Hi,
The generic ELF core handling functions in core-regset.c use gregset_t
and fpregset_t types to access registers. Linux systems use elf_gregset_t
and elf_fpregset_t, though. They have different sizes and layout. While
host-specific files take this into account, core-regset.c does not. As a
result it rejects registers from cores complaining of the size of the area
being incorrect.
The following is a small update I successfully use. I propose it for an
inclusion. Alternatively, a new Linux-specific file might be created, but
that might unnecessarily complicate maintenance -- only type names differ
but files would have to be kept in sync forever.
