimized out parameters.
(that is, parameters w/o locations)
However, I'm not sure how/if it can be done with the lldb api.
For now, just disable parameter processing to avoid crashes.
While band-aid fixes like this is not plausible IMO,
some people prefer to have some debug info even if it's
partial/limited/broken. This commit partially (re)enables
C++ processing. On the other hand, do not bother to process
variables because it's known incompatible with C++.
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).
In wasm_loader_pop_frame_offset, when the stack is in polymorphic state
and the stack top operand is VALUE_TYPE_ANY, if we popping I64/F64
operand, we should pop one offset but not two offsets.
The issue was reported in #3513 and #3514.
- Add declarations related to emitting AOT files into a separate header file
named `aot_emit_aot_file.h`
- Add API `aot_emit_aot_file_buf_ex` and refactor `aot_emit_aot_file_buf` to call it
- Expose some APIs in aot_export.h
- All files under *core/iwasm/libraries/wasi-nn* are compiled as shared libraries
- *wasi-nn.c* is shared between backends
- Every backend has a separated shared library
- If wasi-nn feature is enabled, iwasm will depend on shared library libiwasm.so
instead of linking static library libvmlib.a
- 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
The `os_mremap` and `os_getpagesize` were missing in the `core/shared/platform/riot`
and were preventing RIOT from compiling if using WAMR v2.x.x. This PR is adding
both functions and should allow RIOT to update WAMR version to v2.x.x.

This PR fixes compilation error when building with
`-DWAMR_BUILD_MINI_LOADER=1 -DWAMR_BUILD_JIT=1` or
`-DWAMR_BUILD_MINI_LOADER=1 -DWAMR_BUILD_MULTI_MODULE=1`,
though normally we don't use wasm mini loader when JIT or multi-module
is enabled.
This change supports building with `-DWAMR_BUILD_LIBC_WASI=0` and
`-DWAMR_BUILD_DEBUG_INTERP=1`, otherwise the os_socket_* functions
will be undefined.
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);
```
When datacount section exists, loader will check whether the data count
read from data segment section is same with the data count read from
datacount section, but the value of latter can be 0, loader should not
skip the check when the latter is 0. This fixes#3491.
And fix handle_name_section return value not checked issue and early
return true issue after handle_name_section.
And also add the failed case in #3491 to ba-issues.
Fix several issues in wasm loader:
- Parse a block's type index with leb int32 instead leb uint32
- Correct dst dynamic offset of loop block arguments for opcode br
when copying the stack operands to the arguments of loop block
- Free each frame_csp's param_frame_offsets when destroy loader ctx
- Fix compilation error in wasm_mini_loader.c
- Add test cases of failed issues
This PR fixes issue #3467 and #3468.
- Add a marco to limit the maxi allocable memory size of fuzz test to
2GB to avoid libFuzzer out-of-memory
- Check global type in load_global_import and load_global_section
Although I don't know what exactly the esp32s3 rom version of memset is,
it seems that the current code crashes only with a small "len". I guess
it changes the logic depending on the size.
Anyway, it's safer to use dbus here.
It looks like the preferred preprocessor check for Android is `__ANDROID__`
instead of `ANDROID`:
https://groups.google.com/g/android-ndk/c/cf9_f1SLXls
Change `(defined(ANDROID) && __ANDROID_API__ < 28)` to
`((defined(ANDROID) || defined(__ANDROID__)) && (__ANDROID_API__ < 28))`.
- Update spec test cases to commit bc76fd79cfe61033d7f4ad4a7e8fc4f996dc5ba8 on Apr. 3
- Update wabt binary to 1.0.34 to support newer spec cases
- Add comparison between table declared elem type and table elem segment value type
- Add a function to decide whether to execute test cases in a running mode
- Keep using interpreter in GC spec because wat2wasm in wabt can't compile if.wast w/o errors
- Re-factoring threads spec test case processing
- Since wabt 1.0.34 release isn't compatible with ubuntu 20.04, compile it from source code
- Disable CI to run aot multi-module temporarily, and will enable it in another PR
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.
