Member Function Documentation

◆ CalculateTrapHandlerSymbolNames()

void PlatformLinux::CalculateTrapHandlerSymbolNames ( )

overridevirtual

Ask the Platform subclass to fill in the list of trap handler names.

For most Unix user process environments, this will be a single function name, _sigtramp. More specialized environments may have additional handler names. The unwinder code needs to know when a trap handler is on the stack because the unwind rules for the frame that caused the trap are different.

The base class Platform ivar m_trap_handlers should be updated by the Platform subclass when this method is called. If there are no predefined trap handlers, this method may be a no-op.

Implements lldb_private::Platform.

Definition at line 202 of file PlatformLinux.cpp.

References lldb_private::Platform::m_trap_handlers.

◆ CanDebugProcess()

bool PlatformLinux::CanDebugProcess ( )

overridevirtual

Not all platforms will support debugging a process by spawning somehow halted for a debugger (specified using the "eLaunchFlagDebug" launch flag) and then attaching.

If your platform doesn't support this, override this function and return false.

Try to get a specific unwind plan for a named trap handler.

The default is not to have specific unwind plans for trap handlers.

Parameters

[in]	triple	Triple of the current target.
[in]	name	Name of the trap handler function.

Returns: A specific unwind plan for that trap handler, or an empty shared pointer. The latter means there is no specific plan, unwind as normal.
