commit b80c3053162ec5533e120ee4e4ed30296d4c5fb2

Make host_address_to_string/gdb_print_host_address cast parameter to 'void *'
Fixes a set of errors like:
../../src/gdb/symfile-debug.c: In function â??int debug_qf_map_symtabs_matching_filename(objfile*, const char*, const char*, int (*)(symtab*, void*), void*)â??:
../../src/gdb/symfile-debug.c:137:39: error: invalid conversion from â??int (*)(symtab*, void*)â?? to â??const void*â?? [-fpermissive]
host_address_to_string (callback),
^
Note this has to work with data and function pointers. In C++11 we
may perhaps do something a bit safer, but we're not there yet, and I
don't think it really matters. For now just always do a simple
C-style cast in host_address_to_string itself. No point in adding a
void * cast to each and every caller.
gdb/ChangeLog:
2015-10-27 Pedro Alves <palves@redhat.com>
* common/print-utils.c (host_address_to_string): Rename to ...
(host_address_to_string_1): ... this.
* common/print-utils.h (host_address_to_string): Reimplement as
wrapper around host_address_to_string_1.
* utils.c (gdb_print_host_address): Rename to ...
(gdb_print_host_address_1): ... this.
* utils.h (gdb_print_host_address): Reimplement as wrapper macro
around host_address_to_string_1.
