Hello,
for the test case gcc.dg/uninit-13.c:
/* { dg-do compile } */
/* { dg-options "-O -Wuninitialized" } */
typedef _Complex float C;
C foo()
{
C f;
__imag__ f = 0; /* { dg-warning "is used" "unconditional" } */
return f;
}
I have the following failure on arm-rtems:
spawn -ignore SIGHUP /scratch/git-rtems-testing/gcc/b-arm-gcc/gcc/xgcc

output is:

FAIL: gcc.dg/uninit-13.c unconditional (test for warnings, line 8)
FAIL: gcc.dg/uninit-13.c (test for excess errors)
Fails also on arm-eabi:
http://gcc.gnu.org/ml/gcc-testresults/2014-02/msg00200.html
On the other hand this test seems to pass on armv7l-unknown-linux-gnueabihf:
http://gcc.gnu.org/ml/gcc-testresults/2014-02/msg00280.html
Does anyone know what is wrong here?
