Subject: (inf_ptrace_target): Move async_terminal target methods here from
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=39882e987ed506db43704119136e8065d8640b05;p=thirdparty%2Fbinutils-gdb.git

(inf_ptrace_target): Move async_terminal target methods here from
init_exec_ops.  Add async methods.
(inf_ptrace_async): New function (was old standard_async).
