* Don't compute a patched/semantic storage class.Rafael Espindola2013-04-031-1/+1
| | | | | | | | | | | 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. llvm-svn: 178663

* Don't eagerly emit a global static merged with a local extern.Rafael Espindola2012-12-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 170827

I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. llvm-svn: 169237

* Support the tls_model attribute (PR9788)Hans Wennborg2012-06-231-4/+14
| | | | | | | | | | | | | | 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. For example, a variable might be declared as: __thread int x __attribute__((tls_model("initial-exec"))); if it will not be used in a shared library that is dlopen'ed. This depends on LLVM r159077. llvm-svn: 159078

* This patch adds a new Clang compiler flag "-gline-tables-only".Alexey Samsonov2012-05-041-10/+20
| | | | | | | | | | | | | | It reduces the amount of emitted debug information: 1) DIEs in .debug_info have types DW_TAG_compile_unit, DW_TAG_subprogram, DW_TAG_inlined_subroutine (for opt builds) and DW_TAG_lexical_block only. 2) .debug_str contains only function names. 3) No debug data for types/namespaces/variables is emitted. 4) The data in .debug_line is enough to produce valid stack traces with function names and line numbers.

* Revert r153723, and its follow-ups r153728 and r153733.Chandler Carruth2012-03-301-96/+55
| | | | | | | | | | | | | | | | 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. llvm-svn: 153768

* When emitting a static local variable in C++, handleJohn McCall2012-03-301-0/+18
| | | | | | | | | | | | | | | 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. llvm-svn: 153723
