Subject: [PATCH] configure.in (mips*-*-*): Add a test to see if MIPS libgloss
linker scripts use STARTUP directives...
2002-07-29 Chris Demetriou <cgd@broadcom.com>
* configure.in (mips*-*-*): Add a test to see if MIPS libgloss
linker scripts use STARTUP directives consistently.
* configure: Regenerate.
* config.in: Regenerate.
* config/mips/elf.h (STARTFILE_SPEC): Define conditionally, based
on whether HAVE_MIPS_LIBGLOSS_STARTUP_DIRECTIVES is defined.
* config/mips/elf64.h (STARTFILE_SPEC): Likewise.
* config/mips/isa3264.h (STARTFILE_SPEC): Do not redefine if
HAVE_MIPS_LIBGLOSS_STARTUP_DIRECTIVES is set; the result
will be the same.
