The indexed profile header adds a newfield which points to the offset of the memory profile section (ifpresent) in the indexed profile. For users who do not utilize thisfeature the only overhead is a 64-bit offset in the header.The memory profile section contains (1) profile metadata describing theinformation recorded for each entry (2) an on-disk hashtable containingthe profile records indexed via llvm::md5(function_name). We chose tointroduce a separate hash table instead of the existing one since theindexing for the instrumented fdo hash table is based on a CFG hashwhich itself is perturbed by memprof instrumentation.This commit also includes the changes reviewed separately in D120093.Differential Revision: https://reviews.llvm.org/D120103 List of files: /llvm-project-15.0.7/llvm/test/tools/llvm-profdata/Inputs/basic.profraw Fri, 18 Feb 2022 00:01:31 +0000 Snehasish Kumar <snehasishk@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/tools/llvm-profdata/Inputs/basic.profraw#807ba7aa Reland "[memprof] Extend the index prof format to include memory profiles."This reverts commit 85355a560a33897453df2ef959e255ee725eebce.This patch adds support for optional memory profile information to beincluded with and indexed profile.
