* 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
Make wamrc normalize "arm64" to "aarch64v8". Previously the only way to
make the "arm64" target was to not specify a target on 64 bit arm-based
mac builds. Now arm64 and aarch64v8 are treated as the same.
Make aot_loader accept "aarch64v8" on arm-based apple (as well as
accepting legacy "arm64" based aot targets).
This also removes __APPLE__ and __MACH__ from the block that defaults
size_level to 1 since it doesn't seem to be supported for aarch64:
`LLVM ERROR: Only small, tiny and large code models are allowed on AArch64`
When AOT out of bound linear memory access or stack overflow occurs, the call stack of
AOT functions cannot be unwound currently, so from the exception handler, runtime
cannot jump back into the place that calls the AOT function.
We temporarily skip the current instruction and let AOT code continue to run and return
to caller as soon as possible. And use the zydis library the decode the current instruction
to get its size.
And remove using RtlAddFunctionTable to register the AOT functions since it doesn't work
currently.
AOT relocation to aot_func_internal#n is generated by wamrc --bounds-checks=1.
Resolve the issue by applying the relocation in the compilation stage by wamrc and
don't generate these relocations in the AOT file.
Fixes#2471.
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.
LLVM PGO (Profile-Guided Optimization) allows the compiler to better optimize code
for how it actually runs. This PR implements the AOT static PGO, and is tested on
Linux x86-64 and x86-32. The basic steps are:
1. Use `wamrc --enable-llvm-pgo -o <aot_file_of_pgo> <wasm_file>`
to generate an instrumented aot file.
2. Compile iwasm with `cmake -DWAMR_BUILD_STATIC_PGO=1` and run
`iwasm --gen-prof-file=<raw_profile_file> <aot_file_of_pgo>`
to generate the raw profile file.
3. Run `llvm-profdata merge -output=<profile_file> <raw_profile_file>`
to merge the raw profile file into the profile file.
4. Run `wamrc --use-prof-file=<profile_file> -o <aot_file> <wasm_file>`
to generate the optimized aot file.
5. Run the optimized aot_file: `iwasm <aot_file>`.
The test scripts are also added for each benchmark, run `test_pgo.sh` under
each benchmark's folder to test the AOT static pgo.
Various fixes and beautifications coordinated with @1c3t3a,
fixes 2 of the 3 all remaining issues from #892:
- enable to os_mmap executable memory
- fix os_malloc/os_realloc/os_free issues
- implement os_thread_get_stack_boundary
- add build scripts to include with esp-idf to use wamr as
an ESP-IDF component
- update sample and document
Use `PRIxxx` related macros to format the output strings so as to clear
compile warnings, e.g. PRIu32, PRId32, PRIX32, PRIX64 and so on.
And add the related macro definitions in platform_common.h if they
are not defined, as some compilers might not support them.
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.
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 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
zephyr build document.
