Fixed void* vs int* overload issue (PR C++/10343).
2010-10-14 Sami Wagiaalla <swagiaal@redhat.com>
* gdbtypes.h: Create BASE_PTR_CONVERSION_BADNESS.
* gdbtypes.c (rank_one_type): Move type comparison code out of here
to...
(types_equal): ...here. And changed it as follows:
Outside of typedefs type must be of the same TYPE_CODE.
When compairing two pointers or references they are equal if their
targets are equal.
Correct pointer conversions.
2010-10-14 Sami Wagiaalla <swagiaal@redhat.com>
* gdb.cp/converts.cc: New test program.
* gdb.cp/converts.exp: New test.
* gdb.cp/overload.exp: Added test for void* vs int*.
* gdb.cp/overload.exp: Ditto.
* gdb.cp/oranking.exp: Removed related kfail.
