Bug #: 53859
Summary: ICE when calculate insn latency for armv7e-m arch in
O2 level
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: zhuolin.liu@arm.com
I cross built a compiler from recent trunk code for arm-none-eabi target. When
use this compiler to compile following code for armv7e-m arch, I got an
internal compiler error.
My code is simple as:
void bar (int,int,char* ,int);
void foo (char c)
{
bar (1,2,&c,3 );
}
ICE is triggered by command:
build@sha-pdsh-build:$ arm-none-eabi-gcc -mthumb -march=armv7e-m -O2 -c test.c
test.c: In function 'foo':
test.c:13:1: internal compiler error: Segmentation fault
}
^
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
After I change my code to:
void bar (int,int,char* ,int);
static void foo (char c)
{
bar (1,2,&c,3 );
}
This ICE is gone.
