problem with objcopy IEEE-695 support

[john . robinson]

I have a problem with binutils-2.17
objcopy, and IEEE-695 support.

I am trying to use objcopy to convert
an ELF file from Tasking VX 2.1r1 toolchain for the Infineon c16x into
an IEEE-695 format for use with an earlier Tasking debugger. 

I have downloaded binutils version 2.17,
and built it with --enable-targets=all, using cygwin.

I can run the conversion from ELF to
IEEE, but the resulting file cannot be read by the debugger.  It cannot
be read by objcopy itself, which I find quite odd.  I am not sure
whether to suspect the reading or writing of the file, and I am having
trouble finding much about the file format.  

This is what I see:

C:\DOCUME~1\JROBIN~1\WORKSP~1\myproj\Debug>readelf
-h myproj.elf

C:\DOCUME~1\JROBIN~1\WORKSP~1\myproj\Debug>c:\cygwin\binutils-2.17\binutils\objcopy
-I elf32-little -O ieee myproj.elf myproj_0.abs

C:\DOCUME~1\JROBIN~1\WORKSP~1\myproj\Debug>c:\cygwin\binutils-2.17\binutils\objcopy
-I ieee -O ieee myproj_0.abs myproj_1.abs
/binutils-2.17/binutils/objcopy: myproj_0.abs:
File format not recognized

I suspect this happens with almost any
elf->abs->abs conversion.  When I have attached my example files
the email has been rejected.  If anyone wants my examples files, please
email me.

Thank you
