Fri Jan 12 13:29:55 1996 Michael Meissner <meissner@tiktok.cygnus.com>
* scripttempl/elfppc.sc: Add support for .sdata2/.sbss2, etc. Add
in old support that 2.7.2 needs, but the current compiler does
not.
* Makefile.in (eelf32{,l}ppc.c): Fix up dependencies to use the
correct Linker script template.
* emulparams/elf32{,l}ppc.sh (TEXT_START_ADDR): Set to 0x40000,
not 0x400000.
(DATA_ADDR,NONPAGED_TEXT_START_ADDR): Delete.
Tue Jan 9 15:53:02 1996 Ian Lance Taylor <ian@cygnus.com>
* scripttempl/alpha.sc: Put .rconst right after .rdata.
