Summary: ICE [arm] immed_double_const at emit-rtl.c (-mfpu=neon
-g -O1)
Product: gcc
Version: 4.5.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: juha.kallioinen@nokia.com
Created attachment 23707
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=23707
pre-processed source
When compiling the attached pre-processed source for arm (-march=armv7-a
-mtune=cortex-a8) and using options -mfpu=neon -g -O1 I get an ICE.
kaltsi@kaltsnatty:~/tmp/ice$ arm-linux-gnueabi-gcc-4.5 -mfpu=neon -O1 -g -c
emit-rtl-ice.i
optimized.c: In function ‘move_16bit_to_32bit’:
optimized.c:4:6: internal compiler error: in immed_double_const, at
emit-rtl.c:552
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.5/README.Bugs> for instructions.
This does not happen if I leave the -g option out.

--- Comment #1 from Havard Graff <havard.graff at gmail dot com> 2011-12-01 19:58:11 UTC ---
I have some additional info related to this bug:
If I compile the following:
#include "arm_neon.h"
#include "stdlib.h"
int main ()
{
float r [] = {0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f};
float32x4x2_t d;
d = vld2q_f32 (r);
vst2q_f32 (r, d);
return 0;
}
using: arm-linux-androideabi-gcc test.c -mfloat-abi=softfp -mfpu=neon -g -O1
I get:
test.c: In function 'main':
test.c:4:5: internal compiler error: in immed_double_const, at emit-rtl.c:550
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
However, if I comment out vst2q_f32 (r, d);, the problem goes away. Also by not
using -g or -O1.
$ arm-linux-androideabi-gcc -v
Using built-in specs.
