* [clang-tidy] Don't warn implicit variables in ↵Haojian Wu2016-11-081-0/+19
| | | | | | | | | | | | | | | | | | | peformance-unnecessary-copy-initialization. Summary: This will prevent the check warning the variables which have been implicitly added by compiler, like the following case (in for-range loop): the variable '__end' is copy-constructed from a const reference...

* [clang-tidy] UnnecessaryCopyInitialization - Extend to trigger on non-const ↵Felix Berger2016-05-311-33/+56
| | | | | | | | | | | | | | | | | | | | | | | | | "this" object argument if it is not modified. Summary: Also trigger the check in the following case: void foo() { ExpensiveToCopy Obj; const auto UnnecessaryCopy = Obj.constReference(); Obj.onlyUsedAsConst(); } i.e. when the object the method is called on is not const but is never modified.

| | | | | | | | | | | | | | Summary: Extends the UnnecessaryCopyInitialization to detect copies of local variables and parameters that are unneeded. Patch by Matt Kulukundis! Reviewers: alexfh, hokein Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D18149 llvm-svn: 264146

| | | | | | | | | | | | | | | | non-const copies that can be safely converted to const references. Summary: Move code shared between UnnecessaryCopyInitialization and ForRangeCopyCheck into utilities files. Add more test cases for UnnecessaryCopyInitialization and disable fixes inside of macros.

* [clang-tidy] Use hasLocalStorage() to identify unnecessary copy ↵Alexander Kornienko2015-12-301-0/+4
| | | | | | | | | | | | | | initializations to exclude static local variables. Summary: Since local static variables can outlive other local variables exclude them from the unnecessary copy initialization check. Reviewers: alexfh Patch by Felix Berger!

* [clang-tidy] Add UnnecessaryCopyInitialization check to new "performance" ↵Alexander Kornienko2015-12-301-0/+152
module in ClangTidy Summary: The patch adds a new ClangTidy check that detects when expensive-to-copy types are unnecessarily copy initialized from a const reference that has the same or are larger scope than the copy. It currently only detects this when the copied variable is const qualified. But this will be extended to non const variables if they are only used in a const fashion.
