I found Jie has committed a patch
"http://sourceware.org/ml/binutils/2010-05/msg00083.html". I am using
the newest binary utils and encounted the following ASSERT in
arm_elf32.c:
+             if (out_attr[i].i == 0)
+               {
+                 BFD_ASSERT (out_attr[Tag_ABI_HardFP_use].i == 0);

My compiling options are as below,
ASM_FLAGS              :=                                                      \
                        -gdwarf-2                                             \
                        -mfpu=vfp                                             \
                        -mfloat-abi=softfp                                    \

                        $(ASM_FLAGS)                                          \
                        -O3     -Wno-all                                      \

                        -fno-rtti                                             \

                         --gc-sections -nostdlib                              \
                         -L ../stdlib                                         \
                         -Wl,--as-needed                                      \
                         -Wl,-no-enum-size-warning                            \
                         --cref                                               \

ARFLAGS                :=
        \
                             rcs

Can anyone give me any tip about why the assert is triggered?
