Hi Prathamesh,
I saw it starting XPASS on arm-none-eabi in test now:

spawn /.../gcc/xgcc -B/.../gcc/ /.../gcc/gcc/testsuite/gcc.dg/uninit-pred-8_a.c
-fno-diagnostics-show-caret -fdiagnostics-color=never -Wuninitialized -O2 -S -o
uninit-pred-8_a.s

/.../gcc/gcc/testsuite/gcc.dg/uninit-pred-8_a.c:43:7: warning: 'v' may be used
uninitialized in this function [-Wmaybe-uninitialized]
output is:
