Classes
struct	lldb_private::trace_intel_pt::PSBBlock
	This struct represents a contiguous section of a trace that starts at a PSB and ends right before the next PSB or the end of the trace. More...
struct	lldb_private::trace_intel_pt::IntelPTThreadContinousExecution
	This struct represents a continuous execution of a thread in a cpu, delimited by a context switch in and out, and a list of Intel PT subtraces that belong to this execution. More...

Namespaces
namespace	lldb_private
	A class that represents a running process on the host machine.

Functions
llvm::Error	lldb_private::trace_intel_pt::DecodeSingleTraceForThread (DecodedThread &decoded_thread, TraceIntelPT &trace_intel_pt, llvm::ArrayRef< uint8_t > buffer)
	Decode a raw Intel PT trace for a single thread given in buffer and append the decoded instructions and errors in decoded_thread.
llvm::Error	lldb_private::trace_intel_pt::DecodeSystemWideTraceForThread (DecodedThread &decoded_thread, TraceIntelPT &trace_intel_pt, const llvm::DenseMap< lldb::cpu_id_t, llvm::ArrayRef< uint8_t > > &buffers, const std::vector< IntelPTThreadContinousExecution > &executions)
	Decode a raw Intel PT trace for a single thread that was collected in a per cpu core basis.
llvm::Expected< std::vector< PSBBlock > >	lldb_private::trace_intel_pt::SplitTraceIntoPSBBlock (TraceIntelPT &trace_intel_pt, llvm::ArrayRef< uint8_t > buffer, bool expect_tscs)
	Given an intel pt trace, split it in chunks delimited by PSB packets.
llvm::Expected< std::optional< uint64_t > >	lldb_private::trace_intel_pt::FindLowestTSCInTrace (TraceIntelPT &trace_intel_pt, llvm::ArrayRef< uint8_t > buffer)
	Find the lowest TSC in the given trace.
