   1 # Linker script for TI TMS320C80 (tic80) COFF.
   2 #
   3 # Besides the shell variables set by the emulparams script, and the LD_FLAG
   4 # variable, the genscripts.sh script will set the following variables for each
   5 # time this script is run to generate one of the linker scripts for ldscripts:
   6 #
   7 # RELOCATING: Set to a non-empty string when the linker is going to be doing
   8 # a final relocation.
   9 #
  10 # CONSTRUCTING: Set to a non-empty string when the linker is going to be
  11 # building global constructor and destructor tables.
  12 #
  13 # DATA_ALIGNMENT: Set to an ALIGN expression when the output should be page
  14 # aligned, or to "." when generating the -N script.
  15 #
  16 # CREATE_SHLIB: Set to a non-empty string when generating a script for
  17 # the -shared linker arg.
