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.)
Replace up_invalidate_dcache_all() with up_flush_dcache_all() in
os_dcache_flush() to properly flush the data cache instead of just
invalidating it. This ensures that any modified data in the cache
is written back to memory before execution.

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.
LLVM, by default, disables the use of C++'s built-in Run-Time Type Information.
This decision is primarily driven by concerns about code size and efficiency.
But '-fsanitize=vptr' not allowed with '-fno-rtti'.

while ideally a user should not need to care this kind of
optimization details, in reality i guess it's sometimes useful.
both of clang and GCC expose a similar option. (-fno-jump-tables)

for x86-64, llvm 17 and later sometimes uses "l" prefix
for data sections.
cf. 43249378da
because our aot file emitter/loader doesn't support such
sections, it ends up with load-time errors solving symbols like ".lrodata".
this commit fixes it by avoid placing data in the large data sections.

LLVM 18 and later, instcombine perfoms only one iteration.
it performs extra "verify fixpoint" operation when instcombine
is specified in certain ways, including how we do so here.
a problem is that the verification raises a fatal error when it
finds we didn't reach a fixpoint:
LLVM ERROR: Instruction Combining did not reach a fixpoint
after 1 iterations
while it should be rare, it's quite normal not to reach a fixpoint.
this commit fixes the issue by simply disabing the verification.

Raise wasi-sdk to 25 and wabt to 1.0.37. It includes
- Refactor CI workflow to install WASI-SDK and WABT from a composite action
- Use ExternalProject to bring wasm-apps for few samples. file/ wasi-threads/
- Refactor sample build and test steps in SGX compilation workflow for improved clarity and efficiency (workaround)
Add CMake support for EMSCRIPTEN and WAMRC, update module paths
There are two reasons for this optimization:
- The value of dlen can equal 0x1_0000_0000, even in wasm32 mode, because it is derived from (4G-0). This results in a truncation when it is passed to b_memmove_s(). Consequently, s1max becomes 0 and n is greater than s1max. To correct this, a longer type is required.
- The dlen is only used to check if there is enough space in b_memmove_s(). However, from a different angle, after confirming that both src+len and dst+len are within the memory range, we can be assured and there is no need for this explicit check.
* 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
