[ThinLTO] Parse module summary index from assembly Summary: Adds assembly parsing support for the module summary index (follow on to r333335 which added the assembly writing support). I added support to llvm-as to invoke the index parsing, so that it can create either a bitcode file with a Module and a per-module index, or a combined index without a Module. I will send follow on patches soon to do the following: - add support to tools such as llvm-lto2 to parse the per-module indexes from assembly instead of bitcode when testing the thin link. - verification support. Depends on D47844 and D47842. Reviewers: pcc, dexonsmith, mehdi_amini Subscribers: inglorion, eraman, steven_wu, llvm-commits Differential Revision: https://reviews.llvm.org/D47905 llvm-svn: 335602

; Test TypeId summaries:
[ThinLTO] Efficiency fix for writing type id records in per-module indexes Summary: In D49565/r337503, the type id record writing was fixed so that only referenced type ids were emitted into each per-module index for ThinLTO distributed builds. However, this still left an efficiency issue: each per-module index checked all type ids for membership in the referenced set, yielding O(M*N) performance (M indexes and N type ids). Change the TypeIdMap in the summary to be indexed by GUID, to facilitate correlating with type identifier GUIDs referenced in the function summary TypeIdInfo structures. This allowed simplifying other places where a map from type id GUID to type id map entry was previously being used to aid this correlation. Also fix AsmWriter code to handle the rare case of type id GUID collision. For a large internal application, this reduced the thin link time by almost 15%.

[ThinLTO] Split NotEligibleToImport into legality and inlinability flags Summary: The NotEligibleToImport flag on the GlobalValueSummary was set if it isn't legal to import (e.g. because it references unpromotable locals) and when it can't be inlined (in which case importing is pointless). I split out the inlinable piece into a separate flag on the FunctionSummary (doesn't make sense for aliases or global variables), because in the future we may want to import for reasons other than inlining.

I added support to llvm-as to invoke the index parsing, so that it can create either a bitcode file with a Module and a per-module index, or a combined index without a Module. I will send follow on patches soon to do the following: - add support to tools such as llvm-lto2 to parse the per-module indexes from assembly instead of bitcode when testing the thin link. - verification support.

[ThinLTO] Handle optional args in assembly format for ConstVCalls Summary: The AsmWriter was only writing the Args for a ConstVCall if it was non-empty, however, the LLParser was always expecting it. To aid in making it optional, surround the ConstVCall VFuncId and Args in parentheses when writing, then make the Args optional when reading.

[ThinLTO] Efficiency fix for writing type id records in per-module indexes Summary: In D49565/r337503, the type id record writing was fixed so that only referenced type ids were emitted into each per-module index for ThinLTO distributed builds. However, this still left an efficiency issue: each per-module index checked all type ids for membership in the referenced set, yielding O(M*N) performance (M indexes and N type ids). Change the TypeIdMap in the summary to be indexed by GUID, to facilitate correlating with type identifier GUIDs referenced in the function summary TypeIdInfo structures. This allowed simplifying other places where a map from type id GUID to type id map entry was previously being used to aid this correlation. Also fix AsmWriter code to handle the rare case of type id GUID collision. For a large internal application, this reduced the thin link time by almost 15%.
