57 | # sun3.x [default linker script] | |
58 | # sun3.xbn [used when the linker is invoked with "-N"] | |
59 | # sun3.xn [used when the linker is invoked with "-n"] | |
60 | # sun3.xr [used when the linker is invoked with "-r"] | |
61 | # sun3.xu [used when the linker is invoked with "-Ur"] | |
62 | # and maybe: | |
63 | # sun3.xc [used when the linker is invoked with "-z combreloc"] | |
64 | # sun3.xsc [used when the linker is invoked with "--shared"] | |
65 | # sun3.xdc [used when the linker is invoked with "-pie"] | |
66 | # | |
67 | # It also produced the C source file: | |
68 | # | |
69 | # em_sun3.c | |
70 | # | |
71 | # which is then compiled into the linker. | |
72 | # | |
73 | # The linker scripts are created by running the shell script | |
74 | # /sources/ld/emulparams/sparc.sh to set the value of ${SCRIPT_NAME} | |
75 | # (and any other variables it wants to). ${SCRIPT_NAME} is then | |
76 | # invoked with a variable called ${LD_FLAG} to tell it which version | |
77 | # of the linker script to create. | |
