------- Comment #4 from mikpe at it dot uu dot se 2010-07-24 19:36 ------- Attempting to bootstrap 4.5.1-RC on powerpc-linux with --enable-target-optspace fails near the end of stage1 while configuring libgomp:
configure:3658: checking for C compiler default output file name configure:3680: /home/mikpe/objdir/./gcc/xgcc -B/home/mikpe/objdir/./gcc/ -B/tmp/install/powerpc-unknown-linux-gnu/bin/ -B/tmp/install/powerpc-unknown-linux-gnu/lib/ -isystem /tmp/install/powerpc-unknown-linux-gnu/include -isystem /tmp/install/powerpc-unknown-linux-gnu/sys-include -g -Os conftest.c >&5 /home/mikpe/objdir/./gcc/crtend.o: In function `__do_global_ctors_aux': crtstuff.c:(.text+0xc): undefined reference to `_savegpr_31' collect2: ld returned 1 exit status libgcc.a was built and does define _savegpr_31, and libgcc_s.so is the expected linker script, and both files are available in the build directory. So yes, --enable-target-optspace appears broken. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45053
