* [IR] Disallow llvm.global_ctors and llvm.global_dtors of the 2-field form in ↵Fangrui Song2019-05-151-5/+5
| | | | | | | | | | | | | | | | | | | | textual format The 3-field form was introduced by D3499 in 2014 and the legacy 2-field form was planned to be removed in LLVM 4.0 For the textual format, this patch migrates the existing 2-field form to use the 3-field form and deletes the compatibility code. test/Verifier/global-ctors-2.ll checks we have a friendly error message. For bitcode, lib/IR/AutoUpgrade UpgradeGlobalVariables will upgrade the 2-field form (add i8* null as the third field).

* Invariant start/end intrinsics overloaded for address spaceAnna Thomas2016-07-221-5/+5
| | | | | | | | | | | | | | | | | | | | | | Summary: The llvm.invariant.start and llvm.invariant.end intrinsics currently support specifying invariant memory objects only in the default address space. With this change, these intrinsics are overloaded for any adddress space for memory objects and we can use these llvm invariant intrinsics in non-default address spaces. Example: llvm.invariant.start.p1i8(i64 4, i8 addrspace(1)* %ptr) This overloaded intrinsic is needed for representing final or invariant memory in managed languages.

* Add support for invariant.start inside the static constructor evaluator. This isNick Lewycky2012-02-171-0/+34
useful to represent a variable that is const in the source but can't be constant in the IR because of a non-trivial constructor. If globalopt evaluates the constructor, and there was an invariant.start with no matching invariant.end possible, it will mark the global constant afterwards. llvm-svn: 150794
