* sysdeps/powerpc/bp-asm.h (DISCARD_BOUNDS): Rename from UNCHECK_BOUNDS.
* sysdeps/powerpc/bits/setjmp.h (JB_SIZE): New constant. * sysdeps/powerpc/elf/libc-start.c (__libc_start_main): Wrap bounds around argv & envp and each of their string members. * sysdeps/powerpc/elf/start.S: Designate BP symbols. * sysdeps/unix/sysv/linux/powerpc/brk.S: Wrap entry-point symbol in BP_SYM (). Discard bounds of address arg. * sysdeps/unix/sysv/linux/powerpc/clone.S: Likewise. * sysdeps/unix/sysv/linux/powerpc/mmap64.c (__mmap64): Discard bounds on address arg, add bounds to return value. 2000-07-21 Greg McGary <greg@mcgary.org> * sysdeps/powerpc/bp-asm.h (DISCARD_BOUNDS): Rename from UNCHECK_BOUNDS. * sysdeps/powerpc/bits/setjmp.h (JB_SIZE): New constant. * sysdeps/powerpc/elf/libc-start.c (__libc_start_main): Wrap bounds around argv & envp and each of their string members. * sysdeps/powerpc/elf/start.S: Designate BP symbols. * sysdeps/unix/sysv/linux/powerpc/brk.S: Wrap entry-point symbol in BP_SYM ().
