2005-11-07 Kevin Buettner <kevinb@redhat.com>
* frv-linux-tdep.c (frv_linux_sigtrapm_frame_prev_register): Change
type of `valuep' argument to `gdb_byte *'.
* frv-tdep.c (frv_pseudo_register_write): Change type of `buffer'
argument to `gdb_byte *'.
(frv_extract_return_value): Change type of `valbuf' argument to
`gdb_byte *'.
(frv_store_return_value): Likewise.
(frv_frame_prev_register): Change type of `bufferp' argument to
`gdb_byte *'
* solib-frv.c (ext_Elf32_Half, ext_Elf32_Addr, ext_Elf32_Word)
(ext_ptr): Change base type from `unsigned char' to `gdb_byte'. Adjust
calls to extract_unsigned_integer which use struct members declared
with these array types to not try to take the address of those
members.
(fetch_loadmap, frv_current_sos): Change cast in target_read_memory()
calls from `char *' to `gdb_byte *'.
(lm_base): Change base type of `buf' from `char' to `gdb_byte'.
(enable_break2): Change type of `buf' from `char *' to `gdb_byte *'.
Change base type of `addr_buf' from `char' to `gdb_byte'.
(find_canonical_descriptor_in_load_object): Change base type of `buf'
from `char' to `gdb_byte'.
2005-11-07 Paul Gilliam <pgilliam@us.ibm.com
* ppc-sysv-tdep.c (ppc64_sysv_abi_return_value): Copy code from
