2020-04-27Change return type of `entry_fn` query to return a `LocalDefId`marmeladema-1/+1
2020-04-14Update the minimum external LLVM to 8Josh Stone-15/+3
LLVM 8 was released on March 20, 2019, over a year ago.
2020-04-05Fix performance regression in debuginfo file_metadata.Arlo Siemsen-11/+10
Finding the `SourceFile` associated with a `FileName` called `get_source_file` on the `SourceMap`, which does a linear search through all files in the `SourceMap`. This resolves the issue by passing the SourceFile in from the caller (which already had it available).
2020-04-02Add hash of source files in debug infoArlo Siemsen-3/+31
* Adds either an MD5 or SHA1 hash to the debug info. * Adds new unstable option `-Z src-hash-algorithm` to control the hashing algorithm.

2020-03-23Rollup merge of #69968 - eddyb:tupled-closure-captures, r=nikomatsakisMazdak Farrokhzad-2/+2
rustc: keep upvars tupled in {Closure,Generator}Substs. Previously, each closure/generator capture's (aka "upvar") type was tracked as one "synthetic" type parameter in the closure/generator substs, and figuring out where the parent `fn`'s generics end and the synthetics start involved slicing at `tcx.generics_of(def_id).parent_count`. Needing to query `generics_of` limited @davidtwco (who wants to compute some `TypeFlags` differently for parent generics vs upvars, and `TyCtxt` is not available there), which is how I got started on this, but it's also possible that the `generics_of` queries are slowing down `{Closure,Generator}Substs` methods. To give an example, for a `foo::<T, U>::{closure#0}` with captures `x: X` and `y: Y`, substs are: * before this PR: `[T, U, /*kind*/, /*signature*/, X, Y]` * after this PR: `[T, U, /*kind*/, /*signature*/, (X, Y)]` You can see that, with this PR, no matter how many captures, the last 3 entries in the substs (or 5 for a generator) are always the "synthetic" ones, with the last one being the tuple of capture types. r? @nikomatsakis cc @Zoxc

Emit 1-based column numbers in debuginfo * Use byte offsets instead of char position offsets. Resolves #67360. * Use 1-based offsets instead of 0-based ones. Resolves #65437. * Consistently omit column information for msvc targets, matching clang behaviour (previously columns have been omitted from `DILocation`, but not from `DILexicalBlock`).

2020-02-09Rollup merge of #68881 - eddyb:always-preserve-dbg-vars, r=nagisaJonas Schievink-1/+1
rustc_codegen_llvm: always set AlwaysPreserve on all debuginfo variables Making this depend on the optimization level appears to have been a copy-paste mistake (other LLVM functions called in this module also take a `bool` argument, but there it means something unrelated). Also see https://github.com/rust-lang/rust/pull/8855#discussion_r374392128. I don't believe we have any reason to let LLVM omit user variables from DWARF, and we were already setting this to `true` when LLVM *could* optimize them away, so this PR should have no effect anyway. r? @michaelwoerister or @nagisa cc @hanna-kruppe @nikomatsakis
