     1 Fix building gfortran for ARM.

     2 http://gcc.gnu.org/ml/gcc-patches/2007-05/msg01010.html

     3 ----

     5 The patch below fixes a crash building libgfortran on arm-linux-gnueabi.

     6 

     7 This target doesn't really have a 128-bit integer type, however it does use 

     8 TImode to represent the return value of certain special ABI defined library 

     9 functions. This results in type_for_size(TImode) being called.

    10 

    11 Because TImode deosn't correspond to any gfortran integer kind 

    12 gfc_type_for_size returns NULL and we segfault shortly after.

    13 

    14 The patch below fixes this by making gfc_type_for_size handle TImode in the 

    15 same way as the C frontend.

    16 

    17 Tested on x86_64-linux and arm-linux-gnueabi.

    18 Applied to trunk.
