| | | | | | | | | | | | | | | | Also create isValidElementType for ArrayType, PointerType, StructType and VectorType. Make LLParser use them. This closes up some holes like an assertion failure on: %x = type {label} but largely doesn't change any semantics. The only thing we accept now which we didn't before is vectors of opaque type such as "<4 x opaque>". The opaque can be resolved to an int or float when linking. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73016 91177308-0d34-0410-b5e6-96231b3b80d8

For now, the AsmParser, BitcodeReader, and IRBuilder all preserve backwards compatability, and the Core LLVM APIs preserve backwards compatibility for IR producers.

* Fix a bug in our autoupgrade support: in an argument list to a functionChris Lattner2009-03-251-4/+8
| | | | | | | | | | | | | | call, we should treat "i64 zext" as the start of a constant expr, but "i64 0 zext" as an argument with an obsolete attribute on it (this form is already tested by test/Assembler/2007-07-30-AutoUpgradeZextSext.ll). Make the autoupgrade logic more discerning to avoid treating "i64 zext" as an old-style attribute, causing us to reject a valid constant expr. This fixes PR3876. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67682 91177308-0d34-0410-b5e6-96231b3b80d8

* Introduce new linkage types linkonce_odr, weak_odr, common_odrDuncan Sands2009-03-073-24/+48
| | | | | | | | | | | | | | | | | | | | | | 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
