* [ASTImporter] Added Import functions for transition to new API.Balazs Keri2018-11-271-32/+73
| | | | | | | | | | | | | | | | | | | | | | | Summary: These Import_New functions should be used in the ASTImporter, and the old Import functions should not be used. Later the Import_New should be renamed to Import again and the old Import functions must be removed. But this can happen only after LLDB was updated to use the new Import interface. This commit is only about introducing the new Import_New functions. These are not implemented now, only calling the old Import ones.

* [clang][Parse] Diagnose useless null statements / empty init-statementsRoman Lebedev2018-11-203-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: clang has `-Wextra-semi` (D43162), which is not dictated by the currently selected standard. While that is great, there is at least one more source of need-less semis - 'null statements'. Sometimes, they are needed: ``` for(int x = 0; continueToDoWork(x); x++) ; // Ugly code, but the semi is needed here. ``` But sometimes they are just there for no reason: ``` switch(X) { case 0: return -2345; case 5: return 0; default: return 42; }; // <- oops ;;;;;;;;;;; <- OOOOPS, still not diagnosed. Clearly this is junk. ``` Additionally: ``` if(; // <- empty init-statement true) ; switch (; // empty init-statement x) { ... } for (; // <- empty init-statement int y : S()) ; } As usual, things may or may not go sideways in the presence of macros. While evaluating this diag on my codebase of interest, it was unsurprisingly discovered that Google Test macros are *very* prone to this. And it seems many issues are deep within the GTest itself, not in the snippets passed from the codebase that uses GTest. So after some thought, i decided not do issue a diagnostic if the semi is within *any* macro, be it either from the normal header, or system header.

* [codeview] Expose -gcodeview-ghash for global type hashingReid Kleckner2018-11-162-0/+9
| | | | | | | | | | | | | | | | | | | | | Summary: Experience has shown that the functionality is useful. It makes linking optimized clang with debug info for me a lot faster, 20s to 13s. The type merging phase of PDB writing goes from 10s to 3s. This removes the LLVM cl::opt and replaces it with a metadata flag. After this change, users can do the following to use ghash: - add -gcodeview-ghash to compiler flags - replace /DEBUG with /DEBUG:GHASH in linker flags Reviewers: zturner, hans, thakis, takuto.ikuta Subscribers: aprantl, hiraditya, JDevlieghere, llvm-commits Differential Revision: https://reviews.llvm.org/D54370 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@347072 91177308-0d34-0410-b5e6-96231b3b80d8
