Maybe something like this?  Subject to the usual disclaimers about
syntax and the like--- I'm making this up as I go, not copying from a
source file...


typedef struct {
	void* stack;
	void(*pc)(void);
} reset_vector_T;

const reset_vector_T reset_vector =
{
	0xb40000,
	main
} __attribute((section".vect")))

...

MEMORY {
	vect (rx) : origin=0, len=8
...
}

SECTIONS {
	.vect : { *(.vect) } >vect
...
}



HTH,
