yes, I know, I just checked that behavior is the same as before. With these flags -mthumb -mcpu=cortex-m4 -mfpu=fpv4-sp-d16 -mfloat-abi=hard
I got error from linker: /home/midnight/rtems/toolchain/5/lib/gcc/arm-rtems5/7.4.1/../../../../arm-rtems5/bin/ld: error: o-optimize/test.exe uses VFP register arguments, / home/midnight/workspace/rtems/build/arm-rtems5/stm32l4/lib/librtemsbsp.a(bspfatal-default.o) does not /home/midnight/rtems/toolchain/5/lib/gcc/arm-rtems5/7.4.1/../../../../arm-rtems5/bin/ld: failed to merge target specific data of file /home/midnig ht/workspace/rtems/build/arm-rtems5/stm32l4/lib/librtemsbsp.a(bspfatal-default.o) Currently I'm trying to figure out what is a problem.
