Erik Eckstein	d25b1ed834	Optimizer: Replace the MandatoryCombine pass with a Simplification pass, which is implemented in Swift ... The Swift Simplification pass can do more than the old MandatoryCombine pass: simplification of more instruction types and dead code elimination. The result is a better -Onone performance while still keeping debug info consistent. Currently following code patterns are simplified: * `struct` -> `struct_extract` * `enum` -> `unchecked_enum_data` * `partial_apply` -> `apply` * `br` to a 1:1 related block * `cond_br` with a constant condition * `isConcrete` and `is_same_metadata` builtins More simplifications can be added in the future. rdar://96708429 rdar://104562580	2023-02-09 06:50:05 +01:00
Slava Pestov	1e8ce52736	SIL: Strip [serialized] flag from functions even at -Onone ... While the comment is correct to state that this won't enable any new optimizations with -Onone, it does enable IRGen's lazy function emission, which is important for 'reasync' functions, which we don't want to emit at all even at -Onone. This fixes debug stdlib builds with the new reasync versions of the &&, || and ?? operators.	2021-04-08 01:47:27 -04:00

Michael Gottesman	b9046c6d03	[polymorphic-builtin] Rather than asserting in IRGen if we see a builtin that was not specialized, turn the builtin into a trap. ... I forgot about this part of the design when I was working on this. To ensure that the whole design works as expected, I included a small end-to-end test using an experimental design for simd that uses polymorphic builtins that test this functionally. NOTE: The experimental design is only intended to exercise the code functionally. rdar://48248417	2019-09-23 13:51:01 -07:00
