Patch rtems-rc-19991123-rc-2.diff from Ralf Corsepius
<corsepiu@faw.uni-ulm.de> which implements automake support for some score/cpu/<RTEMS_CPU> subdirectories and fixes a few minor configuration bugs. To apply: rm -rf c/src/exec/score/cpu/a29k/wrap rm -rf c/src/exec/score/cpu/hppa1.1/wrap rm -rf c/src/exec/score/cpu/i386/wrap rm -rf c/src/exec/score/cpu/mips64orion/wrap rm -rf c/src/exec/score/cpu/no_cpu/wrap patch -p1 < rtems-rc-19991123-rc-2.diff.gz Notes: * I don't see a possiblity to convert the powerpc subdirectory in its current layout to automake the time being. * Besides the fact that this subdirectory is not in single-tree building layout, the actual showstopper is the ifeq $(RTEMS_CPU_MODEL),mpc750) gmake-conditional in powerpc/Makefile.in, which automake (correctly) refuses to handle. * The problem is *not* specific to the powerpc. Other CPUs basically have similar problems (SH:sh7032 vs sh7045, SPARC: erc32.h in score/cpu/sparc), but have been lucky to get around real issues (cf. configuration files below score/cpu/sh/). * From a configuration focused POV this problem boils down to a file/subdirectory selection problem: ppc: 1 or others sh: 1 out of 2 sparc: 1 out of 1 Automake's means to implement such behavior is using conditionals to be evaluated at configuration-time. The old configuration scheme however used make-time conditionals. The SH port was lucky to get around this issue because it applies a selection from a limited set of possible selections, the powerpc however applies a selection from an unlimited set, based on data not being available at configuration time. * Currently I only see two general solutions: 1) make RTEMS_CPU_MODEL available at configuration time, ie. replace make-time configuration by configuration-time configuration 2) Perform the selection at build-time, i.e. always install all files, but use #ifdef #else #endif in source files. This is what the m68k has exploited at other locations inside of the source-tree. => This directory is the last one remaining not using automake below the whole exec/ hierarchy.
