[PATCH] D153771: [BOLT][Instrumentation] Fix hash table memory corruption and append-pid option

[Denis Revunov via Phabricator via llvm-commits]

treapster added a comment.

Turns out, the [unknown] entries in profile are because addresses in indirect call descriptions are not relocated, which makes them meaningless in PIE because of ASLR. When the test is compiled with no-pie, indirect calls are recorded accurately. So, we should either compute base address and add it to stored entries, or produce dynamic relocations.
