  121. +This file details the diffs, patches and new files needed to allow GNU gcc
  122. +to support A/UX. Most of these are required due to the hybrid nature of
  123. +A/UX (UNIX and MacOS) and some are simply to describe A/UX itself. Builds
  124. +of gcc for A/UX require 'gas' (at least 1.38.1) and a previously built
  125. +version of 'gcc'. Check the A/UX FAQ for sites that carry these.
  126. +
  127. + * Makefile.in (libgcc2.a): Allow object files in LIB2FUNCS_EXTRA
  128. + so that objects needing special processing can be added.
  129. +
  130. + * c-lex.c (readescape, yylex): Provide support for the pascal
  131. + strings used by Mac programmers.
  132. + * c-lex.c (yylex): Conditionally do not produce a warning for
  133. + multi-character constants under A/UX.
  134. +
  135. + * m68k/aux-exit.c: New file. Provides _exithk() stub for MacOS
  136. + * m68k/aux-crtfix.c: New file. Provide tool to patch MacOS mcrt files
  137. + * m68k/aux-mcount.asm: New file. Hook into A/UX profiling.
  138. + * m68k/aux.h, m68k/x-aux, m68k/xm-aux.h: New files.
  139. +
  140. + * m68k/m68k.c (use_return_insn): A/UX returns pointers in %a0 --
  141. + don't use return insn when returning a pointer.
  142. +
  143. + * gcc.c (process_command): A/UX's 'ld' requires a space
  144. + between after '-o' but no space after '-L'
  145. +
  146. + * libgcc2.c: Add in _exithk() stub to exit() call.
  147. +
  148. + * configure, config.guess, config.sub: Recognize A/UX.
  149. +
  150. + * fixincludes: Fix A/UX's <sys/param.h>.
  151. +
  152. + * aux-fixcrts: New file. Uses aux-crtfix to fix MacOS mcrt files.
  153. +
  154. +These patches follow the tradition of placing the gcc executable in
  155. +'/usr/local/Gnu' and the support files in '/usr/local/Gnu/lib/gcc/aux'
  156. +
  157. +To build A/UX the procedure is quite easy and follows the general 'gcc'
  158. +methods. However, the previously built version of 'gas' must be placed
  159. +at the top-level source directory and called 'as'. If you're kinda lazy,
  160. +you do this in the top-level directory of the gcc-2.7.2 source tree:
  161. +
  162. + % cp <gas's home>gas as
  163. + % patch < gcc4aux.diffs
  164. + % ./configure --prefix=/usr/local/Gnu aux
  165. + % make CC="<pathname to gcc>"
  166. + % make stage1
  167. + % make CC="stage1/xgcc -Bstage1/"
  168. + % make stage2
  169. + % make CC="stage2/xgcc -Bstage2/"
  170. + % make CC="stage2/xgcc -Bstage2/" compare
  171. + % make CC="stage2/xgcc -Bstage2/" install
  172. + % make CC="stage2/xgcc -Bstage2/" objc-runtime
  173. + % make CC="stage2/xgcc -Bstage2/" install-libobjc
  174. +
  175. +Finally, when built, it is recommended that you run 'aux-fixcrts' to
  176. +patch the MacOS mcrt files to work under 'gcc' if you will be creating
  177. +MacOS-hybrid programs. The command-line is:
  178. +
  179. + % sh aux-fixcrts /usr/local/Gnu/lib/gcc/aux/2.7.2
  180. +
  181. +Enjoy!

  183. +NOTE: These patches are the result of work of a lot of contributors including:
