Comment (by mouse07410):

 OK, you're probably right. I can only say that I have never used {{{scan-
 build}}}, and the one time I tried - it did not work properly.

 P.S. Though this message from it is correct:
 {{{
 scan-build: Using '/opt/local/libexec/llvm-12/bin/clang' for static
 analysis
 Using testing flags: -std=gnu++17 -O3 -march=native -isysroot
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk
 Running make again to see what failed
 TestPrograms/test_x86_sse2.cpp:5:5: warning: Value stored to 'x' is never
 read [deadcode.DeadStores]
     x=_mm_add_epi64(x,x);
     ^ ~~~~~~~~~~~~~~~~~~
 1 warning generated.
 }}}
