* [MS] Don't escape MS C++ names with \01Reid Kleckner2018-03-161-14/+14
| | | | | | | It is not needed after LLVM r327734. Now it will be easier to copy-paste IR symbol names from Clang. llvm-svn: 327738
* [MS] Always use base dtors in place of complete/vbase dtors when possibleReid Kleckner2018-03-161-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Previously we tried too hard to uphold the fiction that destructor variants work like they do on Itanium throughout the ABI-neutral parts of clang. This lead to MS C++ ABI incompatiblities and other bugs. Now, -mconstructor-aliases will no longer control this ABI detail, and clang -cc1's LLVM IR output will be this much closer to the clang driver's. Based on a patch by Zahira Ammarguellat: https://reviews.llvm.org/D39063 I've tried to move the logic that Zahira added into MicrosoftCXXABI.cpp. There is only one ABI-specific detail sticking out, and that is in CodeGenModule::getAddrOfCXXStructor, where we collapse complete dtors to base dtors in the MS ABI. This fixes PR32990. Reviewers: erichkeane, zahiraam, majnemer, rjmccall Subscribers: cfe-commits Differential Revision: https://reviews.llvm.org/D44505 llvm-svn: 327732
* Bring r325915 back.Rafael Espindola2018-02-231-8/+8
| | | | | | | | | | | | | | | 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. llvm-svn: 325940
* Revert "Start setting dso_local for COFF."Rafael Espindola2018-02-231-8/+8
| | | | | | | | This reverts commit r325915. It will take some time to fix the failures on a windows host. llvm-svn: 325929

* Emit DeferredDeclsToEmit in a DFS order.Rafael Espindola2015-01-221-3/+3
| | | | | | | | | | | | | | Currently we emit DeferredDeclsToEmit in reverse order. This patch changes that. The advantages of the change are that * The output order is a bit closer to the source order. The change to test/CodeGenCXX/pod-member-memcpys.cpp is a good example. * If we decide to deffer more, it will not cause as large changes in the estcases as it would without this patch. llvm-svn: 226751
* Remove the -cxx-abi command-line flag.Hans Wennborg2014-01-141-1/+1
| | | | | | | | | | | | | | | This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples, Itanium otherwise. It's no longer possible to do weird combinations. To be able to run a test with a specific ABI without constraining it to a specific triple, new substitutions are added to lit: %itanium_abi_triple and %ms_abi_triple can be used to get the current target triple adjusted to the desired ABI. For example, if the test suite is running with the i686-pc-win32 target, %itanium_abi_triple will expand to i686-pc-mingw32.
