2020-04-17Minor fix and addition to doc commentsJOE1994-0/+1
1. Fixed doc comment of struct 'rustc_middle::mir::Location' Currently, the general explanation of the struct appears at the field explanation section. I moved and changed the doc comments slightly, so that the general explanation would appear in the proper location in docs. 2. Added doc comment explaining 'rustc_mir::util::pretty::write_mir_fn' Unlike other counterparts, brief explanation for this function was missing, so I added one. Thank you for reviewing this PR :)

2020-04-01Rollup merge of #70511 - ecstatic-morse:mir-dataflow-graphviz, r=davidtwcoMazdak Farrokhzad-4/+4
Add `-Z dump-mir-dataflow` flag for dumping dataflow results visualization Previously, to visualize the results of a MIR dataflow pass, one had to add a `#[rustc_mir(borrowck_graphviz_postflow)]` attribute to functions of interest. However, there is no way to specify this attribute on closures and generators, so it was impossible to view results for these MIR bodies. This PR adds a flag, `-Z dump-mir-dataflow`, which will output the dataflow results for any functions specified in `-Z dump-mir` to the output directory specified by `-Z dump-mir-dir`. This behavior is modeled on the `-Z dump-mir-graphviz` flag.

2020-03-01Auto merge of #68943 - ecstatic-morse:no-useless-drop-on-enum-variants, ↵bors-15/+30
r=matthewjasper Skip `Drop` terminators for enum variants without drop glue Split out from #68528. When doing drop elaboration for an `enum` that may or may not be moved out of (an open drop), we check the discriminant of the `enum` to see whether the live variant has any drop flags and then check the drop flags to see whether we need to drop each field. Sometimes, however, the live variant has no move paths and thus no drop flags. In this case, we still emit a drop terminator for the entire enum after checking the enum discriminant. This drop shim will check the discriminant of the enum *again* and then drop the fields of the active variant. If the active variant has no drop glue, nothing will be done. This commit skips emitting the drop terminator during drop elaboration when the "otherwise" variants, those without move paths, have no drop glue. A common example of this scenario is when an `Option` is moved from, since `Option::None` never needs drop glue. Below is a fragment the pre-codegen CFG for `Option::unwrap_or` in which we check the drop flag (`_5`) for `self` (`_1`), before and after the change. Before: ![image](https://user-images.githubusercontent.com/29463364/74078927-52942380-49e5-11ea-8e34-4b9d6d94ef25.png) After: ![image](https://user-images.githubusercontent.com/29463364/74078945-78b9c380-49e5-11ea-8302-b043c4a7515a.png) This change doesn't do much on its own, but it is a prerequisite to get the perf gains from #68528. cc @arielb1
