This needs further investigation, but for now we can get the tested sources into the poky gcc harness Signed-off-by: Koen Kooi <k-kooi@ti.com>

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