This fixes the cosmopolitan platform.
- Switch `build_cosmocc.sh` and platform documentation to
explicitly use the x86_64 cosmocc compiler as multi-arch
cosmocc won't work here. Older version `cosmocc` just did
a x86_64 build.
- Add missing items from `platform_internal.h` to fix build.
Follow-up on #2907. The log level is needed in the host embedder to
better integrate with the embedder's logger.
Allow the developer to customize his bh_log callback with
`cmake -DWAMR_BH_LOG=<log_callback>`,
and update sample/basic to show the usage.
Possible alternatives:
* Make wasm_cluster_destroy_spawned_exec_env take two exec_env.
One for wasm execution and another to specify the target to destroy.
* Make execute functions to switch exec_env as briefly discussed in
https://github.com/bytecodealliance/wasm-micro-runtime/pull/2047
In linux x86-64, developer can use cmake variable to configure whether
to enable writing linear memory base address to x86 GS register or not:
- `cmake -DWAMR_DISABLE_WRITE_GS_BASE=1`: disabled it
- `cmake -DWAMR_DISABLE_WRITE_GS_BASE=0`: enabled it
- `cmake` without `-DWAMR_DISABLE_WRITE_GS_BASE=1/0`:
auto-detected by the compiler
When WAMR is embedded to other application, the lifecycle of the socket
might conflict with other usecases. E.g. if WAMR is deinitialized before any
other use of sockets, the application goes into the invalid state. The new
flag allows host application to take control over the socket initialization.
Check whether the arguments are NULL before calling bh_hash_map_find,
or lots of "HashMap find elem failed: map or key is NULL" warnings may
be dumped. Reported in #3053.
Though SIMD isn't supported by interpreter, when JIT is enabled,
developer may run `iwasm --interp <wasm_file>` to trigger the SIMD
opcode in interpreter, which isn't handled before this PR.
It seems that some users want to wrap rather large chunk of code
with wasm_runtime_begin_blocking_op/wasm_runtime_end_blocking_op.
If the wrapped code happens to have a call to
e.g. wasm_runtime_spawn_exec_env, WASM_SUSPEND_FLAG_BLOCKING is
inherited to the child exec_env and it may cause unexpected behaviors.
- Enable quick aot entry when hw bound check is disabled
- Remove unnecessary ret_type argument in the quick aot entries
- Declare detailed prototype of aot function to call in each quick aot entry
Since there is no so rich api in freertos like embedded system, simply set
CONFIG_HAS_CAP_ENTER to 1 to support posix file api for freertos.
Test file api in wasm app pass.
The build system assumed sizeof (void *) == 8 as a host system
running on a x86_64 architecture, x86 otherwise. However, this
assumption is invalid for most other architectures out there, such as
aarch64 or armv7l.
This PR refers to the CMAKE_HOST_SYSTEM_PROCESSOR variable
which, according to the documentation, typically refers to the output
from "uname -m" for Unix-like systems.
Enhance the statistic of wasm function execution time, or the performance
profiling feature:
- Add os_time_thread_cputime_us() to get the cputime of a thread,
and use it to calculate the execution time of a wasm function
- Support the statistic of the children execution time of a function,
and dump it in wasm_runtime_dump_perf_profiling
- Expose two APIs:
wasm_runtime_sum_wasm_exec_time
wasm_runtime_get_wasm_func_exec_time
And rename os_time_get_boot_microsecond to os_time_get_boot_us.
- Unused variable warning (when building in release mode):
```bash
wasm-micro-runtime/samples/wasi-threads/wasm-apps/no_pthread.c:44:9:
warning: variable 'thread_id' set but not used [-Wunused-but-set-variable]
int thread_id;
```
- When using the multi-module example and changing the files in `wasm-apps`,
they don't get recompiled when the sample is rebuilt. Adding `BUILD_ALWAYS`
as it's done in other samples.
For shared memory, the max memory size must be defined in advanced. Re-allocation
for growing memory can't be used as it might change the base address, therefore when
OS_ENABLE_HW_BOUND_CHECK is enabled the memory is mmaped, and if the flag is
disabled, the memory is allocated. This change introduces a flag that allows users to use
mmap for reserving memory address space even if the OS_ENABLE_HW_BOUND_CHECK
is disabled.
After PR #2922, the caller of wasm-c-api wasm_func_call should ensure
the params and results are correctly created, runtime doesn't check
their format again.
Not know how to make `__attribute__((no_sanitize_address))` take effect
on gcc in Ubuntu-20.04, just disable quick AOT entry for wasm-c-api
sample in nightly-run CI.
When the original wasm contains multiple compilation units, the current
logic uses the first one for everything. This commit tries to use a bit more
appropriate ones.
Errors were reported when initializing wasm_val_t values with WASM_I32_VAL like macros.
```
error: missing initializer for member ‘wasm_val_t::__paddings’ [-Werror=missing-field-initializers]
64 | wasm_val_t res = {WASM_INIT_VAL};
```
And rename DEPRECATED to WASM_API_DEPRECATED to avoid using defines with generic names.
Compilation error was reported when `cmake -DWAMR_BUILD_LIBC_WASI=0`
on linux-sgx platform:
```
core/shared/platform/linux-sgx/sgx_socket.c:8:10:
fatal error: libc_errno.h: No such file or directory
8 | #include "libc_errno.h"
| ^~~~~~~~~~~~~~
```
After fixing, both `cmake -DWAMR_BUILD_LIBC_WASI=1` and
`WAMR_BUILD_LIBC_WASI=0` work good.
The content in custom name section is changed after loaded since the strings
are adjusted with '\0' appended, the emitted AOT file then cannot be loaded.
The PR disables changing the content for AOT compiler to resolve it.
And disable emitting custom name section for `wamrc --enable-dump-call-stack`,
instead, use `wamrc --emit-custom-sections=name` to emit it.
