Bug #: 50949
Summary: ICE on armhf with neon code
Classification: Unclassified
Product: gcc
Version: 4.6.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: konstantinos.margaritis@linaro.org
Host: arm-linux-gnueabihf
Target: arm-linux-gnueabihf
Build: arm-linux-gnueabihf
Created attachment 25680
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25680
minimal testcase produced using delta tool from source (propriatery driver
including NEON code)
(Note: this is a different ICE than #PR50948, but produced from the
same file as the previous, in fact it's produced from the same
function, albeit with a small modification).
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 (which is different than the one in
#PR50948), that produces the exact ICE. The testcase is attached. Here
is the message and the cmd line used:
$ gcc -O -mfpu=neon matrix2-min.i
matrix2-min.i: In function ‘matrixTranspose’:
matrix2-min.i:38:5: error: insn does not satisfy its constraints:
(insn 41 16 17 2 (set (mem/c/i:XI (pre_dec:SI (reg/f:SI 5 r5 [145]))
[0 S64 A64])
(reg:XI 111 d24)) matrix2-min.i:21 753 {*neon_movxi}
(expr_list:REG_INC (reg/f:SI 5 r5 [145])
(nil)))
matrix2-min.i:38:5: internal compiler error: in
reload_cse_simplify_operands, at postreload.c:403
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/ccpGsI3S.out file, please attach
this to your bugreport.
This ICE is not reproducible on gcc-4.6 on oneiric/armel.
This bug has also been filed to the Debian BTS:

arm-linux-gnueabihf isn't a configuration supported by FSF GCC; if this is
vendor distribution you need to contact your vendor. Alternatively you need to
show how to produce this on the FSF sources.

This is the full cmd line used:
gcc -g -O -mfpu=neon -mfloat-abi=hard -march=armv7-a -mthumb -fpermissive -c
matrix.i
This is the actual gcc revision used in the Debian package: 20111028 (r180603).
