--- Comment #5 from Iain Buclaw <ibuclaw at gdcproject.org> ---
What might be useful is to debug gdb here to determine at what point does gdb
give up attempting to read the debug information for the function.

- Is it DW_AT_MIPS_linkage_name that throws it off?
- Is it because DW_AT_name doesn't match the name of the function?
- What is DW_AT_pure doing there?

Whatever it is, it's not putting two and two together.
