Hi, The issue files in PR 57683 include lra-constraints.o, lra-eliminations.o and tree-switch-conversion.o.
Jeff had fixed them in trunk (r197467 and r198999): http://gcc.gnu.org/ml/gcc-patches/2013-05/msg00957.html http://gcc.gnu.org/ml/gcc-patches/2013-04/msg00211.html Can we backport the two patches to fix the parallel build issues in 4.8? Thanks! -Zhenqiang
