# 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.
