arm[eb]-eabi-gcc for cortex-r4[f] with newlib has problems with multilib/libraries.

[David Fernandez]

Hi there,

I've built an arm[eb]-eabi-gcc for --with-cpu=cortex-r4[f]
--with-mode=thumb --with-newlib, both manually and with crosstool-ng. In
all cases, I get a strange problem when building a main function with
ful C runtime library support like this (include the latest version, but
it happens with the little endian, and with the cortex-r4 too):

$ armeb-eabi-gcc -mbig-endian -mthumb -march=armv7-r -mcpu=cortex-r4f -o
alignpack alignpack.c
/opt/x-tools/armeb-unknown-eabi/lib/gcc/armeb-unknown-eabi/4.7.2/../../../../armeb-unknown-eabi/bin/ld:
error:
/opt/x-tools/armeb-unknown-eabi/lib/gcc/armeb-unknown-eabi/4.7.2/../../../../armeb-unknown-eabi/lib/libc.a(lib_a-strlen-armv7.o):
Conflicting architecture profiles A/R
/opt/x-tools/armeb-unknown-eabi/lib/gcc/armeb-unknown-eabi/4.7.2/../../../../armeb-unknown-eabi/bin/ld:

/opt/x-tools/armeb-unknown-eabi/lib/gcc/armeb-unknown-eabi/4.7.2/../../../../armeb-unknown-eabi/lib/libc.a(lib_a-strlen-armv7.o)
collect2: error: ld returned 1 exit status

I'm pretty sure that when I built this same kind of compiler for a
cortex-m3, it did not do this.

Anyway, find attached the alignpack.c, and the crosstool-ng log. I had
to use newlib-2.0.0 to make it work with the tuple armeb-xxx.

I've tried additional multilib permutations, but the errors keep appearing.

Any thoughts?

Regards.
