I'm using the ecosSWtools-990319 mips-tx39-elf
toolset.

If I try and disassemble an object file compiled from
a C source file (using objdump -d) the first function
comes out as a hexdump e.g.

[root@xxxx]# mips-tx39-elf-gcc -O2 -c misc1.c
[root@xxxx]# mips-tx39-elf-objdump -d misc1.o

misc1.o:     file format elf32-bigmips

Disassembly of section .text:

etc...


Is this a bug somewhere or am I not driving the tools
correctly ?

Thanks
