GDB with Hitachi Linker output

GDB with Hitachi Linker output

[Andrew Philp]

Hello,
with regard to your earlier email correspondence which I found at
redhat.com, could you please update me as to what the latest is regarding
using GDB and Hitachi linker output. I'm successfully remote debugging a H8
target and just need to load the symbol table to get source level debugging
working.

I've been looking for a object file converter utility, which out much luck.

thanks for helping
Andrew


>> original email trail.........
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.Toshi> > >>>>>
