Member Enumeration Documentation

◆ ChecksumKind

enum llvm::DIFile::ChecksumKind

Which algorithm (e.g.

MD5) a checksum was generated with.

The encoding is explicit because it is used directly in Bitcode. The value 0 is reserved to indicate the absence of a checksum in Bitcode.

Enumerator
CSK_MD5
CSK_SHA1
CSK_SHA256
