Re: GDB with Hitachi Linker output?

[Toshiyasu Morita <tm@netcom.com>]

The SRCONV utility is actually pretty broken, through no fault of Cygnus.

We ran into the problem three years ago that SRCONV-emitted files caused the 
Hitachi in-circuit emulator to crash. After much consultation with both 
sides, we determined that:

1) The Hitachi SYSROF spec only describes the output of the data from the 
compiler/linker, and do not specify implicit ordering dependencies, and 

2) linker/debugger are fragile and do not emit  proper error messages 
when a certain section is out of order.

Therefore, it was impossible to debug the problem and we gave up on SRCONV.
