This functionality was already present in the ARM toolchain script, but
this commit adds this across all toolchain scripts. Solves an issue that
cropped up where a build error wasn't being printed unless the verbose
flag was used. This should now print any existing error messages that have
been printed when the compiler output is being parsed.
Previously, when building tests with test.py, if an exception occurred, the
error message would be masked by the function 'build_tests'. This commit
handles NotSupportedExceptions and ToolExceptions, but lets all other
Exceptions propigate up to the caller function. In most cases, this is the
CLI scripts, which will print a traceback. This will allow us to better
debug the python tools if errors occur.
The callback class can now accept generalized function-objects:
class Thing {
public:
int value;
void operator()() {
printf("hi! %d\n", value);
}
};
Callback<void()> cb(Thing(2));
However, with the intention of avoiding implicit dynamic-memory
allocations, the Callback class is limited to a single word of storage.
Exceeding this size will eliminate the function-object type from the
overload set and fail to compile.
Effort was invested to make this situation very clear to the user. Here
is an example error message with noise removed:
[ERROR] ./main.cpp: In function 'int main()':
./mbed-os/hal/api/Ticker.h:101:10: note:
no known conversion for argument 1 from 'BigFunc' to 'mbed::Callback<void()>'
The real benefit of this change is the ability for users to hook into
the attributes of the Callback class. This mostly allows lifetime
management of the function-objects from third-party libraries (such as
the Event class from mbed-events).
Note: The convenient `callback` function may become ambiguous if
provided with a type that defines multiple incompatible `operator()`
member functions.
This allows additional attributes to be attached to the internally
generated type such as move and destructor operations with no increase
in RAM footprint.
The current overloads can't take advantage of this, but it does open
the possibility for more powerful overloads that can provide these
additional attributes.
Changes to mbed-os memory consumption:
.text .data .bss
before 57887 2292 7692
after 57842 2292 7691
This change is not located in the hal because SDK v10 is not available from this
place. It is safe to provide the implementation in BLE because the SDK V10 is
defined there. Default implementations of critical section enter/exit are safe
as long as the softdevice is not used.
When the border router is switched off, the several retries will end up triggering the asserts in NanostackSocket::open. This is caused because socket_tbl elements, are never set to NULL.
Enable the low power timer for the following targets:
- NUCLEO_F411RE
- NUCLEO_F401RE
- DISCO_F429ZI
- NUCLEO_F446RE
- NUCLEO_F410RB
- DISCO_F469NI
- NUCLEO_F446ZE
- B86B_F446VE
This change allows a port to provide its own implementation of:
* core_util_critical_section_enter
* core_util_critical_section_exit
Some system like the NRF series require specific behavior for the critical
section and now can override it properly.
