# genScript.sh

# a shell script to generate linker scripts.

# TODO:
|
||||
# 1. convenience labels like etext, edata, end, and wrs_kernel_*_{start,end}
|
||||
# are primarily used by ROM kernels and can most likely be omitted from RAM
|
||||
# kernels. But they're harmless and it makes script sharing easier.
|
||||
# 2. "classic" convenience labels (etext/edata/end) should be phased out in
|
||||
# favor of the newer ones. Further, DAT has requested that we make the new
|
||||
# names conform to wrsInitialCapitals style.
|
||||
# 3. Due to the template generation strategy employed here, the final output
|
||||
# may look a little awkwardly formatted and certainly is not as clean and
|
||||
# simple as the early versions of the Diab scripts. Suggestions welcome.
|
||||
# I actually think this might not be such a bad application for (gasp!) Tcl,
|
||||
# so a future Tcl rewrite (which also helps windows users) is possible.
|
||||
# 4. Currently GNU aligns everything to 16. This is probably overkill on many
|
||||
# chips, and especially once everyone is ELF, the internal section alignment
|
||||
# should take care of things -- except for convenience labels which need to
|
||||
# guarantee 4 byte alignment for use with copyLongs and fillLongs.
|
||||
# 5. General convergence...
