Additional Inherited Members
Static Public Member Functions inherited from llvm::sampleprof::SampleProfileWriter
static ErrorOr< std::unique_ptr< SampleProfileWriter > > create (StringRef Filename, SampleProfileFormat Format)
Profile writer factory.
static ErrorOr< std::unique_ptr< SampleProfileWriter > > create (std::unique_ptr< raw_ostream > &OS, SampleProfileFormat Format)
Create a new stream writer based on the value of Format.
Protected Attributes inherited from llvm::sampleprof::SampleProfileWriter
size_t LineCount
For writeWithSizeLimit in text mode, each newline takes 1 additional byte on Windows when actually written to the file, but not written to a memory buffer.
std::unique_ptr< raw_ostream > OutputStream
Output stream where to emit the profile to.
std::unique_ptr< ProfileSummary > Summary
Profile summary.
SampleProfileFormat Format = SPF_None
Profile format.

◆ writeSample()

Write samples to a text file.

Note: it may be tempting to implement this in terms of FunctionSamples::print(). Please don't. The dump functionality is intended for debugging and has no specified form.

The format used here is more structured and deliberate because it needs to be parsed by the SampleProfileReaderText class.

Implements llvm::sampleprof::SampleProfileWriter.
