Hi Nick,

I'm using version 4.8.2 of arm-none-eabi-gcc

Here's an example of the error that I am seeing:

%> arm-none-eabi-gcc --specs=rdimon.specs CQ24877.obj -o RV30.out
/usr/lib/gcc/arm-none-eabi/4.8.2/../../../arm-none-eabi/bin/ld: error:
CQ24877.obj uses VFP register arguments, RV30.out does not
/usr/lib/gcc/arm-none-eabi/4.8.2/../../../arm-none-eabi/bin/ld: warning:
CQ24877.obj uses 2-byte wchar_t yet the output is to use 4-byte wchar_t; use of
wchar_t values across objects may fail
/usr/lib/gcc/arm-none-eabi/4.8.2/../../../arm-none-eabi/bin/ld: failed to merge
target specific data of file CQ24877.obj

Which version of the binutils did the patch go into?

Thanks,
Todd

--- Comment #1 from Nick Clifton <nickc at redhat dot com> --- Hi Todd,

  Which version of the binutils are you using ?

  It looks like a patch went in a couple of years ago that was supposed to
handle this:

  2014-12-25  Thomas Preud'homme  <address@hidden>

        * elf32-arm.c (elf32_arm_merge_eabi_attributes): Handle new
        Tag_ABI_VFP_args value and replace hardcoded values by enum values.
        (elf32_arm_post_process_headers): Set e_flags in ELF header as hard
        float only when Tag_ABI_VFP_args is 1, using new enum value
        AEABI_VFP_args_vfp to check that.

  If the problem does exist with the latest binutils sources, then please
  could you preoide a full test case so that we can reproduce the problem
  locally.  (ie linker command line + object files).

Cheers
  Nick
