Gor Nishanov 5eb585836a [coroutines] Add codegen for await and yield expressions ... Details: Emit suspend expression which roughly looks like: auto && x = CommonExpr(); if (!x.await_ready()) { llvm_coro_save(); x.await_suspend(...); (*) llvm_coro_suspend(); (**) } x.await_resume(); where the result of the entire expression is the result of x.await_resume() (*) If x.await_suspend return type is bool, it allows to veto a suspend: if (x.await_suspend(...)) llvm_coro_suspend(); (**) llvm_coro_suspend() encodes three possible continuations as a switch instruction: %where-to = call i8 @llvm.coro.suspend(...) switch i8 %where-to, label %coro.ret [ ; jump to epilogue to suspend i8 0, label %yield.ready ; go here when resumed i8 1, label %yield.cleanup ; go here when destroyed ] llvm-svn: 298784		2017-03-26 02:18:05 +00:00
