* [MS] Don't escape MS C++ names with \01Reid Kleckner2018-03-161-2/+2
| | | | | | | It is not needed after LLVM r327734. Now it will be easier to copy-paste IR symbol names from Clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@327738 91177308-0d34-0410-b5e6-96231b3b80d8
* Bring r325915 back.Rafael Espindola2018-02-231-1/+1
| | | | | | | | | | | | | | | The tests that failed on a windows host have been fixed. Original message: Start setting dso_local for COFF. With this there are still some GVs where we don't set dso_local because setGVProperties is never called. I intend to fix that in followup commits. This is just the bare minimum to teach shouldAssumeDSOLocal what it should do for COFF. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@325940 91177308-0d34-0410-b5e6-96231b3b80d8

* Make '-disable-llvm-optzns' an alias for '-disable-llvm-passes'.Chandler Carruth2016-12-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Much to my surprise, '-disable-llvm-optzns' which I thought was the magical flag I wanted to get at the raw LLVM IR coming out of Clang deosn't do that. It still runs some passes over the IR. I don't want that, I really want the *raw* IR coming out of Clang and I strongly suspect everyone else using it is in the same camp. There is actually a flag that does what I want that I didn't know about called '-disable-llvm-passes'. I suspect many others don't know about it either. It both does what I want and is much simpler. This removes the confusing version and makes that spelling of the flag an alias for '-disable-llvm-passes'. I've also moved everything in Clang to use the 'passes' spelling as it seems both more accurate (*all* LLVM passes are disabled, not just optimizations) and much easier to remember and spell correctly. This is part of simplifying how Clang drives LLVM to make it cleaner to wire up to the new pass manager.

* CodeGen: Start using inrange annotations on vtable getelementptr.Peter Collingbourne2016-12-131-7/+7
| | | | | | | | | | | | This annotation allows the optimizer to split vtable groups, as permitted by a change to the Itanium ABI [1] that prevents compilers from adjusting virtual table pointers between virtual tables.

* CodeGen: New vtable group representation: struct of vtable arrays.Peter Collingbourne2016-12-131-19/+19
| | | | | | | | | In a future change, this representation will allow us to use the new inrange annotation on getelementptr to allow the optimizer to split vtable groups.

* CodeGen: Use 32-bit gep offsets to address vtable address points.Peter Collingbourne2016-03-141-7/+7
| | | | | | | | | | | | | | | | | The relative vtable ABI will use a struct rather than an array as the type of a vtable. LLVM only allows 32-bit integers as struct indices, so we need to use 32-bit integers to get addresses of address points. In order to keep the code simple, we might as well do that unconditionally. It's probably a reasonable implementation limit to support no more than 2 billion virtual functions per class. This change causes quite a bit of churn in the test suite, so I'm making it separately.

* Assume loads fix #2Piotr Padlewski2015-08-271-5/+128
| | | | | | | | | | | | | There was linker problem, and it turns out that it is not always safe to refer to vtable. If the vtable is used, then we can refer to it without any problem, but because we don't know when it will be used or not, we can only check if vtable is external or it is safe to to emit it speculativly (when class it doesn't have any inline virtual functions). It should be fixed in the future. http://reviews.llvm.org/D12385 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@246214 91177308-0d34-0410-b5e6-96231b3b80d8
