class SampleContextTrimmer

Declaration

class SampleContextTrimmer { /* full declaration omitted */ };

Description

SampleContextTrimmer impelements helper functions to trim, merge cold context profiles. It also supports context profile canonicalization to make sure ProfileMap's key is consistent with FunctionSample's name/context.
