# $NetBSD: Makefile,v 1.13 1997/07/14 15:03:05 veego Exp $
First version of a NetBSD-Amiga bootblock compilable from within NetBSD, along with toolchain enhancements. aout2bb transforms a.out files with reloc information into bootblock format files with a compressed relocation info. bbstart.s relocates the bootblock using this compressed info, before jumping to C code. txlt changes some more of the absolute references to pc-relative ones (we know we have a single code + data address space). If you ever try to change this: don't even dare to change the compiler options; they were found in weeks of trial and error as the ones producing the smallest (not necessarily fastests) code. installboot is just a script around dd, for now. Some ideas by Michael Hitch, Leo Weppelman and Jason Thorpe; bugs added by myself.

* make object dirs work: - move the helper programs txlt and aout2bb to the topmost directory - build the few files from libsa in the topmost directory * while doing this, hunted down mysterious code expansion: It seems that ld aligns code segments differently when linking .o's directly than when using an archive consisting of the same files. Abuse this effect to make the bootblock even smaller. The floppy boot block "fdboot" is now small enough to build; add it back to the Makefile. * while being here, remove a file which was committed by mistake.

* make object dirs work: - move the helper programs txlt and aout2bb to the topmost directory - build the few files from libsa in the topmost directory * while doing this, hunted down mysterious code expansion: It seems that ld aligns code segments differently when linking .o's directly than when using an archive consisting of the same files. Abuse this effect to make the bootblock even smaller. The floppy boot block "fdboot" is now small enough to build; add it back to the Makefile. * while being here, remove a file which was committed by mistake.

Yet another try to sanitize the bootblock build. Each major target has now its own subdirectory. Smaller changes involved: - installboot installs to /usr/mdec - installboot.8 installs to /usr/share/man/cat8/amiga/

First version of a NetBSD-Amiga bootblock compilable from within NetBSD, along with toolchain enhancements. aout2bb transforms a.out files with reloc information into bootblock format files with a compressed relocation info. bbstart.s relocates the bootblock using this compressed info, before jumping to C code. txlt changes some more of the absolute references to pc-relative ones (we know we have a single code + data address space). If you ever try to change this: don't even dare to change the compiler options; they were found in weeks of trial and error as the ones producing the smallest (not necessarily fastests) code. installboot is just a script around dd, for now. Some ideas by Michael Hitch, Leo Weppelman and Jason Thorpe; bugs added by myself.
