* [MS] Don't escape MS C++ names with \01Reid Kleckner2018-03-161-13/+13
| | | | | | | 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 Espindola2018-02-231-7/+7
| | | | | | | | | | | | | | | 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

| | | | | | | | This reverts commit r325915. It will take some time to fix the failures on a windows host. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@325929 91177308-0d34-0410-b5e6-96231b3b80d8

* [WinEH] Annotate calls to __RTtypeid with a funclet bundleDavid Majnemer2016-01-261-1/+20
| | | | | | | | | | Clang's CodeGen has several paths which end up invoking or calling a function. The one that we used for calls to __RTtypeid did not appropriately annotate the call with a funclet bundle. This fixes PR26329. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@258877 91177308-0d34-0410-b5e6-96231b3b80d8

* MS ABI: Emit more canonical vbptr stores and loadsReid Kleckner2014-10-221-5/+4
| | | | | | | | This eliminates some i8* GEPs and makes the IR that clang emits a bit more canonical. More work is needed for vftables, but that isn't a clear win so I plan to send it for review. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@220398 91177308-0d34-0410-b5e6-96231b3b80d8
* CodeGen: Cleanup MS ABI RTTI LLVM IRDavid Majnemer2014-07-071-4/+4
| | | | | | | | | | | | | The MS ABI RTTI emission code would choose names for IR types like %"MSRTTITypeDescriptor\02". This name is undesirable because it requires escaping; the underlying reason for this is that the name is unprintable. Fix this by naming it %rtti.TypeDescriptor2. While here, stop trying to do lookups in the LLVM Module's type table. Instead, store the IR types in MicrosoftCXXABI. Lookups by name aren't particularly fast. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@212439 91177308-0d34-0410-b5e6-96231b3b80d8
* MS ABI: Add an additional test for typeidDavid Majnemer2014-06-231-0/+7
| | | | | | | This tests typeid with polymorphic arguments which have an extendable virtual function table. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211505 91177308-0d34-0410-b5e6-96231b3b80d8

* CodeGen: typeid/dynamic_cast tests don't need assertsDavid Majnemer2014-06-201-6/+3
| | | | | | | These tests relied on information that was only available for clang builds that included asserts. Fix these tests to lift that restriction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211408 91177308-0d34-0410-b5e6-96231b3b80d8
* CodeGen: Refactor dynamic_cast and typeidDavid Majnemer2014-06-201-42/+32
| | | | | | | | | | | This refactors the emission of dynamic_cast and typeid expressions so that ABI specific knowledge lives in appropriate places. There are quite a few benefits for having the two implementations share a common core like sharing logic for optimization opportunities. While we are at it, clean up the tests. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211402 91177308-0d34-0410-b5e6-96231b3b80d8
* [MS-ABI] Implement typeidWarren Hunt2014-06-181-0/+58
This patch enables clang to generate calls to __RTtypeid when lowering typeid on win32 targets. Test cases are included. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211223 91177308-0d34-0410-b5e6-96231b3b80d8
