2025-06-08[llvm] Compare std::optional<T> to values directly (NFC) (#143340)Kazu Hirata1-2/+2
This patch transforms: X && *X == Y to: X == Y where X is of std::optional<T>, and Y is of T or similar.
2024-12-27llvm-cov: Introduce `--binary-counters` (#120841)NAKAMURA Takumi1-3/+3
In `llvm-cov show`, this option rounds counters (line, branch) to `[1,0]` at rendering. This will be useful when the number of counts doesn't interest but **Covered/uncoverd** does.
2024-12-18llvm-cov: Refactor SourceCoverageView::renderBranchView().NAKAMURA Takumi1-37/+28
NFC except for calculating `Total`. I've replaced `(uint64_t)+(uint64_t)` with `(double)+(double)`. This is still inexact with large numbers `(1LL << 53)` but will be expected to prevent possible overflow.
2024-10-20[Coverage] Introduce "partial fold" on BranchRegion (#112694)NAKAMURA Takumi1-20/+27
Currently both True/False counts were folded. It lost the information, "It is True or False before folding." It prevented recalling branch counts in merging template instantiations. In `llvm-cov`, a folded branch is shown as: - `[True: n, Folded]` - `[Folded, False n]` In the case If `n` is zero, a branch is reported as "uncovered". This is distinguished from "folded" branch. When folded branches are merged, `Folded` may be dissolved. In the coverage map, either `Counter` is `Zero`. Currently both were `Zero`. Since "partial fold" has been introduced, either case in `switch` is omitted as `Folded`. Each `case:` in `switch` is reported as `[True: n, Folded]`, since `False` count doesn't show meaningful value. When `switch` doesn't have `default:`, `switch (Cond)` is reported as `[Folded, False: n]`, since `True` count was just the sum of `case`(s). `switch` with `default` can be considered as "the statement that doesn't have any `False`(s)".

2023-08-24[llvm-cov] Support directory layout in coverage reportsYuhao Gu1-0/+65
This is a GSoC 2023 project ([discourse link](https://discourse.llvm.org/t/coverage-support-a-hierarchical-directory-structure-in-generated-coverage-html-reports/68239)). llvm-cov currently generates a single top-level index HTML file, which causes rendering scalability issues in large projects. This patch adds support for hierarchical directory structure into the HTML reports to solve scalability issues by introducing the following changes: - Added a new command line option `--show-directory-coverage` for `llvm-cov show`. It works both for `--format=html` and `--format=text`. - Two new classes: `CoveragePrinterHTMLDirectory` and `CoveragePrinterTextDirectory` was added to support the new option. - A tool class `DirectoryCoverageReport` was added to support the two classes above. - Updated the document. - Added a new regression test for `--show-directory-coverage`.

2021-01-05[Coverage] Add support for Branch Coverage in LLVM Source-Based Code CoverageAlan Phipps1-1/+49
This is an enhancement to LLVM Source-Based Code Coverage in clang to track how many times individual branch-generating conditions are taken (evaluate to TRUE) and not taken (evaluate to FALSE). Individual conditions may comprise larger boolean expressions using boolean logical operators. This functionality is very similar to what is supported by GCOV except that it is very closely anchored to the ASTs. Differential Revision: https://reviews.llvm.org/D84467

2019-08-02Improve raw_ostream so that you can "write" colors using operator<<Rui Ueyama1-1/+1
1. raw_ostream supports ANSI colors so that you can write messages to the termina with colors. Previously, in order to change and reset color, you had to call `changeColor` and `resetColor` functions, respectively. So, if you print out "error: " in red, for example, you had to do something like this: OS.changeColor(raw_ostream::RED); OS << "error: "; OS.resetColor(); With this patch, you can write the same code as follows: OS << raw_ostream::RED << "error: " << raw_ostream::RESET; 2. Add a boolean flag to raw_ostream so that you can disable colored output. If you disable colors, changeColor, operator<<(Color), resetColor and other color-related functions have no effect. Most LLVM tools automatically prints out messages using colors, and you can disable it by passing a flag such as `--disable-colors`. This new flag makes it easy to write code that works that way.

2019-01-19Update the file headers across all of the LLVM projects in the monorepoChandler Carruth1-4/+3
to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

2017-11-09[Coverage] Use the wrapped segment when a line has entry segmentsVedant Kumar1-5/+6
We've worked around bugs in the frontend by ignoring the count from wrapped segments when a line has at least one region entry segment. Those frontend bugs are now fixed, so it's time to regenerate the checked-in covmapping files and remove the workaround. llvm-svn: 317761

2017-10-18[llvm-cov] Suppress sub-line highlights in simple casesVedant Kumar1-0/+2
llvm-cov tends to highlight too many regions because its policy is to highlight all region entry segments. This can look confusing to users: not all region entry segments are interesting and deserve highlighting. Emitting these highlights only when the region count differs from the line count is a more user-friendly policy. llvm-svn: 316109
2017-10-18[llvm-cov] Pass LineCoverageStats in SourceCoverageView. NFC.Vedant Kumar1-10/+16
Instead of copying around the wrapped segment and the list of line segments, just pass a reference to a LineCoverageStats object. This simplifies the interface. It also makes an upcoming change to suppress distracting highlights possible. llvm-svn: 316108
2017-10-18[llvm-cov] Highlight gaps in consecutive uncovered regionsVedant Kumar1-1/+2

There were two copies of the logic needed to construct a line stats object for each line in a range: this patch brings it down to one. In the future, this will make it easier for IDE clients to display coverage in-line in source editors. To do that, we just need to move the new LineCoverageIterator class to libCoverage. llvm-svn: 315789

2017-09-18[Coverage] Use gap regions to select better line exec countsVedant Kumar1-1/+1
After clang started emitting deferred regions (r312818), llvm-cov has had a hard time picking reasonable line execuction counts. There have been one or two generic improvements in this area (e.g r310012), but line counts can still report coverage for whitespace instead of code (llvm.org/PR34612). To fix the problem: * Introduce a new region kind so that frontends can explicitly label gap areas. This is done by changing the encoding of the columnEnd field of MappingRegion. This doesn't substantially increase binary size, and makes it easy to maintain backwards-compatibility. * Don't set the line count to a count from a gap area, unless the count comes from a wrapped segment. * Don't highlight gap areas as uncovered. Fixes llvm.org/PR34612. llvm-svn: 313597

2016-10-25[llvm-cov] Do not print out the filename of the object fileVedant Kumar1-2/+2
When we load coverage data from multiple objects, we don't have a way to attribute a source object to a function record. Printing out the object filename next to the source filename is already not very useful: soon, it'll actually become misleading. Stop printing out the filename now. llvm-svn: 285043
2016-09-23[llvm-cov] Get rid of all invalid filename referencesVedant Kumar1-2/+2
We used to append filenames into a vector of std::string, and then append a reference to each string into a separate vector. This made it easier to work with the getUniqueSourceFiles API. But it's buggy. std::string has a small-string optimization, so you can't expect to capture a reference to one if you're copying it into a growing vector. Add a test that triggers this invalid reference to std::string scenario, and kill the issue with fire by just using ArrayRef<std::string> everywhere. llvm-svn: 282281
2016-09-15[llvm-cov] Hide instantiation views for unexecuted functionsVedant Kumar1-1/+6
