[ECOS] order of calling for static initializers
Mon Nov 27 21:22:00 GMT 2006
The '#define' statements that control the order in which statics get
called at startup (as defined in cyg_type.h) looks reasonable to me:
#define CYG_INIT_HAL 10000
#define CYG_INIT_SCHEDULER 11000
#define CYG_INIT_INTERRUPTS 12000
#define CYG_INIT_DRIVERS 13000
#define CYG_INIT_CLOCK 14000
#define CYG_INIT_IDLE_THREAD 15000
The list is populated in the linker script with SORT. Fine. But the
code that calls them (for the platforms I looked at) goes thru the list
in reverse order.
So, in my code, the idle thread gets initialized before the scheduler.
This means that set_idle_thread sets the idle thread in the scheduler,
but then this gets lost when the scheduler initializes. This must be wrong.
I am using a different compiler (Code Sorcery) and had to compensate
accordingly, so my problem probably starts there, but I don't understand
what I am doing wrong. It looks like things are being initialized in
the reverse order on purpose. I tried simply reversing the order in
which things were called, but that caused other problems.
