Adam Balogh	0857ca489e	[clang-tidy] Add support for operator new[] in check bugprone-misplaced-operator-in-strlen-in-alloc The check now recognizes error cases like `new char[strlen(s + 1)]` and suggests a fix in the format `new char[strlen(s) + 1]`. llvm-svn: 318912	2017-11-23 12:56:23 +00:00
Adam Balogh	4c488975da	[clang-tidy] Misplaced Operator in Strlen in Alloc A possible error is to write `malloc(strlen(s+1))` instead of `malloc(strlen(s)+1)`. Unfortunately the former is also valid syntactically, but allocates less memory by two bytes (if `s` is at least one character long, undefined behavior otherwise) which may result in overflow cases. This check detects such cases and also suggests the fix for them. Fix for r318906, forgot to add new files. llvm-svn: 318907	2017-11-23 12:33:12 +00:00

[clang-tidy] Add support for operator new[] in check bugprone-misplaced-operator-in-strlen-in-alloc

The check now recognizes error cases like `new char[strlen(s + 1)]` and suggests
a fix in the format `new char[strlen(s) + 1]`.

[clang-tidy] Misplaced Operator in Strlen in Alloc

A possible error is to write `malloc(strlen(s+1))` instead of
`malloc(strlen(s)+1)`. Unfortunately the former is also valid syntactically,
but allocates less memory by two bytes (if `s` is at least one character long,
undefined behavior otherwise) which may result in overflow cases. This check
detects such cases and also suggests the fix for them.

Fix for r318906, forgot to add new files.
