3The patch below fixes a crash building libgfortran on arm-linux-gnueabi.
4
5This target doesn't really have a 128-bit integer type, however it does use
6TImode to represent the return value of certain special ABI defined library
7functions. This results in type_for_size(TImode) being called.
8
9Because TImode deosn't correspond to any gfortran integer kind
10gfc_type_for_size returns NULL and we segfault shortly after.
11
12The patch below fixes this by making gfc_type_for_size handle TImode in the
13same way as the C frontend.
14
15Tested on x86_64-linux and arm-linux-gnueabi.
16Applied to trunk.
