gribozavr added a comment.
What is the expected contract of the functions that this checker flags? Are
they supposed to perform unaligned reads correctly, and we have just an
implementation bug in these functions, or is it the caller's fault if they pass
an unaligned address?
================
Comment at: clang-tidy/objc/ObjCTidyModule.cpp:30
"objc-avoid-nserror-init");
+ CheckFactories.registerCheck<AvoidOSReadCheck>(
+ "objc-avoid-osread");
----------------
Maybe a better place for this checker is the new "darwin" module? It is being
added in https://reviews.llvm.org/D67567.
================
Comment at: test/clang-tidy/objc-avoid-osread.m:5
+ const char *buff = "";
+ OSReadBigInt(buff, 0);
+ // CHECK-MESSAGES: :[[@LINE-1]]:3: warning: use memcpy and
OSSwap{Big|Little}ToHostInt{16|32|64} instead of OSRead* calls to avoid
potential unaligned read issues [objc-avoid-osread]
----------------
Please add declarations for these functions. It is strange that this test even
works without them...
