Bug #: 52855
Summary: ARM: Internal compiler error: in extract_insn, at
recog.c:2109
Classification: Unclassified
Product: gcc
Version: 4.6.3
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: c
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: mpthompson@gmail.com
Created attachment 27080
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27080
Preprocessed *.i* file that triggers the bug. See command line in description
to trigger bug.
Using GCC 4.6.3 on Debian armhf to create ARMv6+VFP binaries for Raspberry Pi
computer. The compiler differs from the standard Debian Wheezy armhf as the
configured with the options: --with-arch=armv6 --with-float=hard --with-fpu=vfp
The file that triggers the error mg.c from a build of the Perl package. Test
files and information to reproduce the error given below.

--- Comment #1 from Mike Thompson <mpthompson at gmail dot com> 2012-04-04 15:29:47 UTC ---
This bug can be reproduced using the standard gcc 4.6.3 packages that is part
of the Debian wheezy armhf port. The command line to trigger the bug is:
gcc -DPERL_CORE -c -D_REENTRANT -D_GNU_SOURCE -DDEBIAN -D_FORTIFY_SOURCE=2 -g
-O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security
-Werror=format-security -fno-strict-aliasing -pipe -I/usr/local/include
-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -O2 -g -Wall -W -Wextra
-Wdeclaration-after-statement -Wendif-labels -Wc++-compat -Wwrite-strings -marm
-march=armv6 -mfpu=vfp -o cccPDUUP.o cccPDUUP.
The regular Debian wheezy gcc is configured with the following options:
Configured with: ../src/configure -v --with-pkgversion='Debian 4.6.3-1'
--with-bugurl=file:///usr/share/doc/gcc-4.6/README.Bugs
--enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr

--enable-libstdcxx-debug --enable-libstdcxx-time=yes --enable-plugin
--enable-objc-gc --disable-sjlj-exceptions --with-arch=armv7-a

Confirmed with 4.6.3 and -march=armv6 or higher at -O1 and higher, no other
flags needed. No error with 4.5, 4.7, or 4.8.
The Linaro 4.6 branch does not have the problem either, so whatever they've
added seems to fix it.

The ICE is fixed by the patch for PR50099. See especially
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50099#c6 which shows the same ICE
in Perl as shown here. Therefore I think this is a dup of PR50099.

--- Comment #4 from Steinar Midtskogen <stemidts at cisco dot com> 2012-11-16 09:48:36 UTC ---
I've run into the same bug. The code below reproduces it:
#include <arm_neon.h>
static const __attribute__((aligned(16)))
int16_t c[][2][8] =
{
{ { 0 }, { 0 } }, { { 0 }, { 0 } }, { { 0 }, { 0 } }, { { 0 }, { 0 } },
{ { 0 }, { 0 } }, { { 0 }, { 0 } }, { { 0 }, { 0 } }, { { 0 }, { 0 } }
};
int16x8_t test2(int off)
{
return vld1q_u8((uint8_t*)c[off][0]);
}
int16x8_t test(int off, uint8_t **c)
{
static int8_t m[] = { 1, 2, 3 };
long long cf = m[off];
return vld1q_u8((uint8_t*)c[cf]);
}
Version: 4.6.3
Options: -mapcs-frame -mfloat-abi=softfp -mfpu=neon -flax-vector-conversions
-O1
Changing "long long cf" into "int cf" eliminates the crash.
