Call order from ofd2000 for asm modules

I am trying to get a call order from .asm and ,c files using ofd2000 but am having trouble getting details from a .asm file calling a .c function.

Our compiler options are

SET C2000_C_OPTION=

REM Assembler options
SET C2000_C_OPTION=%C2000_C_OPTION% --cdebug_asm_data
SET C2000_C_OPTION=%C2000_C_OPTION% --cross_reference
SET C2000_C_OPTION=%C2000_C_OPTION% --output_all_syms

REM Compiler options
SET C2000_C_OPTION=%C2000_C_OPTION% --silicon_version=28
SET C2000_C_OPTION=%C2000_C_OPTION% --float_support=fpu32
SET C2000_C_OPTION=%C2000_C_OPTION% --large_memory_model
SET C2000_C_OPTION=%C2000_C_OPTION% --unified_memory
SET C2000_C_OPTION=%C2000_C_OPTION% --opt_level=off
SET C2000_C_OPTION=%C2000_C_OPTION% --symdebug:dwarf
SET C2000_C_OPTION=%C2000_C_OPTION% --obj_directory=obj_dir
SET C2000_C_OPTION=%C2000_C_OPTION% --gen_func_subsections=on

REM Linker options
SET C2000_C_OPTION=%C2000_C_OPTION% --run_linker
SET C2000_C_OPTION=%C2000_C_OPTION% --warn_sections
SET C2000_C_OPTION=%C2000_C_OPTION% --disable_auto_rts
SET C2000_C_OPTION=%C2000_C_OPTION% --mapfile_contents=all
SET C2000_C_OPTION=%C2000_C_OPTION% --rom_model

I am using the command

ofd2000-gx --obj_display=none

I notice that the XML output contains

• DW_TAG_compile_unit - indicates the .asm or .c filename
• DW_TAG_subprogram - indicates a function within the .asm or .c file
• DW_TAG_TI_reserved_3 - indicates a called function from that defined by DW_TAG_subprogram

I have the following

• Math.h
  • FLOAT32 Math__Divide( IN FLOAT32 Dividend, IN FLOAT32 Divisor);
• Math.asm
  •         .def   _Math__Divide
  •         .ref    _MyCalledCFunction
  •         .sect ".text:_Math__Divide"
  •         .clink
  • _Math__Divide:
  •         ; some assembler code
  •         LCR _MyCalledCFunction
  •         LRETR
• MyOuterC.c
  
  • void Outer()
  • {
  •     FLOAT32 a = Math__Divide(10, 2);
  • }
• MyCalledC.h
  
  • void MyCalledCFunction(void);

In the ofd2000 XML output I can see

• DW_TAG_compile_unit - <string>Math.asm</string>
• DW_TAG_subprogram - no tag at all
• DW_TAG_TI_reserved_3 - <string>_MyCalledCFunction</string>

The trouble is that as there is no DW_TAG_subprogram I don't know the name of the asm function (should be _MathDivide) that is calling MyCalledCFunction.

Am I doing something wrong with the compiler options, or the ofd2000 command line or is there some other reason why the tag is missing for the assembler routine?

Thanks
