Add asm sources which provide a fixed entry point for raw bootxx and bootxxx
because modern aggressive gcc4 may reorder functions in the same source
and the first function in a C source won't always appear at the beginning
in its object.
Also overhaul various files in the stand directory:
- rename stand/Makefile.inc to stand/Makefile.booters and
explicitly include it from each Makefile because the stand
directory contains non standalone programs like installboot and
Makefile.inc will be included implicitly from all Makefiles in SUBDIRs
- put more common options into Makefile.booters so that
all boot programs use proper options (-Os etc.)
- make standalone boot programs compile without installed ${DESTDIR}:
- create machine and m68k symlinks in ${.OBJDIR} in all boot programs
- set appropriate make environments to suppress errors and warnings
- <string.h> isn't there in _STANDALONE case
- put #ifdef TOSTOOLS (looks equivarent with !_STANDALONE)
to some files in stand/tostools
- use ${LD} ${LINKFLAGS} rather than ${CC} ${LDFLAGS}
- create raw binaries on ${PROG} target rather than on beforeinstall
and stop weird renaming on beforeinstall and afterinstall
- print proper error message if bootxx size is larger than limit
- create ${DESTDIR}/usr/mdec/{milan,std} directories on beforeinstall
in all boot programs
(XXX: how can we put MD /usr/mdec/foo directories into src/etc/mtree?)
- prototype warnsfy
- cleanup Makefiles for readablity and remove unnecessary rules
- no need to use daddr_t in installboot because the AHDI label doesn't
support 64 bit block numbers
Tested by David Ross (PR submitter) on port-atari, and
finally NetBSD/atari on TT030 is now fully functional.
Should be pulled up to netbsd-4 (where gcc4 was initially imported)
and netbsd-5.
