Compilation error when using -Os

Bug Description

Arm GNU Toolchain Version: 11.2-2022.02
Binary package

When I compile with -Os I get an error stating "/tmp/ccRelRdU.s:35 Error: syntax error -- `vcvtne.s32.f32 s15,s0'". Full compilation command to reproduce is "arm-none-eabi-gcc -Os -mthumb -mcpu=cortex-m55 -mlittle-endian -mfpu=fpv5-d16 -mfloat-abi=hard -c test.c -o test.o" where test.c has the following code.

int test_function(float value)
  int ret_val = 10;
  if (value != 0.0)
    ret_val = (int) value;
  return ret_val;

If I simply remove the "-Os" from the compilation command this error goes away.
