As a result, we're turning it on to get the compile time benefits. `ConstProp` doesn't currently intern the memory used by its `Machine` so we can't yet propagate allocations which is why `ConstProp::should_const_prop()` checks if the value being propagated is a scalar or not. 2019-10-21T03:49:42+00:00 Wesley Wiser wwiser@gmail.com 2019-10-17T10:46:51+00:00 urn:sha1:2ec73395b985a028062cc40faed6ace50be0c67d The `ConstProp` can cause many locals to be initialized to a constant value and then never read from. `ConstProp` can also evaluate ZSTs into constant values. Previously, many of these would be removed by other parts of the MIR optimization pipeline. However, evaluating ZSTs (especially `()`) into constant values defeated those parts of the optimizer and so in a2e3ed5c054b544df6ceeb9e612d39af819f4aae, I added a hack to `ConstProp` that skips evaluating ZSTs to avoid that regression. This commit changes `SimplifyLocals` so that it doesn't consider writes of const values to a local to be a use of that local. In doing so, `SimplifyLocals` is able to remove otherwise unused locals left behind by other optimization passes (`ConstProp` in particular). 2019-08-19T21:31:46+00:00 sd234678 sd234678@protonmail.com 2019-08-19T21:31:46+00:00 urn:sha1:4eec03d33e0a833cb48998f5d8e47c01b9e32cf4 2019-07-06T04:43:58+00:00 Mazdak Farrokhzad twingoow@gmail.com 2019-06-24T02:27:20+00:00 urn:sha1:b9e7e3175a8ca6f7bbc09a5ae229d8962d94121f
