using the FPU on Cortex A9

Hi,

Please help me to update my project for hardware floating point.

my make file is like this:

//======================================

SOCEDS_ROOT ?= $(SOCEDS_DEST_ROOT)

HWLIBS_ROOT = $(SOCEDS_ROOT)/ip/altera/hps/altera_hps/hwlib

HWLIBS_SRC :=

EXAMPLE_SRC := hello.c io.c

C_SRC := $(EXAMPLE_SRC) $(HWLIBS_SRC) alt_fpga_manager.c alt_bridge_manager.c alt_clock_manager.c i2c.c cascade_header.c

LINKER_SCRIPT := cycloneV-dk-ram-modified.ld

MULTILIBFLAGS := -mcpu=cortex-a9 -mfloat-abi=softfp -mfpu=neon-fp16

CFLAGS := -g -O0 -Wall -Werror -std=c99 $(MULTILIBFLAGS) -I$(HWLIBS_ROOT)/include

LDFLAGS := -T$(LINKER_SCRIPT) $(MULTILIBFLAGS)

CROSS_COMPILE := arm-altera-eabi-

CC := $(CROSS_COMPILE)gcc

LD := $(CROSS_COMPILE)g++

OC := $(CROSS_COMPILE)objcopy

MKIMAGE := mkimage

RM := rm -rf

CP := cp -f

ELF ?= $(basename $(firstword $(C_SRC))).axf

OBJ := $(patsubst %.c,%.o,$(C_SRC))

BIN = $(basename $(firstword $(C_SRC))).bin

IMG = $(basename $(firstword $(C_SRC)))-mkimage.bin

.PHONY: all

all: $(BIN) $(ELF) $(IMG) $(SPL)

.PHONY: clean

clean:

$(RM) $(ELF) $(HWLIBS_SRC) $(OBJ) $(BIN) $(IMG)

%.c: $(HWLIBS_ROOT)/src/hwmgr/%.c

$(CP) $< $@

$(OBJ): %.o: %.c Makefile

$(CC) $(CFLAGS) -c $< -o $@

$(ELF): $(OBJ)

$(LD) $(LDFLAGS) $(OBJ) -o $@

$(BIN): $(ELF)

$(OC) -O binary $(ELF) $(BIN)

$(IMG): $(BIN)

$(MKIMAGE) -A arm -T standalone -C none -a 0x100040 -e 0 -n "baremetal image" -d $(BIN) $(IMG)

//======================================

where I need to change ??

I have tried with hard in place of softfp and it gives me error in build project

error is like this:

//=================

error: hello.o uses VFP register arguments, hello.axf does not

//=================

please help me as soon as possible

Thanks in advance.
