Support token type in struct for landingpad
Hi David,
Sorry to bother you, but I would like to get some suggestions on your recent work of token type.
I’m currently working on changing gc.statepoint to return a token type instead of a i32 type. The reason is that with the current implementation, gc.statepoint could potentially be fed into PHI nodes, and break RewriteStatepointsForGC pass later. Using token type would help us to avoid
