// This is a utility class for instrumentation passes (like AddressSanitizer
|
|
// or ThreadSanitizer) to avoid instrumenting some functions or global
|
|
// variables based on a user-supplied blacklist.
|
|
//
|
|
// The blacklist disables instrumentation of various functions and global
|
|
// variables. Each line contains a prefix, followed by a wild card expression.
|
|
// Empty lines and lines starting with "#" are ignored.
|

// # Blacklisted items:
|
|
// fun:*_ZN4base6subtle*
|
|
// global:*global_with_bad_access_or_initialization*
|
|
// global-init:*global_with_initialization_issues*
|

// global-init-type:*Namespace::ClassName*

// Note that the wild card is in fact an llvm::Regex, but * is automatically
|
|
// replaced with .*
|
|
// This is similar to the "ignore" feature of ThreadSanitizer.
