[cfe-dev] Help required to use clang analyzer

[Artem Dergachev via cfe-dev]

Hi,

Using -cc1 disables the clang Driver. The Driver is responsible for gcc 
compatibility, which, apart from being able to translate gcc flags to 
clang flags, adds support for finding system headers in places where gcc 
usually looks for them. There are other drivers, such as clang-cl which 
turns clang into a drop-in replacement for the Visual Studio's cl.exe.

Running without the driver is not recommended for everyday use, only for 
development of clang itself.

If you want to run the Static Analyzer on a single file, you can do

     clang --analyze test.c

But even better, you should use the scan-build tool to analyze the 
entire project, for example:

     scan-build clang test.c

or

     scan-build gcc test.c

or

     scan-build make -j4

etc. See https://clang-analyzer.llvm.org/scan-build.html for more details.
