Modified Files:
        src/doc: HACKS

Log Message:
Add note about lib/libc/softfloat/ hack for arm.

  Gcc has a bug in tree optimization. For adddf3, -INF + -INF returns 0 without
  -fno-tree-vrp. Debugging with -fdump-tree-all shows that
  softfloat.c.021t.cleanup_cfg is ok but softfloat.c.023t.ssa is broken.
