Add serialization support for function metadata attachments (added in r235783). The syntax is: define @foo() !attach !0 { Metadata attachments are only allowed on functions with bodies. Since they come before the `{`, they're not really part of the body; since they require a body, they're not really part of the header. In `LLParser` I gave them a separate function called from `ParseDefine()`, `ParseOptionalFunctionMetadata()`. In bitcode, I'm using the same `METADATA_ATTACHMENT` record used by instructions. Instruction metadata attachments are included in a special "attachment" block at the end of a `Function`. The attachment records are laid out like this: InstID (KindID MetadataID)+ Note that these records always have an odd number of fields. The new code takes advantage of this to recognize function attachments (which don't need an instruction ID): (KindID MetadataID)+ This means we can use the same attachment block already used for instructions. This is part of PR23340. llvm-svn: 235785 |
