Author: atanasyan Date: Wed May 9 01:42:30 2018 New Revision: 331856 URL: http://llvm.org/viewvc/llvm-project?rev=331856&view=rev Log: [driver] Add mips_Features_Group to Options to improve documentation sorting
Move all of the MIPS-only options into a new m_mips_Features_Group. Nearly all other targets have most target-specific options grouped, but MIPS does not. The primary benefits are that the options will be listed together (and thus identifiable as MIPS-specific even if they have no help string) in the ClangCommandLineReference, and that Options.td is a bit more organized. A secondary benefit is that a custom version of clang can more easily hide/disable groups of options for unsupported targets.
