Here is a enhanced version of my previous patch. This patch enables
to potentially share the new interrupt management code for all Intel targets
(pc386, go32 and force386) bsp.
Note : this patch is complete only for pc386. It still needs to
be completed for go32 and force386. I carrefully checked
that anything needed is in for force386 (only some function
name changes for IDT manipulation and GDT segment
manipulation). But anyway I will not be able to test any
of theses targets...

+ DEBUG_EARLY_START re-added (Eric Valette)
+ segment register initialization (Aleksey/Quality Quorum)
+ heap size use correction
+ more debug printk's
+ increased heap size.
Now works with grub boot on all systems I have access to including
desktops and a laptop. This is with the i386-rtems tools.
Neither i386-rtemself nor netboot produces a working executable.

The breakdown:
* CC_FOR_TARGET and CXX_FOR_TARGET were not correctly re-read
from autoconf's configuration cache (config.cache)
* If <target>-[gcc|g++] was not found while running configure,
the config macros tried to use other (wrong) compilers (e.g. cc).
Changes:
* New RTEMS_PROG_CC macro (aclocal/prog-cc.m4).
* New RTEMS_PROG_CXX macro (aclocal/prog-cxx.m4)
* Moved a shell script fragment from configure.in to a
new m4-autoconf macro (New file: aclocal/tool-prefix.m4)
* Minor changes to configure.in
I tested it with linux/posix (native gcc/primary libc) and
sh-rtems/gensh1 on a linux host and didn't notice any bugs
related to the problems mentioned above. There seem to be
more bugs with the posix bsp, but I consider them minor as
the build run completed successfully. It is just too late
for me to attempt to fix them now.

code in each BSP's bspstart.c. These changes were:
+ confdefs.h now knows libio's semaphore requirements
+ shared/main.c now copies Configuration to BSP_Configuration
+ shared/main.c fills in the Cpu_table with default values
This removed the need for rtems_libio_config() and the constant
BSP_LIBIO_MAX_FDS in every BSP. Plus now the maximum number of open
files can now be set on the gcc command line.

at system initialization time and avoids the BSP having to
even know about its existence.

based on the GNU tools. This usually involved correcting the
type of bsp_start(), bsp_cleanup(), adjusting the start code to
call the right start routine (the shared boot_card()), and then
removing code from bsp_start() which was performed in the new
boot_card()/main() path.

Here is the result of my nightly work to get RTEMS_ROOT=$srcdir working
with different shells and relative/absolute paths.
What I did is relatively simple in principle:
Instead of setting RTEMS_ROOT in configure.in and then let configure
substitute @RTEMS_ROOT@ inside the Makefiles, I now let each Makefile
set RTEMS_ROOT from each Makefile's @top_srcdir@ value.
The difference is subtile, but with enormous side effects:
- If RTEMS_ROOT is set in configure, then the same single value will be
propagated to all Makefiles. This breaks using relative paths, as the
relative path to the root of the source tree is used inside of all
subdirectory Makefiles.
- Now each Makefile.in sets RTEMS_ROOT = @top_srcdir@. top_srcdir is
computed individually by configure for each single Makefile.in, hereby
receiving the correct value, no matter if relative or absolute paths are
used.
To get this working, I needed to remove setting RTEMS_ROOT from
target.cfg.in, because this overrides the value of RTEMS_ROOT from each
individual Makefile.
Furthermore, I removed RTEMS_CUSTOM from the Makefiles and replaced all
"include $(RTEMS_CUSTOM)" directives with"include
$(RTEMS_ROOT)/make/custom/$(RTEMS_BSP)". Perhaps you don't like this,
but I think, to have one variable less is clearer and easier to
understand than having several variables refering to the next one.
I enclose a small patch to this mail, which
- fixes the config.h problem (to finally clearify misunderstands)
- removes assignment/subsitution of RTEMS_ROOT from configure.in
- contains a workaround for the application Makefile's RTEMS_ROOT
problem (reported by Eric)
- removes some unused lines from the toplevel Makefile.in
- removes assignment of RTEMS_ROOT from make/target.cfg.in

before the command "gmake" is invoked is RTEMS_BSP (e.g. RTEMS_BSP=erc32).
