[patch 2/5] allow pending tracepoint
- From: Yao Qi <yao at codesourcery dot com>

- Subject: [patch 2/5] allow pending tracepoint
- References: <4EC20E2E.6010402@codesourcery.com>
Existing breakpoint infrastructure in gdb makes easier to do pending
tracepoint. We just create right type (tracepoint) for pending state.
Note that we don't check/validate SALs for pending fast tracepoint,
because inferior may not be ready to access at that moment.

gdb/
* breakpoint.c (create_breakpoint): Produce query message according to
breakpoint's type.
Allocate tracepoint per correct type.
Don't check SALs for pending fast tracepoints.
