esp_common/shared_stack: refactored the implemenation of shared stack function (still not working properly)
esp_expression_with_stack: refactored the shared stack function calling mechanism and updated the documentation
Since in b0491307, which has introduced the optimized window spill
procedure, _xt_context_save did not work correctly when called from
_xt_syscall_exc. This was because unlike _xt_lowint1, _xt_syscall_exc
does not save PS and EPC1. The new version of _xt_context_save
modified PS (on purpose) and EPC1 (accidentally, due to window
overflow exceptions), which resulted in a crash upon 'rfi' from the
syscall.
This commit adds restoring of PS and EPC1 in _xt_context_save. It also
slightly reduces the number of instructions used to prepare PS for
window spill.
Unit test for setjmp/longjmp (which were broken by this regression)
is added.
Closes https://github.com/espressif/esp-idf/issues/4541
Using xxx_periph.h in whole IDF instead of xxx_reg.h, xxx_struct.h, xxx_channel.h ... .
Cleaned up header files from unnecessary headers (releated to soc/... headers).
Fixed adjtime function: While using the adjtime() function,
the time correction accumulated an error
when reading the time frequently (using gettimeofday).
New unity component can be used for testing other applications.
Upstream version of Unity is included as a submodule.
Utilities specific to ESP-IDF unit tests (partitions, leak checking
setup/teardown functions, etc) are kept only in unit-test-app.
Kconfig options are added to allow disabling certain Unity features.
This function speeds up or slows down the system clock in order to make a gradual adjustment. This ensures
that the calendar time reported by the system clock is always monotonically increasing, which might not happen
if you simply set the clock.
The delta argument specifies a relative adjustment to be made to the clock time. If negative, the system clock is
slowed down for a while until it has lost this much elapsed time. If positive, the system clock is speeded up for a
while.
If the olddelta argument is not a null pointer, the adjtime function returns information about any previous time
adjustment that has not yet completed.
The return value is 0 on success and -1 on failure.
To stop the adjustement, call the function settimeofday(current_time).
In some cases (when RTC register reads are performed from the APP CPU), a write to FRC_TIMER_INT_REG may be lost on the bus.
Writing to another DPORT register immediately before or after that works around the issue.
We write one dummy value to an address which doesn’t have any register associated with it.
Fixes https://github.com/espressif/arduino-esp32/issues/120
- add two versions of libc: libc.a and libc_nano.a. First one has full C99 formatting support, second one uses “nano” formatting functions available in ROM.
- fix linker error for fmod, fmodf, atof, atoff
- update tests
