2001-05-22 Alexandre Oliva <aoliva@redhat.com>
* emulparams/elf_i386_ldso.sh: New, copied from elf_i386.sh.
(ELF_INTERPRETER_NAME): Define it.
* emultempl/elf32.em (gld${EMULATION_NAME}_before_allocation): Use
it.
* configure.tgt (targ_emul, targ_extra_emuls)
[i[3456]86-*-solaris2*, i[3456]86-*-solaris*]: Use elf_i386_ldso
as primary, elf_i386 as extra.
* Makefile.am (ALL_EMULATIONS): Added eelf_i386_ldso.o.
(eelf_i386_ldso.c): New rule.
* Makefile.in: Rebuilt.
2001-05-22 Nick Clifton <nickc@redhat.com>
* lexsup.c (ld_options): Allow -I to be an alias for
--dynamic-linker. This is for Solaris compatability.
* ld.texinfo: Document that -I can be used.
* ld.1: Regenerate.
2001-05-16 Alan Modra <amodra@one.net.au>
* ldlang.c (wild_doit): Use linker_has_input to reliably determine
