* initialize WASI stdio handles to invalid for better error handling
* implement os_invalid_raw_handle function for consistent invalid handle representation
LLVM 16 and later expands cttz intrinsic to a table lookup,
which involves some relocations. (unless ZBB is available,
in which case the native instructions are preferred over
the table-based lowering.)
cf. https://reviews.llvm.org/D128911
the corresponding LLVM intrinsics' return types are same as
their first argument. eg. i64 for llvm.cttz.i64.
cf. https://llvm.org/docs/LangRef.html#llvm-cttz-intrinsic
this commit changes the return types of our versions of the
intrinsics to match llvm versions as our aot compiler,
specifically __call_llvm_intrinsic, assumes.
strictly speaking, this is a potential AOT ABI change.
however, I suppose it isn't a problem for many of 64-bit ABIs
out there, where (lower half of) a 64-bit register is used to
return a 32-bit value anyway. (for such ABIs, this commit
would fix the upper 32-bit value of the register.)
LLVM 19 and later started to use srodata ("small read only data")
sections for RISCV. cf. https://github.com/llvm/llvm-project/pull/82214
this commit makes our aot emitter/loader deal with those sections.
an alternative would be to disable small data sections completely by
setting the "SmallDataLimit" module attribute to zero. however, i feel
this commit is more straightforward and consisitent as we are already
dealing with sdata sections.
* Fix errors on the "i386-windows-msvc" platform
* Refactor symbol name handling for AOT COFF32 binary format
* Fix preprocessor directive placement for Windows compatibility in aot_reloc_x86_32.c

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.

* Remove indirect-load for constants on Xtensa Target to improve performance
* Remove const intrinsics flags for xtensa instead of adding too much #ifdef
* Add AOT_INTRINSIC_FLAG_F32_CONST for xtensa frontend, because espressif xtensa llvm backend does not support float-point immediate for now

* Use CMAKE_INSTALL_BINDIR for wamrc installation
* Fix wamrc build failure for 32bit non-x86 targets
* Handle PIC flags by cmake in wamrc
* Use dummy AOT reloc functions when building wamrc
AOT reloc functions are used only when loading AOT WebAssembly modules
on target, not during AOT compilation. Original code led to build issues
when building wamrc as cross-compiler, using arm header on x86 build.
* Add option to turn off SIMD support in wamrc
`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.
Previously, the loader would check the name of a new export against all
existing exports, leading to a quadratic running time.
This change makes the loader parse the entire export section. The
exports are then sorted by name, then adjacent exports are checked for
uniqueness.
