From bb9eb198298099742c823dce11c5edacc9c48d4e Mon Sep 17 00:00:00 2001 From: Petr Hosek Date: Fri, 15 Jan 2021 01:14:37 -0800 Subject: Support for instrumenting only selected files or functions This change implements support for applying profile instrumentation only to selected files or functions. The implementation uses the sanitizer special case list format to select which files and functions to instrument, and relies on the new noprofile IR attribute to exclude functions from instrumentation.
