OK more progress made...
Using objcopy and readelf i have figured out the problem. and that is:
the .vectors section needs the flags of "ax" and needs to be of type progbits
so if you use the .section .vectors you will need to specify this.
like:
.section .vectors,"ax",@progbits
.word symbol
....
I found this to work very well all the vector bits are set in memory now my
assembler programs are working correctly and have all appropriate vectors
assigned.
WHEW! that was fun.
