Use the previous resolved binary type info (obj_data->target_info.bin_type) to
check the endian and bit-width but not the raw binary info, the latter is not
suitable for the check for Win32 object file type.
And fix the symbol comparison issue in resolve_target_sym(), as in Win32, the
symbol name of a function added by LLVMAddFunction() is prefixed by '_',
which leads to invalid result returned by strcmp().
Refine some codes in wasm loader
Add -Wshadow to gcc compile flags and fix some variable shadowed issues
Fix function parameter/return types not checked issue
Fix fast-interp loader reserve_block_ret() not handle V128 return type issue
Fix mini loader load_table_segment_section() failed issue
Add detailed comments for argc argument in wasm_runtime_call_wasm()
Treat R_AARCH64_JUMP26 same as R_AARCH64_CALL26, both of their
relocation operation is S + A - P, the difference is that one is for call
(BL) instructions, the other is for jump (B) instructions.
Auto detect whether file is XIP file before loading module in posix like and
linux-sgx platforms, and if yes, mmap executable memory automatically to
run the XIP file.
Add document about XIP feature.
Enable test spec cases with XIP feature.
- move the wait_cond from exec_env to debug_instance, so the debug thread can be waken up by any threads
- process more general query message from debugger
- refine debug instance create/destroy mechanism
- avoid creating debug instance during module instantiating
- avoid blocking execution thread during creating debug instance
- update related documents
Don't throw exception when module_malloc memory failed:
- Exception will terminate the wasm app, it's not necessary since app can
check the result of dynamic allocation and do some cleanup or fallback
operation on failure instead of 'crash' directly.
- In acquire_wait_info, call hasn_map_find only when the address isn't NULL,
or there are many senseless error logs
When auxiliary stack global isn't found in wasm app, it must be unused in
the wasm app, we set it to __heap_base global and set its size to 0, so as to
shrink the linear memory to reduce the memory consumption.
The debug_instance_list is not protected by mutex, and the debug instance uses
the length of this list as its id. If several threads create debug instance at the
same time, they may get duplicated/same ids. This patch adds mutex to protect
this list.
The destroy_callback_list variable in thread_manager_destroy is not cleared.
When wamr is started as a task, after exiting and restarting, it will loop
endlessly in traverse_list.

Enable ref types feature and bulk memory feature by default for wamrc
and provide "--disable-ref-types", "--disable-bulk-memory" to disable
them.
And remove the ref_type_flag option in wasm_loader.c which is used to
control whether to enable ref types or not when ENABLE_REF_TYPES
macro is enabled in wamrc. As the wasm binary format with ref types
is compatible with the binary format before, we can remove the option.
Also update the spec test scripts.
Fix some potential pointer overflows in aot applying relocations and
several other places.
And add sanitizer compiler flags to wamrc CMakeLists.txt to detect
such issues.
Enable LLVM link time optimization for AOT and enable it by default,
and provide "wamrc --disable-llvm-lto" option to disable it.
And modify the spec test script, disable it by default when testing
spec cases.

This patch enables huge page support for posix platforms for performance
reason, if the request size to mmap is larger than 2MB, then we use madvise
to set some pages to huge page.
And add macro control to enable tracing the mmap/munmap.

Currently the string in the wasm/aot file will be duplicated and stored
into const string list/set in interpreter/aot loader, which leads to extra
unnecessary memory consumption if the file buffer can be referred to
after loading. We refine the string storage by:
- if the file buffer can be referred to after loading and it is writable, we
reuse the file buffer to store the string but not store it into the const
string set: move string backward and append '\0'
- emit string with '\0' only for XIP mode in which the AOT file is readonly
- if the file buffer cannot be referred to, e.g. in app manager, keep the
same behavior as before

Enable emitting custom name section to aot file when adding
`--enable-dump-call-stack` or `--enable-dump-call-stack` to
wamrc and there is custom name section in wasm file, which
can be generated by wasi-sdk/emcc "-g" option. So aot runtime
can also get the function name from the custom name section
instead of export section, to which developer should use
`--export-all` for wasi-sdk/emcc to generate export function
names.
Apply clang-format for C source files in folder core/app-mgr,
core/app-framework, and test-tools.
And rename folder component_test to component-test, update

The size used to apply "size = align_uint(size, 4)" may be different
when calculating total size (in get_object_data_sections_size) and
emitting actual data (in aot_emit_object_data_section_info) for the
object data section.
This patch fixes the "Error: emit object data section info failed".
Apply clang-format for core/iwasm/compilation and core/iwasm/libraries files.
Add wasm-c-api empty_imports sample to workflow test.
And enable triggering workflow when core/config.h changes.
Allow empty import array (but not NULL) for wasm-c-api wasm_instance_new,
which makes the code more robust, especially in use cases where imports
might be constructed dynamically.
And add a test case in samples/wasm-c-api/src/empty_imports.c to test it.
- fix data race issue between debug control thread and main thread
- fix possible memory leaks in breakpoints list
- fix memory uninitialized issues
- remove unused data structures
- add more checks when handling packet and args
- fix mini-loader issues
- fix config_common.cmake fast interp prompt issue
Apply clang-format for core/iwasm/include, core/iwasm/common and
core/iwasm/aot files.

Implement source debugging feature for classic interpreter and AOT:
- use `cmake -DWAMR_BUILD_DEBUG_INTERP=1` to enable interpreter debugging
- use `cmake -DWAMR_BUILD_DEBUG_AOT=1` to enable AOT debugging
See doc/source_debugging.md for more details.
Fix document issues: add ARC to supported targets, fix how to build wamrc for MacOS.
Fix spec case test script issue: the latest wabt has enabled simd by default, no need to
add "--enable-simd" option for test script.
Fix simd LLVM IR compilation issue: using index calculated by opcode to access array
element should not be out of array boundary, add bh_assert() for it.
