Use previous count when 'x' command is repeated
About the 'x' command, the manual says: If you use <RET> to repeat the 'x' command, the repeat count N is used again; the other arguments default as for successive uses of 'x'. However, PR gdb/22619 points out that this does not work. This patch fixes the problem. ChangeLog 2018-05-04 Tom Tromey <tom@tromey.com> PR gdb/22619: * printcmd.c (last_count): New global. (x_command): Use saved count when repeating. testsuite/ChangeLog 2018-05-04 Tom Tromey <tom@tromey.com> PR gdb/22619: * gdb.base/long_long.exp (gdb_test_long_long): Add test for repeat behavior.
