--- Comment #10 from Richard Biener <rguenth at gcc dot gnu.org> --- (In reply to Richard Earnshaw from comment #7) > Options to reproduce on arm-none-eabi: > > -O3 -mcpu=cortex-a9 -mfpu=neon-fp16 -mfloat-abi=hard -o - vect.c -S > -fdump-tree-all-details Can you create a testcase suitable to be put in gcc.target/arm/ with the required dg- stuff? Alternatively it would fit in gcc.dg/vect/costmodel/ but there's no arm specific directory there.
