Update build wasm app document, add how to set buildflags for Rust
project to reduce the footprint.
Clear Windows warnings and a shadow warning in aot_emit_numberic.c
Refine the generated LLVM IRs at the beginning of each LLVM AOT/JIT function
to fasten the LLVM IR optimization:
- Only create argv_buf if there are func calls in this function
- Only create native stack bound if stack bound check is enabled
- Only create aux stack info if there is opcode set_global_aux_stack
- Only create native symbol if indirect_mode is enabled
- Only create memory info if there are memory operations
- Only create func_type_indexes if there is opcode call_indirect
A limitation of the current implementation of SGX IPFS in WAMR is that
it prevents to open files which are not in the current directory.
This restriction is lifted and can now open files in paths, similarly to the
WASI openat call, which takes into account the sandbox of the file system.
Add a new options to control the native stack hw bound check feature:
- Besides the original option `cmake -DWAMR_DISABLE_HW_BOUND_CHECK=1/0`,
add a new option `cmake -DWAMR_DISABLE_STACK_HW_BOUND_CHECK=1/0`
- When the linear memory hw bound check is disabled, the stack hw bound check
will be disabled automatically, no matter what the input option is
- When the linear memory hw bound check is enabled, the stack hw bound check
is enabled/disabled according to the value of input option
- Besides the original option `--bounds-checks=1/0`, add a new option
`--stack-bounds-checks=1/0` for wamrc

Support to get/set recv_buf_size/send_buf_size/reuse_port/reuse_addr for wasm app
Add socket APIs for esp-idf platform
Add setsockopt for linux-sgx platform
Allow to wait for a new debugger connection once the previous one
is disconnected:
- when receiving a detach command
- when the client socket is closed (for example, lldb process is killed)
Currently we initialize and destroy LLVM environment in aot_create_comp_context
and aot_destroy_comp_context, which are called in wasm_module_load/unload,
and the latter may be invoked multiple times, which leads to duplicated LLVM
initialization/destroy and may result in unexpected behaviors.
Move the LLVM init/destroy into runtime init/destroy to resolve the issue.
Allow to have multiple stores in an engine and multiple instances
in a store. Letting a wasm_function_t pass its wasm_store_t to make
it more efficient.
Add macro WASM_ENABLE_WORD_ALING_READ to enable reading
1/2/4 and n bytes data from vram buffer, which requires 4-byte addr
alignment reading.
Eliminate XIP AOT relocations related to the below ones:
i32_div_u, f32_min, f32_max, f32_ceil, f32_floor, f32_trunc, f32_rint
Change wasm-c-api default log level to output less logs by default:
- For debug mode, change log level from 5 to 4
- For release mode, change log level from 3 to 2
The host embedder may new/delete wasm-c-api engine simultaneously
in multiple threads, which requires lock for the operations. Since there
isn't one time called global init/destroy APIs provided by wasm-c-api,
we define a global lock and initialize it with thread mutex initializer if
the platform supports that, and use it to lock the operations of engine.
If the platform doesn't support thread mutex initializer, we require
developer to create the lock by himself to ensure the thread-safe of the
engine operations.
Allow to unregister (or unload) the previously registered native libs,
so that no need to restart the whole engine by using
`wasm_runtime_destroy/wasm_runtime_init`.
Use the cmake variable `WAMR_BUILD_GLOBAL_HEAP_POOL` and
`WAMR_BUILD_GLOBAL_HEAP_SIZE` to enable/disable the global heap pool
and set its size. And set the default global heap size in core/config.h and
the cmake files.
As a result, the developers who build iwasm can easily enable/disable the
global heap pool and change its size regardless of the iwasm implementation,
without manually finding and patching the right location for that value.
The general optimizations may create some intrinsic function calls
like llvm.memset, so we move indirect mode optimization after them
to remove these function calls at last.

Some offsets can be directly gotten at the compilation stage after the interp/AOT
module instance refactoring PR was merged, so as to reduce some unnecessary
load instructions and improve the Fast JIT performance:
- Access fields of wasm memory instance structure
- Access fields of wasm table instance structure
- Access the global data
Translate call_indirect opcode by calling wasm functions with Fast JIT IRs instead of
calling jit_call_indirect runtime API, so as to improve the performance.
Translate call native function process with Fast JIT IRs to validate each pointer argument
and convert it into native address, and then call the native function directly instead
of calling jit_invoke_native runtime API, so as to improve the performance.
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
With hardware boundary checking enabled, the app heap memory comes from `os_mmap()`.
Clearing the whole heap in the memory allocator causes process RSS to reach maximum
app heap size immediately and wastes lots of memory, so we had better remove the
unnecessary memory clean operations in the memory allocator.
Refactor the layout of interpreter and AOT module instance:
- Unify the interp/AOT module instance, use the same WASMModuleInstance/
WASMMemoryInstance/WASMTableInstance data structures for both interpreter
and AOT
- Make the offset of most fields the same in module instance for both interpreter
and AOT, append memory instance structure, global data and table instances to
the end of module instance for interpreter mode (like AOT mode)
- For extra fields in WASM module instance, use WASMModuleInstanceExtra to
create a field `e` for interpreter
- Change the LLVM JIT module instance creating process, LLVM JIT uses the WASM
module and module instance same as interpreter/Fast-JIT mode. So that Fast JIT
and LLVM JIT can access the same data structures, and make it possible to
implement the Multi-tier JIT (tier-up from Fast JIT to LLVM JIT) in the future
- Unify some APIs: merge some APIs for module instance and memory instance's
related operations (only implement one copy)
Note that the AOT ABI is same, the AOT file format, AOT relocation types, how AOT
code accesses the AOT module instance and so on are kept unchanged.

1. Support cross building wamrc and installing it
2. Remove PIE flag for Windows to fix compilation error when compiled by clang
3. Support linking LLVM shared libs to help build with system default or custom
LLVM installation and reduce binary size.
Initial integration of WASI-NN based on #1225:
- Implement the library core/iwasm/libraries/wasi-nn
- Support TensorFlow, CPU, F32 at the first stage
- Add cmake variable `-DWAMR_BUILD_WASI_NN`
- Add test case based on Docker image and update document
Refer to #1573
Add a couple of socket examples that can be used with WAMR:
- The `timeout_client` and `timeout_server` examples demonstrate socket
send and receive timeouts using the socket options
- The `multicast_client` and `multicast_server` examples demonstrate receiving
multicast packets in WASM
And add several macro controls for `socket_opts` example.
While compiling the file wasi_socket_ext.c with pedantic options (typically
`-Wimplicit-int-conversion` and `-Wmissing-prototypes`), some warnings are raised.
This PR addresses those warnings by adding missing static statements before
functions and explicitly casting a narrowing conversion.
And fix the error handling after calling getpeername.
The function was introduced to WASI about half a year ago after it already
existed in WAMR.
It caused problems with compiling `wasi_socket_ext.c` with the wasi-sdk
that already had this hostcall exported (wasi-sdk >= 15).
The approach we take is the following:
- we update WASI interface to be compatible with the wasi_snapshot_preview1
- compilation with `wasi_socket_ext.c` supports both wasi_sdk >= 15 and wasi_sdk < 15
(although we intend to drop support for < 15 at one point of time)
- we override `accept()` from wasi-libc - we do that because `accept()` in `wasi-libc`
doesn't support returning address (as it doesn't have `getpeername()` implemented),
so `wasi_socket_ext.c` offers more functionality right now
Resolves#1167 and #1528.

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
Fix the issue reported by #1484:
Platform ESP-IDF broken for WAMR 1.0.0 with ESP-IDF 4.4.2
Let the dummy ftruncate only work with ESP-IDF earlier than 4.4.2
Memory num_bytes_per_page was incorrectly set in memory enlarging for
shared memory, we fix it. And don't set memory_data_size again for shared
memory.

Fix two issues of building WAMR on Windows:
- The build_llvm.py script calls itself, spawning instances faster than they expire,
which makes Python3 eat up the entire RAM in a pretty short time.
- The MSVC compiler doesn't support preprocessor statements inside macro expressions.
Two places inside bh_assert() were found.
If WASM app has called pthread_detach() to detach a thread, it will be detached again
when thread exits. Attempting to detach an already detached thread may result in crash
in musl-libc. This patch fixes it.
And enable classic interpreter instead fast interpreter when llvm jit is enabled,
so as to fix the issue that llvm jit cannot handle opcode drop_64/select_64.
Remove handling opcode DROP_64/SELECT_64 in loader stage
prepare_bytecode, as they are the modified opcodes of DROP/SELECT
for optimization purpose, but not the opcodes defined by spec.
Add more checks for Fast JIT to fix the issues reported by instrument test:
- add check for the jit_value before pushing it into the stack
- add check at the end of form_and_translate_func
- add checks after each jit pass
Fix multi-module issue:
don't call the sub module's function with "$sub_module_name$func_name"
Fix the aot_call_function free argv1 issue
Modify some API comments in wasm_export.h
Fix the wamrc help info
Some configurations (eg. esp32/nuttx) have limited space for BSS,
0x20000 byte buffer is huge on embedded systems, change to
allocate the buffer dynamically.
Destroy Fast-JIT compiler after destroying the modules loaded by
multi-module feature, since the Fast JIT's code cache allocator may
be used by these modules. If the Fast JIT's code cache allocator was
destroyed, then runtime will fail to destroy these modules.
And fix the issue of destroying import module's memory instance.
Use the semantic versioning (https://semver.org) to replace the current date
versioning system, which is more general and is requested by some developers,
e.g. issue #1357.
There are three parts in the new version string:
- major. Any incompatible modification on ABIs and APIs will lead to an increment
in the value of major, which mainly includes: AOT calling conventions, AOT file
format, wasm_export.h, wasm_c_api.h, and so on.
- minor. It represents new features, including MVP/POST-MVP features, libraries,
WAMR private ones, and so one.
- patch. It represents patches.
The new version will start from 1.0.0. Update the help info and version showing for
iwasm and wamrc.
Normalize wasm types, for the two wasm types, if their parameter types
and result types are the same, we only save one copy, so as to reduce
the footprint and simplify the type comparison in opcode CALL_INDIRECT.
And fix issue in interpreter globals_instantiate, and remove used codes.
esp-idf: Make esp-idf support Libc WASI
1. Support to get WASM APP libs' DIR from upper layer
2. Add SSP support for esp-idf platform
3. Change the errno of readlinkat
Reserve one pointer size for fast-interp code_compiled_size: if the last opcode of
current function is to be dropped (e.g. OP_DROP), the peak memory usage will
be larger than the final code_compiled_size, we record the peak size to ensure
there won't be invalid memory access during the second traversing.
Remove some unused fields in module instance and the related codes,
which are introduced by emsdk some special mode (-DSIDE_MODULE=1),
and are not required now.
Add a new option WAMR_BUILD_STACK_GUARD_SIZE to set the custom
stack guard size. For most RTOS systems, we use the native stack base
address as the check boundary which may be not safe as POSIX based
systems (like Linux).
Thread data should not be destroyed when thread exits, or other thread
may not be able to join it. This PR saves the thread data into thread data
list when thread exits, sets thread status and stores the return value, so
that other thread can join it.
Also set MEM_TOP_DOWN flag for Windows VirtualAlloc to yield LLVM
JIT relocation error.
And set opt/size level to 3 for LLVM JIT for future use, currently the flags
are not used by LLVM JIT.
ASSERT_NOT_IMPLEMENTED is bh_assert, which might be no-op.
in that case, it's better to fall back to the "default" case,
which reports an error properly.
Should not clear last label's polymorphic state after current label is popped
Fix invalid func_idx check in opcode REF_FUNC
Add check when there are extra unneeded bytecodes for a wasm function
Fix dump call stack issue in interpreter introduced by hw bound check:

signal handler.
And restore the wasm stack frame to the original status after calling a
wasm function.
Lookup table for i32.const and i64.const for xtensa XIP
Lookup const offset from table for load/store opcodes for xtensa XIP
Fill capability flags for xtensa XIP
Enable lower switch pass for xtensa XIP
Import WAMR Fast JIT which is a lightweight JIT with quick startup, small footprint,
relatively good performance (~40% to ~50% of LLVM JIT) and good portability.
Platforms supported: Linux, MacOS and Linux SGX.
Arch supported: x86-64.
Since legacy binding for loop unswitch pass was removed and we can't get
it back. Implement its equivalent in `aot_llvm_extra.cpp` and use it in
`aot_compiler.c`.
Follow up to #1183.
Before resolving the module function's export in wasm_mini_loader,
"module->retain_function" need to be initialized, otherwise,

Fix build script to enable hw bound check for interpreter when
AOT is disabled, so as to enable spec cases test for interp with
hw bound check. And fix the issues found.
Implement boundary check with hardware trap for interpreter on
64-bit platforms:
- To improve the performance of interpreter and Fast JIT
- To prepare for multi-tier compilation for the feature
Linux/MacOS/Windows 64-bit are enabled.
The existing validation didn't work as expected; e.g. for address
pool: 8.8.8.8/24 the application had access to the 127.0.0.1 address (which
should not).
Fix the issue reported in #1282.
When i32/i64 rotate (rotl/rotr) with 0, the LLVM IRs translated are:
left<<0 | left>>64 and left >>0 | left<<64
The value of left >> 64 and left <<64 in LLVM are treated as poison,
which causes invalid result when executing the aot function.
Directly return left when right is 0 to fix the issue.
Sub module's auxiliary stack boundary and bottom may be different from
main module's counterpart, so when calling sub module, its aux stack info
should be gotten and set to exec_env firstly, or aux stack overflow and out
of bounds memory access exception may be thrown when calling sub
module's function.
Fix the issue reported in PR #1278.
Enhance the hw bound check reported in #1262:
When registering signal handlers for SIGSEGV & SIGBUS in boundary
check with hardware trap, preserve the previous handlers for signal
SIGSEGV and SIGBUS, and forward the signal to the preserved signal
handlers if it isn't handled by hw bound check.
Enable aot compiler and jit based on llvm-14.0 and llvm-15.0git,
replace LLVMBuildLoad/LLVMBuildInBoundsGEP/LLVMBuildCall with
LLVMBuildLoad2/LLVMBuildInBoundsGEP2/LLVMBuildCall2, and pass
them with related types, so as to meet the requirements of opaque
pointers.
And fix several compilation errors for llvm-14.0/15.0git.
Most spec cases and standalone cases are tested.
Fix the following warning introduced by the recent change.

Fix issues in PR "Refine interp/aot string storage and emitting (#820)",
which had a few issues:
- It looks a wrong byte to mark the flag
- It doesn't work for long strings (>= 0x80 in case of little endian)
This commit fixes them by maintaining a list of loaded symbols while loading

And merge the handle of unsigned/signed for %u/%d and %llu/%lld specifier
when calling snprintf.
During debugging, the debug client may request to malloc a memory space
to evaluate the user expressions. If we malloc memory from the linear memory,
it may fail when the thread is in stop status. We preserve a buffer during

memory request.
Fix the potential integer overflow of const index in const space of fast interpreter,
emit i32/i64.const opcode when the const index is larger than INT32_MAX.
And add check for the function local cell num.
Implement Berkeley Socket API for Intel SGX
- bring Berkeley socket API in Intel SGX enclaves,

Remove the `const` flag for the first argument `buf` of wasm_runtime_load as
it might be modified by runtime for footprint and performance purpose, and
update the related functions and document.
This patch allows safer (note: safer, not safe) embedding in a plugin
environment where multiple instances of the engine could be needed.
Original code initializes and tears down the full runtime during
wasm_engine_new() and wasm_engine_delete() respectively. After this
update the C API implementation keeps track of engine instances count
and inits/deinits the runtime only when needed.
This allows for example to call wasm_engine_new() twice and then call
wasm_engine_delete() once without rendering the first engine instance
invalid.
In thread_manager.c, `wasm_cluster_spawn_exec_env` creates a new module
instance but not sets wasi_ctx, so when the new exec_env calls wasm function
which uses WASI API, the WASI API functions in `libc_wasi_wrapper.c` will get
null result in calling `get_wasi_ctx` and then return `wasi_errno`.

- Support the socket API of synchronous mode, including `socket/bind/listen/accept/send/recv/close/shutdown`,
the asynchronous mode isn't supported yet.
- Support adding `--addr-pool=<pool1,pool2,..>` argument for command line to identify the valid ip address range

Fix several issues in wasm-c-api wasm_module_imports function:
1. Two of the if branches never set the module_name and name fields which are later passed as arguments to wasm_importtype_new, and eventually might cause double-free and/or use-after-free
2. Should zero module_name/name/extern_type at the start of loop iteration, and destroy their resources when failed at the end of loop iteration
2. No need to check `if (!extern_type) { continue; }`, as extern_type is converted from type and type is already checked
3. No need to wasm_importtype_vec_delete(out) when failed, as it is passed from outside and should be destroyed by outside

back to runtime to call aot_invoke_native, which calls wasm_runtime_invoke_native
and the latter calls assembly code. We did it before as there may be pointer and
string arguments to check and convert if the native function's registered signature
has character '*' and '$'.
As the built-in native function's signatures can be gotten in compilation time, we
check the pointer/string arguments and convert them into native address in AOT
code, and then invoke the native function directly, so as to improve performance.
In some Linux systems whose kernel version is smaller than 2.6.38, the macro
MADV_HUGEPAGE isn't introduced yet which causes compilation error.
Add macro control to fix the compilation error.
The littlevgl library had changed its name and domain to [LVGL](https://lvgl.io).
See https://blog.lvgl.io/2020-06-01/announcement
We change some names and links accordingly.
Also remove the cloning for tlsf library as it isn't used now.
Increase default/min native stack size when UVWASI is enabled as
UVWASI requires larger native stack size.
Increase the reserved bytes to the native thread stack boundary to
better detect the native stack overflow.
Set WASM_DISABLE_HW_BOUND_CHECK to 0 when interpreter is
enabled and AOT is disabled, as memory access boundary check
with hardware trap is only enabled in AOT/JIT mode.
Allow compilation on Windows MinGW, see build_wamr.md for more details.
Note that WASI and some other smallish details are still not supported, but
we have a starting point. See more discussion at #993
