this will reduce confusion when searching for FLIGHT_LAND_* and you get a bunch of takeoff related hits. It will also make more sense when the landing library fully manages the FLIGHT_LAND stage entirely because it will not mange FLIGHT_LAND_ABORT
This commit changes the way libraries headers are included in source files:
- If the header is in the same directory the source belongs to, so the
notation '#include ""' is used with the path relative to the directory
containing the source.
- If the header is outside the directory containing the source, then we use
the notation '#include <>' with the path relative to libraries folder.
Some of the advantages of such approach:
- Only one search path for libraries headers.
- OSs like Windows may have a better lookup time.
It both reduces flash size and move symbols to read-only sections.
The scheduler_tasks table is one known not to be in read-only section before due
to the FastDelegate implementation. Before and after this patch:
APMrover2 $ size APMrover2.elf{.old,}
text data bss dec hex filename
611406 4832 40920 657158 a0706 APMrover2.elf.old
609686 4824 38936 653446 9f886 APMrover2.elf
APMrover2 $ nm -C APMrover2.elf{.old,} |grep tasks
0000000000696f80 B Rover::scheduler_tasks
000000000047c440 R Rover::scheduler_tasks
As can be seen above, now the scheduler_tasks symbol is in a read-only data
section and in all of them we decreased the total size.
For APM2 we have a similar situation, but the table was already in text section
because it was using plain C pointers:
APMrover2 $ size APMrover2.elf{.old,}
text data bss dec hex filename
189518 1038 3494 194050 2f602 APMrover2.elf.old
189216 1038 3480 193734 2f4c6 APMrover2.elf
APMrover2 $ nm -C APMrover2.elf{.old,} |grep tasks
00001f92 T Rover::scheduler_tasks
00001f8a T Rover::scheduler_tasks
Start to add code behind APM_BUILD_FUNCTOR to support changing the
functor implementation (without breaking the build while the change is
not complete).
