# genscripts.sh - generate the ld-emulation-target specific files
#
# Usage: genscripts.sh srcdir libdir host_alias target_alias \
# default_emulation this_emulation
#
* ldmain.c (main): Don't add scriptdir to the lib search path. * genscripts.sh: Put the scripts in the ldscripts directory, not emulations. * configure.in (ldscripts): Make, instead of emulations. * Makefile.in (scriptdir): Take off the "ld" part. (install, clean, distclean): Use ldscripts, not emulations. In tests, pass -L., not -Lemulations. (ldmain.o): Don't pass -DSCRIPTDIR=.... * ldlang.c (lang_process): Add "ldscripts/" to the name of the default script file.
