2009-04-21don't bother emitting a zero byte memset at all. We used to get themChris Lattner
in cases like this: typedef struct { short instance; char name[0]; } ATTR_LIST_ENTRY2; void test() { ATTR_LIST_ENTRY2 X = (ATTR_LIST_ENTRY2) { .instance = 7, }; } While it is safe to emit them, it is pretty silly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69687 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-21Explictly track tentative definitions within Sema, then hand thoseDouglas Gregor
tentative definitions off to the ASTConsumer at the end of the translation unit. Eliminate CodeGen's internal tracking of tentative definitions, and instead hook into ASTConsumer::CompleteTentativeDefinition. Also, tweak the definition-deferal logic for C++, where there are no tentative definitions. Fixes <rdar://problem/6808352>, and will make it much easier for precompiled headers to cope with tentative definitions in the future. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69681 91177308-0d34-0410-b5e6-96231b3b80d8
