CMake Error at CMakeLists.txt:4 (cmake_minimum_required):
Compatibility with CMake < 3.5 has been removed from CMake.
Update the VERSION argument <min> value. Or, use the <min>...<max> syntax
to tell CMake that the project requires at least <min> but has been updated

Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

- Replace sys.exit with exceptions for better error handling in test assertions
- Update exception handling in compile_wast_to_wasm to catch all exceptions
- Improve error messages and logging
- Use `--ignore-whitespace` option for git apply in spec_test function
- Use raw string notation for regex patterns. *The "SyntaxWarning: invalid escape sequence" in Python The warning has been upgraded to SyntaxWarning since Python 3.12, and it is expected to become a SyntaxError in future versions.*
- Add early return for non-loadable AOT compilation to prevent unnecessary assertions
- Redirect stderr to stdout in test_case for unified output
- Update `create_tmpfiles()` to improve clarity and handling of temporary files
if using a debug building of wamrc to run spec test. there will be:
core/iwasm/compilation/aot_emit_aot_file.c:1794:13: runtime error: null pointer passed as argument 2, which is declared to never be null
- Enhance wasm mutator fuzz tests by adding export function execution and random value generation
- Use --fuel to limit loop size
- Use predefined values and enhance argument logging in execution
- Synchronize the GC spec tests to the commit from December 9. 2024.
- Revise the error messages to be consistent with the spec test cases.
- bypass gc spec test on the nuttx platform as a workaround
* Update CMakeLists.txt of fuzzing
- enable software bound-check
- enable wasi
- disable libc builtin and multiple modules
* Fix off-by-one error in result offset calculation for function calls
`module_inst->table_count = module->import_table_count + module->table_count`,
using it as an index will go through `module->import_tables` and `module->tables`,
but aot init data is only available for non-import tables.
This commit refactors the AOT loader in `aot_loader.c` to support compatible
versions of the AOT_CURRENT_VERSION constant. Previously, the loader only
accepted the exact AOT_CURRENT_VERSION value, but now it also accepts
version 3. This change ensures that the runtime can load modules AoT-compiled
with different versions of wamrc as long as they have compatible
AOT_CURRENT_VERSION values.
Related to #3880.
When checking for integer overflow, you may often write tests like p + i < p.
This works fine if p and i are unsigned integers, since any overflow in the
addition will cause the value to simply "wrap around." However, using this
pattern when p is a pointer is problematic because pointer overflow has
undefined behavior according to the C and C++ standards. If the addition
overflows and has an undefined result, the comparison will likewise be
undefined; it may produce an unintended result, or may be deleted entirely
by an optimizing compiler.
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
This PR fixes the issue reported by Oss-fuzz test (#69920).
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).
- 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
- 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
- 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 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
- 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
Enhance the statistic of wasm function execution time, or the performance
profiling feature:
- Add os_time_thread_cputime_us() to get the cputime of a thread,
and use it to calculate the execution time of a wasm function
- Support the statistic of the children execution time of a function,
and dump it in wasm_runtime_dump_perf_profiling
- Expose two APIs:
wasm_runtime_sum_wasm_exec_time
wasm_runtime_get_wasm_func_exec_time
And rename os_time_get_boot_microsecond to os_time_get_boot_us.
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.
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`
Allow to control built-in libraries for wamrc from command line options:
```bash
cmake -DWAMR_BUILD_LIBC_WASI=1/0
cmake -DWAMR_BUILD_LIBC_BUILTIN=1/0
cmake -DWAMR_BUILD_LIB_PTHREAD=1/0
cmake -DWAMR_BUILD_LIB_WASI_THREADS=1/0
```
And add some messages to show the status.
Support new a wasm_config_t, set allocation and linux_perf_support
options to it, and then pass it to wasm_engine_new_with_config to
new an engine with private configuration.
According to the description of `buildPerModuleDefaultPipeline()` and
`buildLTOPreLinkDefaultPipeline()`, it is not allowed to call them with `O0` level.
Use `buildO0DefaultPipeline` instead when the opt-level is 0.
According to the specification,
- fNxM_pmin/max returns v1 or v2 based on flt(v1,v2) result
- fNxM_min/max returns +/-NaN, +/-Inf, v1 or v2 based on more than
flt(v1,v2) result
Fixes issue #2561.
