Erik Eckstein	cc92319c3d	Optimizer: support partial_apply of thunks in the copy_block simplification. ... If the block is passed to another function - either as closure argument or as closure capture - it's "converted" to a swift closure with the help of a thunk. The thunk just calls the block. If this is done with a non-escaping partial_apply, the block does not escape. rdar://149095630	2025-05-06 17:57:37 +02:00

Erik Eckstein	d8fddc9dcc	Optimizer: remove redundant copy_block instructions ... Removes a `copy_block` if its only uses, beside ownership instructions, are callees of function calls ``` %2 = copy_block %0 %3 = begin_borrow [lexical] %2 %4 = apply %3() : $@convention(block) @noescape () -> () end_borrow %3 destroy_value %2 ``` -> ``` %4 = apply %0() : $@convention(block) @noescape () -> () ``` rdar://118521396	2025-04-16 14:33:26 +02:00
