crt0.o from newlib has ARM32-only routines when building gcc for arm-eabi

crt0.o from newlib has ARM32-only routines when building gcc for arm-eabi

[David Fernandez]

Hi there,

I've been building a arm-eabi toolchain recently, using binutils-2.22,
gcc-4.7.1 and newlib-1.20.0 (I think).

The problem is that when I build for cortex-m3 (-march=armv7-m
-mcpu=cortex-m3 -mthumb), I get the routine _CRTStartup assembled as
ARM32 (definitely not thumb or thumb-2). The file crt0.o seems generated
during gcc build.

Is that expected? As crt0.S in newlib has #ifdefs to choose the right
thumb-2, thumb or ARM specific assembler depending on the predefined macros.

The only thing I can think of is that it might be forced by the gcc
build system, perhaps because linux does not support thumb-only
platforms (?)...

It might be a very silly thing, but if anybody could tell what is the
problem, it would be great.

Cheers
David Fernandez

look for compiler cmdline when this was compiled. Did you use --with-mode=thumb
when configuring the compiler ?

Gosh! I didn't. No idea that it needed a special parameter to have thumb
only mode... even for a CPU that will refuse to compile without "-mthumb"...

Thanks for the tip. I'll try that soon.

It fails if I use "--with-mode=thumb"

The configuration goes ok (I use "configure --target=arm-eabi
--enable-languages=c,c++ --with-gnu-as --with-gnu-ld --with-newlib
--with-gxx-include-dir=/usr/local/arm-eabi/include --with-mode=thumb
-v"), but when doing "make -w all", it fails when it tries multilib:

...
make[2]: Leaving directory
`/home/user/rpmbuild/BUILDROOT/arm-eabi/gcc-4.7.1/gcc'
Checking multilib configuration for libgcc...
mkdir -p -- arm-eabi/libgcc
...
checking for suffix of object files... o
...
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.
make[1]: *** [configure-target-libgcc] Error 1
make[1]: Leaving directory

make: *** [all] Error 2
make: Leaving directory `/home/user/rpmbuild/BUILDROOT/arm-eabi/gcc-4.7.1'

Any ideas?

I've tried --disable-fpu instead of --disable-decimal-float, but it
fails when building libgloss (I guess the one from newlib):

That was the problem! (no need to add --disable-decimal-float, which
is disabled by default on arm targets). Thanks very much!

I guess this poses a few questions:

Should there be several crt0.o files available, that gcc should pick
depending on the -mthumb, -march, and -mcpu?

Is it that gcc is not quite there yet, or that newlib is not yet
compatible enough with the gcc multilib build system?

Any gcc guru knows something about this? As otherwise, the --target
configuration option does not produce a compiler supporting all the
cpus and architectures that the target covers in theory, and then
perhaps there should be a default prefix/suffix for the executables
and folders depending on the --with-cpu and/or --with-arch...

Cheers

mthumb means either thumb1 or thumb2 depending on -mcpu
so newlib has to  be told that

I don't deny that newlib needs to be compiled per cpu... I'm just
guessing here that the standard libc would work with any cpu and mode
covered by the selected target, while, with newlib, we have to
recompile the whole gcc with different options for the same target to
support all the cpus in that target.

I guess that another options is: Shouldn't we be splitting the
arm-eabi target on subsets of compatible cpus, like
--target=arm-eabi-cortex-m3, etc.?
