2004-08-30 Anthony Green <green@redhat.com>
* Makefile.am: Add frv support.
* Makefile.in, testsuite/Makefile.in: Rebuilt.
* configure.ac: Read configure.host.
* configure, aclocal.m4: Rebuilt.
* configure.host: New file. frv-elf needs libgloss.
* include/ffi.h.in: Force ffi_closure to have a nice big (8)
alignment. This is needed to frv and should harm the others.
* include/ffi_common.h (ALIGN_DOWN): New macro.
* src/frv/ffi.c, src/frv/ffitarget.h, src/frv/eabi.S: New files.
