Building newlib-1.15.0 with gcc-4.3.0 for arm-elf

Building newlib-1.15.0 with gcc-4.3.0 for arm-elf

[Mariusz Janiak]

Hi,

I have problem during compilation of the newlib-1.15.0 using gcc-4.3.0. Target is arm-elf.

The exact version of GCC, the system type, the options given when GCC was configured/built:

Target: arm-elf
Configured with: ../gcc-4.3.0/configure --target=arm-elf --prefix=/opt/gnuarm-4.3.0 --enable-interwork --enable-multilib --with-float=soft --enable-languages=c,c++ --with-newlib --with-headers=../newlib-1.15.0/newlib/libc/include --with-mpfr=/usr/local
Thread model: single
gcc version 4.3.0 (GCC)

The complete command line that triggers the bug:

arm-elf-gcc -B/home/mjaniak/tmp/install/GNUARM/gcc-4.3.0/build-newlib/arm-elf/newlib/ -isystem /home/mjaniak/tmp/install/GNUARM/gcc-4.3.0/build-newlib/arm-elf/newlib/targ-include -isystem /home/mjaniak/tmp/install/GNUARM/gcc-4.3.0/newlib-1.15.0/newlib/libc/include -O2 -DARM_RDI_MONITOR -fno-builtin   -mthumb -march=armv7 -c -o lib_a-setjmp.o `test -f 'setjmp.S' || echo '../../../../../../../../newlib-1.15.0/newlib/libc/machine/arm/'`setjmp.S

The compiler output:

../../../../../../../../newlib-1.15.0/newlib/libc/machine/arm/setjmp.S: Assembler messages:
../../../../../../../../newlib-1.15.0/newlib/libc/machine/arm/setjmp.S:123: Error: SP not allowed in register list -- `stmea a1!,{v1-v7,fp,ip,sp,lr}'
../../../../../../../../newlib-1.15.0/newlib/libc/machine/arm/setjmp.S:145: Error: SP not allowed in register list -- `ldmfd a1!,{v1-v7,fp,ip,sp,lr}'

This is an assembler error for a .S file, which means it has nothing to 
do with gcc.  It is either a newlib bug or a binutils bug.  Probably a 
newlib bug.  Looks like newlib doesn't support thumb2.

By the way, we don't track bugs mailed to the gcc-bugs mailing list. 
GCC bugs should be filed into bugzilla, or ask a question on the 
gcc-help mailing list.
