which adds partial automake support to libcpu/<cpu>/*.
Until now I have only implemented full automake support for the sh (my
demonstration example :) and the i386 (inevitiable for structural
reasons of this subdirectory). For all other cpus only their toplevel
directories (exception: powerpc), include subdirectories and a few
selected subdirectories have been converted to automake.
I did this on purpose, because add automake support to each subdirectory
requires individual adaptations which to be tested individually.
Additionally the weirdnesses of the powerpc subdirectories hit again,
esp. some powerpc cpu-models
* install files to $(PROJECT_INCLUDE)/<cpu-model>/ while others install
them to $(PROJECT_INCLUDE)/
* the scheme used to configure libcpu/powerpc/ is difficult to implement
using automake, therefore this subdirectory still is configured by
autoconf (The one out of an unlimited set selection scheme hits again
:), though powerpc/*/* subdirectories already apply automake.
The patch also reveils structural weaknesses in RTEMS:
E.g. There seem to exist at least 5 different general schemes:
* Not using libcpu at all (eg. i960)
* Strictly tree-style a libcpu/<cpu-variant>/* (eg. m68k, sh)
* Flat libcpu directory layout with cpu-variants merged into sources or
not destinguishing cpu-variants (i386)
* Not supporting variants with deep source tree (sparc, hppa, mips64orion)
* Woven directory structure with shared directories (powerpc)
I regret having to say this, but from my POV this means, that there
doesn't exist a general implementation scheme for libcpu at all.
To apply:
rm -rf ./c/src/lib/libcpu/i386/wrapup
rm -rf ./c/src/lib/libcpu/mips64orion/include
rm -rf ./c/src/lib/libcpu/powerpc/ppc403/include
