Dwarf specs? Help required with unknown dwarf1 attribute

• Messages sorted by:[ date ][ thread ][ subject ][ author ]

We are using arm-elf-gcc to compile/link code with eCos using '-gdwarf'
targetted at the ARM7TDMI. We are having trouble using a utility that converts
the image to another download format with side files for debugging information.
According to the analysis there is an uknown attribute in the dwarf data:

[quote]
The dwarf file seems to contain an unknown attribute (0x00cf)
which is not a standard attribute for dwarf.
The location of this unknown attribute is 0x8682th 2 byte
from the beginning of the file. Below is the dump of the
dwarf file near the unknown attribute.
(For your information, the .debug section start from 0x85dc.)

   :                :              :           :                    :
   :                :              :           :                    :

00008680 : 00 00 cf 00 00 00 05 00 12 00 cf 00 00 00 38 00    ..............8.
                 ^^^^^

Can anyone help with the interpretation of this attribute?

More generally, where can I find definitions of the dwarf and dwarf2 formats
that can be generated with arm-elf-gcc, to help with work on our conversion
utility?

Many thanks

Mick
