Fix the caller address logging on the GCC compilation too.
Previously the code logged the caller address as C++ wrapper,
not the actual caller of the C++ operator new or delete.
The C++ "operator new" and "operator delete" (and their array
variants) were logging the the caller address wrong. In practice
if one used "operator new", the logged caller address pointed
to mbed_retarget.cpp, not to the client. Fix this by exposing
the alloc wrappers to the the retarget.
Note: this fixes only the ARMCC variants, as the GCC ones have
different different API and implementation.
For each of the following years test example time of the first and last day of each month:
- first - 1970
- example not leap year (not divisible by 4)
- example leap year (divisible by 4 and by 100 and by 400)
- example leap year (divisible by 4 and not by 100)
- example not leap year (divisible by 4 and by 100)
- last fully supported - 2105
Test execution time on K64F is now ~39 sec.
Call underlying HAL implementation to enter critical section/disable interrupts
before incrementing the global critical section counter.
Modify HAL implementations to track first entrances to the critical section and
only update the saved state on first enter.
- Define header functions for Critical Section HAL API
- hal_critical_section_enter()
- hal_critical_section_exit()
- Add weak default implementation for HAL API. The default implementation
matches the previous behaviour stored in mbed_critical:
- The first call to enter a critical section stores the state of interrupts
before disabling and each successive call re-disables interrupts.
- The last call (non-nested) will restore the IRQ state that was set on the
enter to the critical section. Nested calls are ignored.
- Add function 'core_util_in_critical_section' to User facing API to determine
if the program is currently in a critical section, instead of depending on
'core_util_interrupts_enabled'.
Take SHA1 for example, without the fix, SHA H/W is not stopped in either case:
(1) ctx->total == 0 in mbedtls_sha1_hw_finish()
(2) mbedtls_sha1_hw_finish() is not called by upper layer
