Hi,
4c2ad1
4c2ad1
for Fortran it fixes displaying normal strings also in frames/backtraces:
4c2ad1
4c2ad1
(gdb) frame
4c2ad1
->
4c2ad1
4c2ad1
The patch is simple and I do not see why it should not be this way.
4c2ad1
4c2ad1
For C/C++ TYPE_CODE_STRING is not used.  I am not aware of Pascal but that
4c2ad1
language is currently not really much supported in GDB anyway.

This was a part of my archer/jankratochvil/vla branch but it is not a part of
4c2ad1
the Intel VLA patchset as it in fact is completely unrelated to "VLA".

4c2ad1
No regressions on {x86_64,x86_64-m32,i686}-fedora22pre-linux-gnu.
