2012-04-15PR12226: don't generate wrong code if a braced string literal is used toRichard Smith
initialize an array of unsigned char. Outside C++11 mode, this bug was benign, and just resulted in us emitting a constant which was double the required length, padded with 0s. In C++11, it resulted in us generating an array whose first element was something like i8 ptrtoint ([n x i8]* @str to i8). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154756 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-06Use atexit when __cxa_atexit isn't available instead of adding aJohn McCall
global destructor entry. For some reason this isn't enabled for apple-kexts; it'd be good to have documentation for that. Based on a patch by Nakamura Takumi! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154191 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-30Make sure we unique static-local decls across multiple emissions ofJohn McCall
the function body, but do so in a way that doesn't make any assumptions about the static local actually having a proper, unique mangling, since apparently we don't do that correctly at all. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153776 91177308-0d34-0410-b5e6-96231b3b80d8
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
2012-03-30Do the static-locals thing properly in the face of unions andJohn McCall
other things which might mess with the variable's type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153733 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

2011-03-22Fix a test case and teach ClearLinkageCache() to clear the linkage ofJohn McCall
a function template decl's pattern, which was suddenly exposed by my last patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128073 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-08Implement ARM static local initialization guards, which are more compact thanJohn McCall
Itanium guards and use a slightly different compiled-in API. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113330 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-04Correctly align large arrays in x86-64. This fixes PR5599.Rafael Espindola
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105500 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-25If a function definition has any sort of weak linkage, its static localJohn McCall
variables should have that linkage. Otherwise, its static local variables should have internal linkage. To avoid computing this excessively, set a function's linkage before we emit code for it. Previously we were assigning weak linkage to the static variables of static inline functions in C++, with predictably terrible results. This fixes that and also gives better linkage than 'weak' when merging is required. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104581 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-05For thread-safe static initialization of local statics withDouglas Gregor
destructors, place the __cxa_atexit call after the __cxa_guard_release call, mimicking GCC/LLVM-GCC behavior. Noticed while debugging something related. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103088 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-03Just bail out immediately when emitting an unreachable function-local staticJohn McCall
variable. Surprisingly, this does seem to be the right way to solve this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102961 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-15Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar
- This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91446 91177308-0d34-0410-b5e6-96231b3b80d8
