- Add support of cortex-M7 for cthunk.
- Change the cthunk trampoline implementation to safer and quicker
solutions:
* thumb2, the behaviour was undefined. new implementation use now 2
instructions
* thumb, The new implementation use 3 instructions instead of 6.
This commit adds a dynamic memory tracer that calls a callback whenever
one of the basic memory allocation functions (malloc, realloc, calloc,
free) is called. The operation of the tracer is guarded by the
'MBED_MEM_TRACING_ENABLED` macro.
Infinite recursion during tracing is guarded by using atomic
increment/decrement primitives on the `trace_level` variable.
Thanks to @c1728p9 and @heky for their help and suggestions.
Keep track of the current size allocated, maximum size allocated,
number of allocations, failed allocations and total size allocated for
both GCC and ARM. Report the maximum size allocated at the end of
testing.
Also, add a test to verify heap metrics are working as expected.
Check to see if ptr is NULL after acquiring the singleton lock to
prevent initialization race conditions. Also explicitly call the
constructor for type T.
From the discussion on issue #2068:
Functions marked deprecated in the mbed library should notate when
the deprecation was started to allow efficient removal once a set
amount of time has expired.
Added the following macro:
MBED_DEPRECATED_SINCE("version", "message string")
Example usage:
MBED_DEPRECATED_SINCE("v5.1", "don't foo any more, bar instead")
void foo(int arg);
Adopted in existing deprecations:
- FunctionPointer
- RtosTimer
- Thread
Currently this uses the same mechanism used by the rtos to conditionally
include the network-socket API. Perhaps this should be builtin to the
config system?
Note: this does require that the bug-compatible inclusion of mbed.h
be removed to avoid include-order issues.
per @sg-
Before, the following results in a compilation error:
const struct Object *obj;
void obj_doit(const Object *obj);
Callback<void()> cb(obj, obj_doit);
This is especially noticable when migrating from the old Thread
constructor, which previously _required_ const.
Short term fix for all cv qualifiers through a C cast:
void *_obj = (void*)obj;
FunctionPointer/FunctionPointerArg0/FunctionPointerArg1 has been
replaced by the more flexible Callback template class.
For the motivation behind adopting the Callback class:

Create the wrapper class SingletonPtr. This provides a safe way to
declare and use singletons. This class allows both the lazy
initialization of a singleton, and allows the singleton to be
garbage collected by the linker if it is never referenced.
This patch also updates the HAL to use SingletonPtr when declaring
singleton mutexes.
and update the using functions accordingly.
Usage:
bool interrupts_enabled = are_interrupts_enabled()
Remove superfluos shift in are_interrupts_enabled().
than an integer. This removes the need for all users to mask the returned
value with 0x1 to determine interrupt status.
Expose this function externally to allow other users to check interrupt
status in a manner which will work for both cortex-A and cortex-M .
Usage:
bool disabled = get_interrupts_disabled();
Add a virtual destructor to classes which have a virtual lock and
unlock. Remove the virtual qualifier from functions in
InterruptManager since this class cannot be extended.
This includes a generic critical section implementation. This
implementation also allow a user to start a critical section while
interrupts are already disabled.
