561f0de6 - [analyzer] Increase minimum complexity filter of the CloneChecker.

Mon, 04 Sep 2017 05:56:36 +0000

[analyzer] Increase minimum complexity filter of the CloneChecker.Summary:So far we used a value of 10 which was useful for testing but produces many false-positives in real programs. The usual suspicious clones we find seem to be at around a complexity value of 70 and for normal clone-reporting everything above 50 seems to be a valid normal clone for users, so let's just go with 50 for now and set this as the new default value.This patch also explicitly sets the complexity value for the regression tests as they serve more of a regression testing/debugging purpose and shouldn't really be reported by default in real programs. I'll add more tests that reflect actual found bugs that then need to pass with the default setting in the future.Reviewers: NoQSubscribers: cfe-commits, javed.absar, xazax.hun, v.g.vassilevDifferential Revision: https://reviews.llvm.org/D34178llvm-svn: 312468 List of files: /llvm-project-15.0.7/clang/test/Analysis/copypaste/functions.cpp

Mon, 03 Oct 2016 08:11:50 +0000

[analyzer] Improve CloneChecker diagnosticsHighlight code clones referenced by the warning message with the help ofthe extra notes feature recently introduced in r283092.Change warning text to more clang-ish. Remove suggestions from the copy-pasteerror checker diagnostics, because currently our suggestions are strictly 50%wrong (we do not know which of the two code clones contains the error), andfor that reason we should not sound as if we're actually suggesting this.Hopefully a better solution would bring them back.Make sure the suspicious clone pair structure always mentionsthe correct variable for the second clone.Differential Revision: https://reviews.llvm.org/D24916llvm-svn: 283094 List of files: /llvm-project-15.0.7/clang/test/Analysis/copypaste/functions.cpp

7a0088bb - [analyzer] Make CloneDetector recognize different variable patterns.

Thu, 04 Aug 2016 19:37:00 +0000

[analyzer] Make CloneDetector recognize different variable patterns.CloneDetector should be able to detect clones with renamed variables.However, if variables are referenced multiple times around the code sample,the usage patterns need to be recognized.For example, (x < y ? y : x) and (y < x ? y : x) are no longer clones,however (a < b ? b : a) is still a clone of the former.Variable patterns are computed and compared during a separate filtering pass.Patch by Raphael Isemann!Differential Revision: https://reviews.llvm.org/D22982llvm-svn: 277757 List of files: /llvm-project-15.0.7/clang/test/Analysis/copypaste/functions.cpp

78692ea5 - [analyzer] Respect statement-specific data in CloneDetection.

Tue, 02 Aug 2016 12:21:09 +0000

[analyzer] Respect statement-specific data in CloneDetection.So far the CloneDetector only respected the kind of each statement whensearching for clones. This patch refines the way the CloneDetector collects datafrom each statement by providing methods for each statement kind,that will read the kind-specific attributes.For example, statements 'a < b' and 'a > b' are no longer considered to beclones, because they are different in operation code, which is an attributespecific to the BinaryOperator statement kind.Patch by Raphael Isemann!Differential Revision: https://reviews.llvm.org/D22514llvm-svn: 277449 List of files: /llvm-project-15.0.7/clang/test/Analysis/copypaste/functions.cpp

ba816326 - [analyzer] Add basic capabilities to detect source code clones.

Tue, 26 Jul 2016 18:13:12 +0000

[analyzer] Add basic capabilities to detect source code clones.This patch adds the CloneDetector class which allows searching source codefor clones.For every statement or group of statements within a compound statement,CloneDetector computes a hash value, and finds clones by detectingidentical hash values.This initial patch only provides a simple hashing mechanismthat hashes the kind of each sub-statement.This patch also adds CloneChecker - a simple static analyzer checkerthat uses CloneDetector to report copy-pasted code.Patch by Raphael Isemann!Differential Revision: https://reviews.llvm.org/D20795llvm-svn: 276782 List of files: /llvm-project-15.0.7/clang/test/Analysis/copypaste/functions.cpp
