Hello,

 The following change fixes this test case failure:

break *0x80020278
Breakpoint 3 at 0x80020278: file /n/bank/raid/macro/src7-mdi/combined/gdb/testsuite/gdb.base/consecutive.c, line 10.
(gdb) PASS: gdb.base/consecutive.exp: set bp, 2nd instr
step

Breakpoint 3, 0xffffffff80020278 in foo () at /n/bank/raid/macro/src7-mdi/combined/gdb/testsuite/gdb.base/consecutive.c:10
10        return a[0] + a[1] + a[2] + a[3] + a[4] + a[5] + a[6];
(gdb) FAIL: gdb.base/consecutive.exp: stopped at bp, 2nd instr (wrong address)
 
This change has been tested natively for mips-unknown-linux-gnu and 
remotely for mipsisa32-sde-elf, using mips-sim-sde32/-EB and 
mips-sim-sde32/-EL as the targets, with no regressions for the former and 
removing the failure for the two latters.

	* ui-out.c (ui_out_field_core_addr): Truncate address to
	TARGET_ADDR_BIT size before printing.


 OK to apply?
