------- Comment #8 from raj dot khem at gmail dot com 2010-04-30 04:55 ------- below is the linker command that reports liking error.
/scratch/oe/efika/cross/ppc603e/lib/gcc/powerpc-oe-linux/4.5.0/crtend.o: In function `__do_global_ctors_aux': crtstuff.c:(.text+0xc): undefined reference to `_savegpr_31' collect2: ld returned 1 exit status as we can see the failure is seen in crtend.o and in the linking order libgcc is specified before crtend.o therefore it does not pick the required object from libgcc.a if I add -lgcc after crtend.o then it links successfully. /scratch/oe/efika/cross/ppc603e/bin/powerpc-oe-linux-gcc -nostdlib -nostartfiles -o /scratch/oe/efika/work/ppc603e-oe-linux/eglibc-2.11-r10.4/build-powerpc-oe-linux/posix/getconf -Wl,-dynamic-linker=/lib/ld.so.1 -Wl,-z,combreloc -Wl,-z,relro -Wl,--hash-style=both /scratch/oe/efika/work/ppc603e-oe-linux/eglibc-2.11-r10.4/build-powerpc-oe-linux/csu/crt1.o /scratch/oe/efika/work/ppc603e-oe-linux/eglibc-2.11-r10.4/build-powerpc-oe-linux/csu/crti.o `/scratch/oe/efika/cross/ppc603e/bin/powerpc-oe-linux-gcc -mcpu=603e -mhard-float --print-file-name=crtbegin.o` /scratch/oe/efika/work/ppc603e-oe-linux/eglibc-2.11-r10.4/build-powerpc-oe-linux/posix/getconf.o -Wl,-rpath-link=/scratch/oe/efika/work/ppc603e-oe-linux/eglibc-2.11-r10.4/build-powerpc-oe-linux:/scratch/oe/efika/work/ppc603e-oe-linux/eglibc-2.11-r10.4/build-powerpc-oe-linux/math:/scratch/oe/efika/work/ppc603e-oe-linux/eglibc-2.11-r10.4/build-powerpc-oe-linux/elf:/scratch/oe/efika/work/ppc603e-oe-linux/eglibc-2.11-r10.4/build-powerpc-oe-linux/dlfcn:/scratch/oe/efika/work/ppc603e-oe-linux/eglibc-2.11-r10.4/build-powerpc-oe-linux/nss:/scratch/oe/efika/work/ppc603e-oe-linux/eglibc-2.11-r10.4/build-powerpc-oe-linux/nis:/scratch/oe/efika/work/ppc603e-oe-linux/eglibc-2.11-r10.4/build-powerpc-oe-linux/rt:/scratch/oe/efika/work/ppc603e-oe-linux/eglibc-2.11-r10.4/build-powerpc-oe-linux/resolv:/scratch/oe/efika/work/ppc603e-oe-linux/eglibc-2.11-r10.4/build-powerpc-oe-linux/crypt:/scratch/oe/efika/work/ppc603e-oe-linux/eglibc-2.11-r10.4/build-powerpc-oe-linux/nptl /scratch/oe/efika/work/ppc603e-oe-linux/eglibc-2.11-r10.4/build-powerpc-oe-linux/libc.so.6 /scratch/oe/efika/work/ppc603e-oe-linux/eglibc-2.11-r10.4/build-powerpc-oe-linux/libc_nonshared.a -lgcc `/scratch/oe/efika/cross/ppc603e/bin/powerpc-oe-linux-gcc -mcpu=603e -mhard-float --print-file-name=crtend.o` /scratch/oe/efika/work/ppc603e-oe-linux/eglibc-2.11-r10.4/build-powerpc-oe-linux/csu/crtn.o -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43810
