Some issues are related with memory fragmentation, which may cause
the linear memory cannot be allocated. In WAMR, the memory managed
by the system is often trivial, but linear memory usually directly allocates
a large block and often remains unchanged for a long time. Their sensitivity
and contribution to fragmentation are different, which is suitable for
different allocation strategies. If we can control the linear memory's allocation,
do not make it from system heap, the overhead of heap management might
be avoided.
Add `mem_alloc_usage_t usage` as the first argument for user defined
malloc/realloc/free functions when `WAMR_BUILD_ALLOC_WITH_USAGE` cmake
variable is set as 1, and make passing `Alloc_For_LinearMemory` to the
argument when allocating the linear memory.
The stack profiler `aot_func#xxx` calls the wrapped function of `aot_func_internal#xxx`
by using symbol reference, but in some platform like xtensa, it’s translated into a native
long call, which needs to resolve the indirect address by relocation and breaks the XIP
feature which requires the eliminating of relocation.
The solution is to change the symbol reference into an indirect call through the lookup
table, the code will be like this:
```llvm
call_wrapped_func: ; preds = %stack_bound_check_block
%func_addr1 = getelementptr inbounds ptr, ptr %func_ptrs_ptr, i32 75
%func_tmp2 = load ptr, ptr %func_addr1, align 4
tail call void %func_tmp2(ptr %exec_env)
ret void
```
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.
esp32-s3's instruction memory and data memory can be accessed through mutual mirroring way,
so we define a new feature named as WASM_MEM_DUAL_BUS_MIRROR.
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
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
