* fix(aot): reserve x18 register on macOS ARM64
Apple reserves CPU register x18 for TLS on ARM64. When generating AOT
code for aarch64 on macOS, LLVM may use x18, causing crashes when the
AOT code runs on macOS ARM64 (M1/M2/M3).
This patch:
1. Detects darwin/macho ABI and sets correct vendor string
2. Detects darwin/apple in default triple for platform detection
3. Adds +reserve-x18 to LLVM target features for aarch64 on macOS
The fix only applies when compiling on macOS ARM64 hosts, ensuring
generated AOT code is compatible with Apple's platform requirements.
* test(aot): add x18 register reservation test for macOS ARM64
Add a standalone test to verify that the +reserve-x18 LLVM flag is
correctly applied when compiling AOT for macOS ARM64.
On macOS ARM64, x18 is reserved by Apple for TLS (Thread Local Storage).
Without the +reserve-x18 flag, LLVM may generate code that uses x18,
causing random SIGSEGV crashes (~80% crash rate in testing).
The test:
- Creates a WASM module with 24 local variables to stress register allocation
- Compiles to AOT with -O3 optimization (which would use x18 without the fix)
- Runs 1000 iterations to verify no crashes occur
- Only runs on macOS ARM64 (skipped on other platforms)
Test results:
- Without fix: 82/100 crash rate
- With fix: 0/100 crash rate (1000 iterations verified)

* feat: enhance unsupported combination checks and update build configurations for JIT and SIMD
* In regression tests, use llvm-jit and fast-jit to replace multi-tier-jit + running mode. Multi-tier-jit contains both fast-jit and llvm-jit. Fast-jit doesn't support SIMD, but llvm-jit does. So, should multi-tier-jit support SIMD? My answer is NO.
- The regular form of multi-tier-jit uses fast-jit as tier1 and llvm-jit as
tier2. Therefore, if fast-jit doesn't support SIMD, the entire multi-tier
doesn't support SIMD either.
- `--fast-jit` and `--llvm-jit` of multi-tier-jit should adhere to the global
limitations of multi-tier-jit.
* Explicitly specify SIMD, MULTI_MODULE, and their unsupported running modes.
- SIMD and Ref. types are enabled by default on linux and darwin. So remove duplicate feature testing from CI
- Apply new configuration for wasm-c-api compilation commands
- Apply global warnings in warnings.cmake instead of maintaining them in
separate files.
- Enable errors during CI when building iwasm and wamrc.
- Since GCC and Clang are the default compilers on Ubuntu and macOS, enabling
`-Werror` on both platforms can be treated as checking with different
compilers.

- Add a few API (https://github.com/bytecodealliance/wasm-micro-runtime/issues/3325)
```c
wasm_runtime_detect_native_stack_overflow_size
wasm_runtime_detect_native_stack_overflow
```
- Adapt the runtime to use them
- Adapt samples/native-stack-overflow to use them
- Add a few missing overflow checks in the interpreters
- Build and run the sample on the CI
Update the `addr2line` script so that:
- line info is printed in a more convenient format, e.g.
```
0: c
at wasm-micro-runtime/test-tools/addr2line/trap.c:5:1
1: b
at wasm-micro-runtime/test-tools/addr2line/trap.c:11:12
2: a
at wasm-micro-runtime/test-tools/addr2line/trap.c:17:12
```
similar to how Rust prints stack traces when there's a panic. In an IDE, the user
can conveniently click on the printed path and be redirected to the file line.
- a new `--no-addr` argument can be provided to the script
It can be used in fast interpreter mode (that is not supported by the script otherwise)
or with older wamr versions (where the stack trace only had the function index info
and not the function address). In that case, `wasm-objdump` is used to get the function
name from the index and `llvm-dwarfdump` to obtain the location info (where the line
refers to the start of the function).
This PR adds a max_memory_pages parameter to module instantiation APIs,
to allow overriding the max memory defined in the WASM module.
Sticking to the max memory defined in the module is quite limiting when
using shared memory in production. If targeted devices have different
memory constraints, many wasm files have to be generated with different
max memory values. And device constraints may not be known in advance.
Being able to set the max memory value during module instantiation allows
to reuse the same wasm module, e.g. by retrying instantiation with different
max memory value.
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`.

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.
`wasi-sdk-20` pre-release can be used to avoid building `wasi-libc` to enable threads.
It's not possible to use `wasi-sdk-20` pre-release on Ubuntu 20.04 because of
incompatibility with the glibc version:
```bash
/opt/wasi-sdk/bin/clang: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found
(required by /opt/wasi-sdk/bin/clang)
```
Upgrade the version of related toolkits:
- upgrade llvm to 15.0
- upgrade wasi-sdk to 19.0
- upgrade emsdk to 3.1.28
- upgrade wabt to 1.0.31
- upgrade binaryen to 111
And upgrade the CI scripts, sample workload build scripts, Dockerfiles, and documents.
Add CIs to enable the release process of a new version of WAMR,
and build and publish the binary files when a version is released,
including iwasm, wamrc, lldb, vscode-extension and wamr-ide for
Ubuntu-20.04, Ubuntu-22.04 and MacOS.
And refine the CIs to test spec cases.
Refactor LLVM JIT for some purposes:
- To simplify the source code of JIT compilation
- To simplify the JIT modes
- To align with LLVM latest changes
- To prepare for the Multi-tier JIT compilation, refer to #1302
The changes mainly include:
- Remove the MCJIT mode, replace it with ORC JIT eager mode
- Remove the LLVM legacy pass manager (only keep the LLVM new pass manager)
- Change the lazy mode's LLVM module/function binding:
change each function in an individual LLVM module into all functions in a single LLVM module
- Upgraded ORC JIT to ORCv2 JIT to enable lazy compilation
Refer to #1468
This PR integrates an Intel SGX feature called Intel Protection File System Library (IPFS)
into the runtime to create, operate and delete files inside the enclave, while guaranteeing
the confidentiality and integrity of the data persisted. IPFS can be referred to here:
https://www.intel.com/content/www/us/en/developer/articles/technical/overview-of-intel-protected-file-system-library-using-software-guard-extensions.html
Introduce a cmake variable `WAMR_BUILD_SGX_IPFS`, when enabled, the files interaction
API of WASI will leverage IPFS, instead of the regular POSIX OCALLs. The implementation
has been written with light changes to sgx platform layer, so all the security aspects
WAMR relies on are conserved.
In addition to this integration, the following changes have been made:
- The CI workflow has been adapted to test the compilation of the runtime and sample
with the flag `WAMR_BUILD_SGX_IPFS` set to true
- Introduction of a new sample that demonstrates the interaction of the files (called `file`),
- Documentation of this new feature
