--- Comment #3 from Thomas Preud'homme <thopre01 at gcc dot gnu.org> --- (In reply to prathamesh3492 from comment #2) > Hi Thomas, > I am trying to cross-build for cortex-m4 to reproduce the issue locally. > Could you please share the configure opts you used ? > > Thanks, > Prathamesh 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!
