Matthew Simpson 05237a905d Add CalledValuePropagation pass ... This patch adds a new pass for attaching !callees metadata to indirect call sites. The pass propagates values to call sites by performing an IPSCCP-like analysis using the generic sparse propagation solver. For indirect call sites having a small set of possible callees, the attached metadata indicates what those callees are. The metadata can be used to facilitate optimizations like intersecting the function attributes of the possible callees, refining the call graph, performing indirect call promotion, etc. Differential Revision: https://reviews.llvm.org/D37355 llvm-svn: 316576		2017-10-25 13:40:08 +00:00
