I have be playing with creating my own crt0.o to be loaded by `ld'. My `crt0.s' roughly looks like: .file "crt0.s" .text .align 16 .org 0x3a00 start: bsr ?_main .... etc Compiling this with a simple "hello world" program, and then running `aoutdump' on the resultant `a.out', the physical address of the text segment does NOT show as being at 0x3a00. It instead shows it as being at 0x0 with a size a little bigger than 0x3a00. What it IS doing is indeed putting `start' at 0x3a00, but prepending 0x3a00 zeros. I don't want that because that is a waste. I don't want all of the leading zeros. How can I get `ld' to NOT prepend all the zeros? It is a waste to be able to specify the physical address in the a.out header (scnhdr(5) -> s_paddr) and then not make use of it. Thanks in advance for any ideas/thoughts/suggestion/comments/etc....
