Bug ID: 43808
Summary: Improve -Wdocumentation fix-it suggestion for multiple
errors
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: l...@alex.lanin.de
CC: llvm-bugs@lists.llvm.org, neeil...@live.com,

Given two different mismatches of documentation and code:
/**
* @param[in] arg[] Docu_1
* @param[in] cnt Docu_2
*/
void run(const char* const arg[], int argc);
When compiling with -Weverything:
test.cpp:2:17: warning: parameter 'arg[]' not found in the function
declaration [-Wdocumentation]
* @param[in] arg[] Docu_1
^~~~~
test.cpp:2:17: note: did you mean 'argc'?
* @param[in] arg[] Docu_1
^~~~~
argc
test.cpp:3:17: warning: parameter 'cnt' not found in the function
declaration [-Wdocumentation]
* @param[in] cnt Docu_2
^~~
So the clang-tidy fix-it doesn't really improve the situation:
/**
* @param[in] argc Docu_1
* @param[in] cnt Docu_2
*/
void run(const char* const arg[], int argc);
Expected behavior:
1) arg[] should be replaced by "arg" and not "argc" as it's more similar.
2) Consequently cnt would be replaced by argc as that would be the only
possibility after (1). I guess this will work out of the box after (1).
