           Summary: Bootstrap fails in stage1 with GCC 4.6
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: rgue...@gcc.gnu.org
            Target: powerpc64-*-linux


When bootstrapping trunk using a GCC 4.6 (from begin of december) host compiler
using CFLAGS="-O -g" I get the following error when linking cc1 during stage1:


/usr/lib64/gcc/powerpc64-suse-linux/4.6/../../../../powerpc64-suse-linux/bin/ld:
 libbackend.a(cse.o)(.text.unlikely+0x60): sibling call optimization to 
               `.opd' does not allow automatic multiple TOCs; recompile with 
-mminimal-toc or -fno-optimize-sibling-calls, or make `.opd' extern

I don't know if this hints at a generic problem or if this is some intermediate
failure of that particular host compiler version (which of course
bootstrapped just fine at some point).
