* Separated the "expr --unwind-on-error" behavior into two parts, actual ↵Jim Ingham2013-01-151-2/+3
| | | | | | | | | | | | | | | | errors (i.e. crashes) which continue to be controlled by the --unwind-on-error flag, and --ignore-breakpoint which separately controls behavior when a called function hits a breakpoint. For breakpoints, we don't unwind, we either stop, or ignore the breakpoint, which makes more sense. Also make both these behaviors globally settable through "settings set". Also handle the case where a breakpoint command calls code that ends up re-hitting the breakpoint. We were recursing and crashing. Now we just stop without calling the second command. <rdar://problem/12986644> <rdar://problem/9119325> llvm-svn: 172503

* Thread hardening part 3. Now lldb_private::Thread objects have std::weak_ptrGreg Clayton2012-02-211-1/+1
| | | | | | | | | | | | | | | | | objects for the backlink to the lldb_private::Process. The issues we were running into before was someone was holding onto a shared pointer to a lldb_private::Thread for too long, and the lldb_private::Process parent object would get destroyed and the lldb_private::Thread had a "Process &m_process" member which would just treat whatever memory that used to be a Process as a valid Process. This was mostly happening for lldb_private::StackFrame objects that had a member like "Thread &m_thread". So this completes the internal strong/weak changes. Documented the ExecutionContext and ExecutionContextRef classes so that our LLDB developers can understand when and where to use ExecutionContext and ExecutionContextRef objects. llvm-svn: 151009
* Improve the x86_64 return value decoder to handle most structure returns.Jim Ingham2011-12-221-1/+1

* Enhanced the ObjC DynamicCheckerFunction to test for "object responds to ↵Jim Ingham2011-11-011-1/+15
| | | | | | | | | | | | | | selector" as well as "object borked"... Also made the error when the checker fails reflect this fact rather than report a crash at 0x0. Also a little cleanup: - StopInfoMachException had a redundant copy of the description string. - ThreadPlanCallFunction had a redundant copy of the thread, and had a copy of the process that it didn't really need. llvm-svn: 143419
* Added support for generating expressions that haveSean Callanan2010-12-131-1/+2
| | | | | | | | | | | | | | access to the members of the Objective-C self object. The approach we take is to generate the method as a @category on top of the self object, and to pass the "self" pointer to it. (_cmd is currently NULL.) Most changes are in ClangExpressionDeclMap, but the change that adds support to the ABIs to pass _cmd touches a fair amount of code. llvm-svn: 121722

timeouts, and restarting with all threads into a utility function in Process. This required a bunch of renaming. Added a ThreadPlanCallUserExpression that differs from ThreadPlanCallFunction in that it holds onto a shared pointer to its ClangUserExpression so that can't go away before the thread plan is done using it. Fixed the stop message when you hit a breakpoint while running a user expression so it is more obvious what has happened. llvm-svn: 120386
