Add /Zc:DllexportInlines option to clang-cl Summary: This CL adds /Zc:DllexportInlines flag to clang-cl. When Zc:DllexportInlines- is specified, inline class member function is not exported if the function does not have local static variables. By not exporting inline function, code for those functions are not generated and that reduces both compile time and obj size. Also this flag does not import inline functions from dllimported class if the function does not have local static variables.

clang-cl: Add "/clang:" pass-through arg support. The clang-cl driver disables access to command line options outside of the "Core" and "CLOption" sets of command line arguments. This filtering makes it impossible to pass arguments that are interpreted by the clang driver and not by either 'cc1' (the frontend) or one of the other tools invoked by the driver. An example driver-level flag is the '-fno-slp-vectorize' flag, which is processed by the driver in Clang::ConstructJob and used to set the cc1 flag "-vectorize-slp". There is no negative cc1 flag or -mllvm flag, so it is not currently possible to disable the SLP vectorizer from the clang-cl driver. This change introduces the "/clang:" argument that is available when the driver mode is set to CL compatibility. This option works similarly to the "-Xclang" option, except that the option values are processed by the clang driver rather than by 'cc1'. An example usage is: clang-cl /clang:-fno-slp-vectorize /O2 test.c Another example shows how "/clang:" can be used to pass a flag where there is a conflict between a clang-cl compat option and an overlapping clang driver option: clang-cl /MD /clang:-MD /clang:-MF /clang:test_dep_file.dep test.c In the previous example, the unprefixed /MD selects the DLL version of the msvc CRT, while the prefixed -MD flag and the -MF flags are used to create a make dependency file for included headers. One note about flag ordering: the /clang: flags are concatenated to the end of the argument list, so in cases where the last flag wins, the /clang: flags will be chosen regardless of their order relative to other flags on the driver command line.
