Detailed Description

Canonicalizer for mangled names.

This class allows specifying a list of "equivalent" manglings. For example, you can specify that Ss is equivalent to NSt3__112basic_stringIcNS_11char_traitsIcEENS_9allocatorIcEEEE and then manglings that refer to libstdc++'s 'std::string' will be considered equivalent to manglings that are the same except that they refer to libc++'s 'std::string'.

This can be used when data (eg, profiling data) is available for a version of a program built in a different configuration, with correspondingly different manglings.

◆ EquivalenceError

enum class llvm::ItaniumManglingCanonicalizer::EquivalenceError

strong

Enumerator
Success
ManglingAlreadyUsed	Both the equivalent manglings have already been used as components of some other mangling we've looked at. It's too late to add this equivalence.
InvalidFirstMangling	The first equivalent mangling is invalid.
InvalidSecondMangling	The second equivalent mangling is invalid.

◆ FragmentKind

enum class llvm::ItaniumManglingCanonicalizer::FragmentKind

strong

Enumerator
Name	The mangling fragment is a <name> (or a predefined <substitution>).
Type	The mangling fragment is a <type>.
Encoding	The mangling fragment is an <encoding>.
