| 1 | The patch below fixes a crash building libgfortran on arm-linux-gnueabi. | ||
| 2 | |||
| 3 | This target doesn't really have a 128-bit integer type, however it does use | ||
| 4 | TImode to represent the return value of certain special ABI defined library | ||
| 5 | functions. This results in type_for_size(TImode) being called. | ||
| 6 | |||
| 7 | Because TImode deosn't correspond to any gfortran integer kind | ||
| 8 | gfc_type_for_size returns NULL and we segfault shortly after. | ||
| 9 | |||
| 10 | The patch below fixes this by making gfc_type_for_size handle TImode in the | ||
| 11 | same way as the C frontend. | ||
| 12 | |||
| 13 | Tested on x86_64-linux and arm-linux-gnueabi. | ||
| 14 | Applied to trunk. | ||
