lr-gpsp:
cpu_threaded.c built with -O2 on gcc 8 produces a non working binary. This source already had
a different optimisation level from the rest of the code (O2 vs O3). However, on gcc-8 it causes
a non working binary when built with anything other than O0, but this could have some performance
issues (would need testing on a rpi1).
I compared all the different optimisation flags enabled by O1 and also with any changes from gcc-6,
but not all GCC optimisations are controllable from flags. It was not possible to produce a working
binary with O1 - even disabling all the configurable optimisations enabled by O1.
The issue is most likely undefined behaviour in this file (which has a lot of large macros), and it
probably needs some fixes. However it could be a bug in the gcc-8 optimiser code.
As the issue isn't present with gcc-6, and as gcc-6 is available on Debian buster, the easiest
workaround is to just force the code to be build with gcc-6.
Also adjusted the makefile to pass parameters for the make clean, as some platform specific objects
are not removed otherwise.
gpsp:
Forced gcc-6 as with lr-gpsp.
Simplified the module flags to just include videocore platforms.
* rp_module_menus is no more - instead use rp_module_section with one of
- core (core packages)
- main (main packages - which will be installed by default in the image)
- opt (optional packages)
- exp (experimental packages)
- driver (driver packages)
- config (configuration packages / tools)
* The setup menu organises the data based on the above sections. more could be added in the future if needed. Packages (internally modules), can be added / configured / removed individually, or as entire sections.
* The setup menu will automatically detect if a binary is available to be installed. the nobin flag is no longer needed. modules that install directly from binary via aptInstall or via a prebuilt binary need to use an install_bin_ function instead of install_
* rp_module_section of type "config" will have the "gui_" function called first if it's available, otherwise a standard depends/sources/build/install/configure will be called
* configure is no longer used for "gui" configuration function - use gui_ instead. Had already started to move to this before, but now it is required.
