     1.4 +Fix building gfortran for ARM.
     1.5 +http://gcc.gnu.org/ml/gcc-patches/2007-05/msg01010.html
     1.6 +----
     1.7 +
     1.8 +The patch below fixes a crash building libgfortran on arm-linux-gnueabi.
     1.9 +
    1.10 +This target doesn't really have a 128-bit integer type, however it does use 
    1.11 +TImode to represent the return value of certain special ABI defined library 
    1.12 +functions. This results in type_for_size(TImode) being called.
    1.13 +
    1.14 +Because TImode deosn't correspond to any gfortran integer kind 
    1.15 +gfc_type_for_size returns NULL and we segfault shortly after.
    1.16 +
    1.17 +The patch below fixes this by making gfc_type_for_size handle TImode in the 
    1.18 +same way as the C frontend.
    1.19 +
    1.20 +Tested on x86_64-linux and arm-linux-gnueabi.
    1.21 +Applied to trunk.
