◆ GetSoftwareBreakpointPCOffset()

size_t lldb_private::NativeProcessWindows::GetSoftwareBreakpointPCOffset ( )
overrideprotectedvirtual

Return the offset of the PC relative to the software breakpoint that was hit.

If an architecture (e.g. arm) reports breakpoint hits before incrementing the PC, this offset will be 0. If an architecture (e.g. intel) reports breakpoints hits after incrementing the PC, this offset will be the size of the breakpoint opcode.
