Component: c
AssignedTo: unassig...@gcc.gnu.org

minimal testcase produced using delta tool from source (propriatery driver
including NEON code)
When building neon code on armhf -which I cannot attach to its full,
due to licensing reason, unfortunately- I get an ICE. Using delta I
was able to get a minimal testcase that produces the exact ICE. The
testcase is attached. Here is the message and the cmd line used:
$ gcc -O -mfpu=neon matrix-min.i
matrix-min.i: In function ‘matrixTranspose’:
matrix-min.i:10:29: internal compiler error: in immed_double_const, at
emit-rtl.c:550
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.6/README.Bugs> for instructions.
Preprocessed source stored into /tmp/cc3zlt4j.out file, please attach
this to your bugreport.
In fact, the same ICE I get on oneiric gcc with the same testcase.
The bug has also been filed on Debian BTS:
