Hi everyone, It'd be useful for our purposes if we could attach metadata to named structs. In particular, in Rust we're looking to use this information to communicate information about our discriminated unions to the garbage collector. (We could, and are at the moment, using the metadata argument to the gcroot intrinsic, but this seems to inhibit optimizations and adds a fair amount

...I didn't hook Hotpatch up to anything yet, and I don't expect to get to it anytime soon; that's why I'm giving it to them for now.

Hi, I'm interested in adding support for void values (i.e. unit types) to LLVM. Currently, "void" is only allowed as the return value of a function, and numerous assertions are in place to check this. This document [1] that Google pulled up seems to suggest that this idea was planned: > Finally, one annoying, but trivial, nuance of the LLVM type-system is > the

Hi everyone, It looks to me like we're out of bits for function attributes. I need another one, unfortunately... Is there any objection to moving to 64 bits? I can write the patch. Thanks, Patrick
