If WASM app has called pthread_detach() to detach a thread, it will be detached again
when thread exits. Attempting to detach an already detached thread may result in crash
in musl-libc. This patch fixes it.
And enable classic interpreter instead fast interpreter when llvm jit is enabled,
so as to fix the issue that llvm jit cannot handle opcode drop_64/select_64.
Remove handling opcode DROP_64/SELECT_64 in loader stage
prepare_bytecode, as they are the modified opcodes of DROP/SELECT
for optimization purpose, but not the opcodes defined by spec.
Add more checks for Fast JIT to fix the issues reported by instrument test:
- add check for the jit_value before pushing it into the stack
- add check at the end of form_and_translate_func
- add checks after each jit pass
Fix multi-module issue:
don't call the sub module's function with "$sub_module_name$func_name"
Fix the aot_call_function free argv1 issue
Modify some API comments in wasm_export.h
Fix the wamrc help info
Some configurations (eg. esp32/nuttx) have limited space for BSS,
0x20000 byte buffer is huge on embedded systems, change to
allocate the buffer dynamically.
Destroy Fast-JIT compiler after destroying the modules loaded by
multi-module feature, since the Fast JIT's code cache allocator may
be used by these modules. If the Fast JIT's code cache allocator was
destroyed, then runtime will fail to destroy these modules.
And fix the issue of destroying import module's memory instance.
Use the semantic versioning (https://semver.org) to replace the current date
versioning system, which is more general and is requested by some developers,
e.g. issue #1357.
There are three parts in the new version string:
- major. Any incompatible modification on ABIs and APIs will lead to an increment
in the value of major, which mainly includes: AOT calling conventions, AOT file
format, wasm_export.h, wasm_c_api.h, and so on.
- minor. It represents new features, including MVP/POST-MVP features, libraries,
WAMR private ones, and so one.
- patch. It represents patches.
The new version will start from 1.0.0. Update the help info and version showing for
iwasm and wamrc.
Normalize wasm types, for the two wasm types, if their parameter types
and result types are the same, we only save one copy, so as to reduce
the footprint and simplify the type comparison in opcode CALL_INDIRECT.
And fix issue in interpreter globals_instantiate, and remove used codes.
esp-idf: Make esp-idf support Libc WASI
1. Support to get WASM APP libs' DIR from upper layer
2. Add SSP support for esp-idf platform
3. Change the errno of readlinkat
Reserve one pointer size for fast-interp code_compiled_size: if the last opcode of
current function is to be dropped (e.g. OP_DROP), the peak memory usage will
be larger than the final code_compiled_size, we record the peak size to ensure
there won't be invalid memory access during the second traversing.
Remove some unused fields in module instance and the related codes,
which are introduced by emsdk some special mode (-DSIDE_MODULE=1),
and are not required now.
Add a new option WAMR_BUILD_STACK_GUARD_SIZE to set the custom
stack guard size. For most RTOS systems, we use the native stack base
address as the check boundary which may be not safe as POSIX based
systems (like Linux).
Thread data should not be destroyed when thread exits, or other thread
may not be able to join it. This PR saves the thread data into thread data
list when thread exits, sets thread status and stores the return value, so
that other thread can join it.
Also set MEM_TOP_DOWN flag for Windows VirtualAlloc to yield LLVM
JIT relocation error.
And set opt/size level to 3 for LLVM JIT for future use, currently the flags
are not used by LLVM JIT.
