This patch adds support for optional memory profile information to be included with and indexed profile. The indexed profile header adds a new field which points to the offset of the memory profile section (if present) in the indexed profile. For users who do not utilize this feature the only overhead is a 64-bit offset in the header. The memory profile section contains (1) profile metadata describing the information recorded for each entry (2) an on-disk hashtable containing the profile records indexed via llvm::md5(function_name). We chose to introduce a separate hash table instead of the existing one since the indexing for the instrumented fdo hash table is based on a CFG hash which itself is perturbed by memprof instrumentation. This commit also includes the changes reviewed separately in D120093. Differential Revision: https://reviews.llvm.org/D120103 |
