Hi Prathamesh,

Only --target=arm-none-eabi is necessary to reproduce as long as you pass
-mcpu=cortex-m7 -mthumb on the command line.

Here's what I used to reproduce:

$SRC/configure --prefix=$PWD/../install --target=arm-none-eabi
make all-gcc
make install-gcc
export PATH=$PWD/../install:$PATH
arm-none-eabi-gcc -S -O2 -Wuninitialized -mcpu=cortex-m7 -mthumb
$SRC/gcc/testsuite/gcc.dg/uninit-pred-8_a.c

Thanks for working on this!
