¶std::unique_ptr<CompilerInvocation>
createInvocation(
    ArrayRef<const char*> Args,
    clang::CreateInvocationOptions Opts = {})

Description

Interpret clang arguments in preparation to parse a file. This simulates a number of steps Clang takes when its driver is invoked: - choosing actions (e.g compile + link) to run - probing the system for settings like standard library locations - spawning a cc1 subprocess to compile code, with more explicit arguments - in the cc1 process, assembling those arguments into a CompilerInvocation which is used to configure the parser This simulation is lossy, e.g. in some situations one driver run would result in multiple parses. (Multi-arch, CUDA, ...). This function tries to select a reasonable invocation that tools should use. Args[0] should be the driver name, such as "clang" or "/usr/bin/g++". Absolute path is preferred - this affects searching for system headers. May return nullptr if an invocation could not be determined. See CreateInvocationOptions::ShouldRecoverOnErrors to try harder!
