2013-04-03Don't compute a patched/semantic storage class.Rafael Espindola
For variables and functions clang used to store two storage classes. The one "as written" in the code and a patched one, which, for example, propagates static to the following decls. This apparently is from the days clang lacked linkage computation. It is now redundant and this patch removes it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178663 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-21Don't eagerly emit a global static merged with a local extern.Rafael Espindola
When we are visiting the extern declaration of 'i' in static int i = 99; int foo() { extern int i; return i; } We should not try to handle it as if it was an function static. That is, we must consider the written storage class. Fixing this then exposes that the assert in EmitGlobalVarDeclLValue and the if leading to its call are not completely accurate. They were passing before because the second decl was marked as having external storage. I changed them to check the linkage, which I find easier to understand. Last but not least, there is something strange going on with cuda and opencl. My guess is that the linkage computation for these languages needs to be audited, but I didn't want to change that in this patch so I just updated the storage classes to keep the current behavior. Thanks to Reed Kotler for reporting this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170827 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-23Support the tls_model attribute (PR9788)Hans Wennborg
This adds support for the tls_model attribute. This allows the user to choose a TLS model that is better than what LLVM would select by default.

2012-03-30Revert r153723, and its follow-ups r153728 and r153733.Chandler Carruth
These patches cause us to miscompile and/or reject code with static function-local variables in an extern-C context. Previously, we were papering over this as long as the variables are within the same translation unit, and had not seen any failures in the wild. We still need a proper fix, which involves mangling static locals inside of an extern-C block (as GCC already does), but this patch causes pretty widespread regressions. Firefox, and many other applications no longer build. Lots of test cases have been posted to the list in response to this commit, so there should be no problem reproducing the issues. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153768 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-30When emitting a static local variable in C++, handleJohn McCall
the case that the variable already exists. Partly this is just protection against people making crazy declarations with custom asm labels or extern "C" names that intentionally collide with the manglings of such variables, but the main reason is that we can actually emit a static local variable twice with the requirement that it match up. There may be other cases with (e.g.) the various nested functions, but the main exemplar is with constructor variants, where we can be forced into double-emitting the function body under certain circumstances like (currently) the presence of virtual bases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153723 91177308-0d34-0410-b5e6-96231b3b80d8
