* Introduce new linkage types linkonce_odr, weak_odr, common_odrDuncan Sands2009-03-071-3/+5
| | | | | | | | | | | | | | | | | | | | | | and extern_weak_odr. These are the same as the non-odr versions, except that they indicate that the global will only be overridden by an *equivalent* global. In C, a function with weak linkage can be overridden by a function which behaves completely differently. This means that IP passes have to skip weak functions, since any deductions made from the function definition might be wrong, since the definition could be replaced by something completely different at link time. This is not allowed in C++, thanks to the ODR (One-Definition-Rule): if a function is replaced by another at link-time, then the new function must be the same as the original function. If a language knows that a function or other global can only be overridden by an equivalent global, it can give it the weak_odr linkage type, and the optimizers will understand that it is alright to make deductions based on the function body. The code generators on the other hand map weak and weak_odr linkage to the same thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66339 91177308-0d34-0410-b5e6-96231b3b80d8
* Treat [1 x i8] zeroinitializer as a C string, placing such stuff intoasl2009-01-271-2/+1
| | | | | | | | | | | | mergeable string section. I don't see any bad impact of such decision (rather then placing it into mergeable const section, as it was before), but at least Darwin linker won't complain anymore. The problem in LLVM is that we don't have special type for string constants (like gcc does). Even more, we have two separate types: ConstatArray for non-null strings and ConstantAggregateZero for null stuff.... It's a bit weird :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63142 91177308-0d34-0410-b5e6-96231b3b80d8
