New documentation on coverage tests incorrectly assumed multiple test binaries could just be listed at the end of the `llvm-cov` command, but it turns out each binary needs a `--object` prefix. This PR fixes the bug and updates the documentation to correct that issue. It also fixes a few other minor issues in internal implementation comments, and adds documentation on getting coverage results for doc tests. 2020-12-03T17:50:10+00:00 Rich Kadel richkadel@google.com 2020-12-02T07:01:26+00:00 urn:sha1:d96f351fa36d31f2b95b1cd2ad37ceaed3d395a8 Added one more test (two files) showing coverage of generics and unused functions across crates. Created and referenced new Issues, as requested. Added comments. Added a note about the possible effects of compiler options on LLVM coverage maps. 2020-12-03T17:50:10+00:00 Rich Kadel richkadel@google.com 2020-12-01T07:58:08+00:00 urn:sha1:def932ca865b86a5057517d8a0e27c0ca72a0815 Fixes multiple issue with counters, with simplification Includes a change to the implicit else span in ast_lowering, so coverage of the implicit else no longer spans the `then` block. Adds coverage for unused closures and async function bodies. Fixes: #78542 Adding unreachable regions for known MIR missing from coverage map Cleaned up PR commits, and removed link-dead-code requirement and tests Coverage no longer depends on Issue #76038 (`-C link-dead-code` is no longer needed or enforced, so MSVC can use the same tests as Linux and MacOS now) Restrict adding unreachable regions to covered files Improved the code that adds coverage for uncalled functions (with MIR but not-codegenned) to avoid generating coverage in files not already included in the files with covered functions. Resolved last known issue requiring --emit llvm-ir workaround Fixed bugs in how unreachable code spans were added. 2020-11-13T00:22:25+00:00 Rich Kadel richkadel@google.com 2020-11-13T00:08:42+00:00 urn:sha1:c131063988ff8ac86bbf53a3bf998145c6b99d6f Restructured the code a little, to allow getting both the mir::Body and coverage graph. 2020-11-12T00:40:17+00:00 Rich Kadel richkadel@google.com 2020-11-03T05:32:48+00:00 urn:sha1:bd0eb07af2deaff2c9f1e7553ea97341787779cd As discussed in PR #78267, for example: * https://github.com/rust-lang/rust/pull/78267#discussion_r515404722 * https://github.com/rust-lang/rust/pull/78267#discussion_r515405958 2020-11-06T02:24:18+00:00 Rich Kadel richkadel@google.com 2020-10-30T23:09:05+00:00 urn:sha1:a7d956583ceae1487ad9b0748039bc9f0e8ac7aa 2020-11-06T02:24:17+00:00 Rich Kadel richkadel@google.com 2020-10-25T18:13:16+00:00 urn:sha1:1973f84ebbb3b2bb4b9a1488b6553ac46b2db8d4 2020-11-06T02:24:14+00:00 Rich Kadel richkadel@google.com 2020-10-23T03:28:16+00:00 urn:sha1:3291d28e9ac1173f033d240bc5f3f145c9c8dd59 2020-11-06T02:24:13+00:00 Rich Kadel richkadel@google.com 2020-10-23T06:11:38+00:00 urn:sha1:b5020648fe294a1f139586e4243903d8c1a105b8
