2017-10-27[LLVM-C] Publicly expose getters of MetadataType, TokenTypewhitequark
Patch by Robert Widmann. Expose getters for MetadataType and TokenType publicly in the C API. Discovered a need for these while trying to wrap the intrinsics API.

2017-04-17Introducing LLVMMetadataRefAmaury Sechet
Summary: This seems like an uncontroversial first step toward providing access to the metadata hierarchy that now exists in LLVM. This should allow for good debug info support from C. Future plans are to deprecate API that take mixed bags of values and metadata (mainly the LLVMMDNode family of functions) and migrate the rest toward the use of LLVMMetadataRef. Once this is in place, mapping of DIBuilder will be able to start.

2015-12-12[IR] Reformulate LLVM's EH funclet IRDavid Majnemer
While we have successfully implemented a funclet-oriented EH scheme on top of LLVM IR, our scheme has some notable deficiencies: - catchendpad and cleanupendpad are necessary in the current design but they are difficult to explain to others, even to seasoned LLVM experts. - catchendpad and cleanupendpad are optimization barriers. They cannot be split and force all potentially throwing call-sites to be invokes. This has a noticable effect on the quality of our code generation. - catchpad, while similar in some aspects to invoke, is fairly awkward. It is unsplittable, starts a funclet, and has control flow to other funclets. - The nesting relationship between funclets is currently a property of control flow edges. Because of this, we are forced to carefully analyze the flow graph to see if there might potentially exist illegal nesting among funclets. While we have logic to clone funclets when they are illegally nested, it would be nicer if we had a representation which forbade them upfront. Let's clean this up a bit by doing the following: - Instead, make catchpad more like cleanuppad and landingpad: no control flow, just a bunch of simple operands; catchpad would be splittable. - Introduce catchswitch, a control flow instruction designed to model the constraints of funclet oriented EH. - Make funclet scoping explicit by having funclet instructions consume the token produced by the funclet which contains them. - Remove catchendpad and cleanupendpad. Their presence can be inferred implicitly using coloring information. N.B. The state numbering code for the CLR has been updated but the veracity of it's output cannot be spoken for. An expert should take a look to make sure the results are reasonable.

2015-11-11[IR] Add support for empty tokensDavid Majnemer
When working with tokens, it is often the case that one has instructions which consume a token and produce a new token. Currently, we have no mechanism to represent an initial token state. Instead, we can create a notional "empty token" by inventing a new constant which captures the semantics we would like. This new constant is called ConstantTokenNone and is written textually as "token none".

2015-09-03[WinEH] Add cleanupendpad instructionJoseph Tremoulet
Summary: Add a `cleanupendpad` instruction, used to mark exceptional exits out of cleanups (for languages/targets that can abort a cleanup with another exception). The `cleanupendpad` instruction is similar to the `catchendpad` instruction in that it is an EH pad which is the target of unwind edges in the handler and which itself has an unwind edge to the next EH action. The `cleanupendpad` instruction, similar to `cleanupret` has a `cleanuppad` argument indicating which cleanup it exits. The unwind successors of a `cleanuppad`'s `cleanupendpad`s must agree with each other and with its `cleanupret`s. Update WinEHPrepare (and docs/tests) to accomodate `cleanupendpad`.

2015-08-14[IR] Add token typesDavid Majnemer
This introduces the basic functionality to support "token types". The motivation stems from the need to perform operations on a Value whose provenance cannot be obscured. There are several applications for such a type but my immediate motivation stems from WinEH. Our personality routine enforces a single-entry - single-exit regime for cleanups. After several rounds of optimizations, we may be left with a terminator whose "cleanup-entry block" is not entirely clear because control flow has merged two cleanups together. We have experimented with using labels as operands inside of instructions which are not terminators to indicate where we came from but found that LLVM does not expect such exotic uses of BasicBlocks. Instead, we can use this new type to clearly associate the "entry point" and "exit point" of our cleanup. This is done by having the cleanuppad yield a Token and consuming it at the cleanupret. The token type makes it impossible to obscure or otherwise hide the Value, making it trivial to track the relationship between the two points. What is the burden to the optimizer? Well, it turns out we have already paid down this cost by accepting that there are certain calls that we are not permitted to duplicate, optimizations have to watch out for such instructions anyway. There are additional places in the optimizer that we will probably have to update but early examination has given me the impression that this will not be heroic.

Revert the changes to the C API LLVMBuildLandingPad that were part of the personality function move. We now set the personality on the parent function when the C API attempts to construct a landingpad with a personality.
