* [MS] Don't escape MS C++ names with \01Reid Kleckner2018-03-161-5/+5
| | | | | | | It is not needed after LLVM r327734. Now it will be easier to copy-paste IR symbol names from Clang. llvm-svn: 327738
* Bring r325915 back.Rafael Espindola2018-02-231-2/+2
| | | | | | | | | | | | | | | 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

* [MS ABI] Add /include directives for dynamic TLSDavid Majnemer2016-09-121-0/+5
| | | | | | | | | MSVC emits /include directives in the .drective section for the __dyn_tls_init function (decorated as ___dyn_tls_init@12 for 32-bit). This fixes PR30347. llvm-svn: 281189

* MS ABI: Implement thread_local for global variablesDavid Majnemer2014-10-051-0/+28
Summary: This add support for the C++11 feature, thread_local global variables. The ABI Clang implements is an improvement of the MSVC ABI. Sadly, further improvements could be made but not without sacrificing ABI compatibility. The feature is implemented as follows: - All thread_local initialization routines are pointed to from the .CRT$XDU section. - All non-weak thread_local variables have their initialization routines call from a single function instead of getting their own .CRT$XDU section entry. This is done to open up optimization opportunities to the compiler. - All weak thread_local variables have their own .CRT$XDU section entry. This entry is in a COMDAT with the global variable it is initializing; this ensures that we will initialize the global exactly once. - Destructors are registered in the initialization function using __tlregdtor.
