GetArgumentVector (or GetCommandLineArguments) is very Windows-specific. I think it doesn't make much sense to provide that function from sys::Process. I also made a change so that the function takes a BumpPtrAllocator instead of a SpecificBumpPtrAllocator. The latter is the class to call dtors, but since char * is trivially destructible, we should use the former class. Differential Revision: https://reviews.llvm.org/D45641 llvm-svn: 330216

// The main() functions in typical LLVM tools start with InitLLVM which does
|
|
// the following one-time initializations:
|
|
//
|
|
// 1. Setting up a signal handler so that pretty stack trace is printed out
|
|
// if a process crashes.
|
|
//
|
|
// 2. If running on Windows, obtain command line arguments using a
|
|
// multibyte character-aware API and convert arguments into UTF-8
|
|
// encoding, so that you can assume that command line arguments are
|
|
// always encoded in UTF-8 on any platform.
|
|
//
|
|
// InitLLVM calls llvm_shutdown() on destruction, which cleans up
|
|
// ManagedStatic objects.
