I added a field to struct basic_block_def in basic-block.h of type struct pointer_set_t.
Now when I try to rebuild GCC build fails with error: libbackend.a(gtype-desc.o): In function `gt_pch_nx_basic_block_def': /scratch/dweeratu/gcc/build/gcc/gtype-desc.c:2472: undefined reference to `gt_pch_nx_pointer_set_t' /scratch/dweeratu/gcc/build/gcc/gtype-desc.c:2473: undefined reference to `gt_pch_nx_pointer_set_t' libbackend.a(gtype-desc.o): In function `gt_ggc_mx_basic_block_def': /scratch/dweeratu/gcc/build/gcc/gtype-desc.c:708: undefined reference to `gt_ggc_mx_pointer_set_t' /scratch/dweeratu/gcc/build/gcc/gtype-desc.c:709: undefined reference to `gt_ggc_mx_pointer_set_t' collect2: ld returned 1 exit status It looks as if some auto generated files are not been regenerated properly. This happens even if I completely redo the build. How can this be fixed? thanks, -- dasarath
