Add switch aliases for compatibility with ldc2 and ldmd2 to dmd - #123
Merged
Conversation
Optimization-level switches as supported by more popular compilers as well as *GDC* or *LDC* are now accepted. As DMD does not actually implement support for multiple optimization levels, these switches merely turn the optimizer on or off. This streamlines the user experience to bring it in line with LDC's `ldmd2` wrapper. DMD will conditionally accept multiple differing optimization-level switches in one compiler invocation. This is as long as they do not effectively contradict each other with reference to the activation of the optimizer. The extent of switches supported by the implementation is intended to match GDC 14.2.
