Member Function Documentation

Decode()

Expected< DecodedThreadSP > ThreadDecoder::Decode

(

)

Decode the thread and store the result internally, to avoid recomputations.

Returns

A DecodedThread instance.

Definition at line 38 of file ThreadDecoder.cpp.

DoDecode()

llvm::Expected< DecodedThreadSP > ThreadDecoder::DoDecode ( )

private

Definition at line 49 of file ThreadDecoder.cpp.

FindLowestTSC()

Expected< Optional< uint64_t > > ThreadDecoder::FindLowestTSC

(

)

Returns

The lowest TSC value in this trace if available, llvm::None if the trace is empty or the trace contains no timing information, or an llvm::Error if it was not possible to set up the decoder.

Definition at line 23 of file ThreadDecoder.cpp.
