| # Note: how the layout is done: |
| # we need to layout 2 segments, each contains sections: |
| # seg1: .data .dynamic |
| # seg2: .dynsym .dynstr .text .hash |
| # for each segment, we start from the first section, regardless |
| # whether it is an orphan or not (sections that are not listed in the |
| # linkerscript are orphans): |
| # for seg1, we assign address: .data(0x4000), .dynamic(0x4008) |
| # for seg2, we assign address: .dynsym(0x2000), .dynstr(0x2018) ... |
| # .dynsym is not an orphan, so we take address from script, we assign |
| # .dynstr current address cursor, which is the end # of .dynsym and so |
| # on for later sections. |
| |
| # Also note, it is absolutely *illegal* to have section addresses of |
| # the same segment in none-increasing order, authors of linker scripts |
| # must take responsibility to make sure this does not happen. |
