85 # A .sc script file is needed for each emulation mode.
86 # sed is used to transform this script into two variant forms:
87 # A .scr script is for linking without relocation (-r flag).
88 # A .scu script is like .scr, but *do* create constructors.
89 # A .scn script is for linking with -N flag (mix text and data on same page).
90 # A .scN script is for linking with -N flag (mix text and data on same page).
91 # The diference is that segments should (need) not be page aligned.

120 # with the text. Some other Unix variants do the same.
121 # For -n and -N flags the offset of the exec header must be removed.
122 # This sed script does this if the master script contains
123 # a line of the form ".text 0xAAAA BLOCK(0xBBBB):" - the
124 # output will contain ".text 0xBBBB:". (For Sunos AAAA=2020 and BBBB=2000.)

131 # with a hex constant that end with 00, since any normal page size is be
