[PATCH/RFA] OpenBSD/powerpc support
Mark Kettenis

Sun Apr 18 17:17:00 GMT 2004
Kevin,
The attached patch adds support for OpenBSD/powerpc (OpenBSD/macppc)
to GDB. This stuff uses the new core file support, and to support
this, I've invented some new functions:
* ppc_supply_gregset()
* ppc_collect_gregset()
* ppc_supply_fpregset()
* ppc_collect_fpregset()
These functions would be useful to other POWER and PowerPC targets
too. The idea is to provide a `struct ppc_reg_offsets' initialized to
describe the layout of the registers in the relevant core file
sections.
For now I've added these functions to ppcobsd-tdep.c (and the
definition of `struct pcc_reg_offsets' to ppcobsd-tdep.h. But they
should probably be moved to rs6000-tdep.c (and ppc-tdep.h).
OK to check this in?
Mark
