static

Create a remapper from the given Buffer.

Create a sample profile remapper from the given input, to remap the function names in the given profile data.

The remapper will be used for profile read in by Reader.

Parameters

B	The memory buffer to create the reader from (assumes ownership).
C	The LLVM context to use to emit diagnostics.
Reader	The profile reader the remapper is going to be applied to.

Returns

an error code indicating the status of the created reader.

static

Create a remapper from the given remapping file.

Create a sample profile remapper from the given input, to remap the function names in the given profile data.
