现在线性内存默认是用os_mmap分配的,感觉shared heap是不是也这样好点?改成调用wasm_mmap_linear_memory?
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`
…3756) Fix the compilation error of this CI: https://github.com/bytecodealliance/wasm-micro-runtime/actions/runs/10575515238 ``` /__w/wasm-micro-runtime/wasm-micro-runtime/bloaty/third_party/abseil-cpp/absl/debugging/failure_signal_handler.cc:139:32: error: no matching function for call to 'max(long int, int)' 139 | size_t stack_size = (std::max(SIGSTKSZ, 65536) + page_mask) & ~page_mask; | ~~~~~~~~^~~~~~~~~~~~~~~~~ ```
…rge_aot_data_text Merge branch dev/merge_aot_data_text into main to keep the commit history.
…ck is enabled (bytecodealliance#3754) In the AOT compiler, allow the user to control stack boundary check when the boundary check is enabled (e.g. `wamrc --bounds-checks=1`). Now the code logic is: 1. When `--stack-bounds-checks` is not set, it will be the same value as `--bounds-checks`. 2. When `--stack-bounds-checks` is set, it will be the option value no matter what the status of `--bounds-checks` is.
…64 or riscv64 (bytecodealliance#3755) 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.
The specific commit has been deleted, I am pointing to the same commit in the main branch though.
- Only retry on EAGAIN, ENOMEM or EINTR. - On EINTR, don't count it against the retry budget, just keep retrying. EINTR can happen in bursts. - Log the errno on failure, and don't conditionalize that logging on BH_ENABLE_TRACE_MMAP. In other parts of the code, error logging is not conditional on that define, while turning on that tracing define makes things overly verbose.

- 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. ps. bytecodealliance#3758
