Oli Scherer	3127a9c60f	Prepare mir::Constant for ty::Const only supporting valtrees	2021-03-12 12:43:54 +00:00
kadmin	217ff6b7ea	Switch to changing cp_non_overlap in tform ... It was suggested to lower this in MIR instead of ssa, so do that instead.	2021-03-09 16:54:14 +00:00
Oli Scherer	9a2362e5a9	Shrink the size of Rvalue by 16 bytes	2021-03-05 09:33:01 +00:00
Tomasz Miąsko	686237c49a	Lower discriminant_value intrinsic ... This allows const propagation to evaluate comparisons involving field-less enums using derived implementations of `PartialEq` (after inlining `eq`).	2020-12-11 03:25:40 +01:00
Tomasz Miąsko	2b7ffecee0	Don't special case constant operands when lowering intrinsics	2020-11-16 00:00:00 +00:00
Tomasz Miąsko	6903273339	Lower intrinsics calls: forget, size_of, unreachable, wrapping_* ... This allows constant propagation to evaluate `size_of` and `wrapping_*`, and unreachable propagation to propagate a call to `unreachable`. The lowering is performed as a MIR optimization, rather than during MIR building to preserve the special status of intrinsics with respect to unsafety checks and promotion.	2020-11-14 00:00:00 +00:00
