annotate dmd/mars.h @ 1052:12ea38902e83
Add '-singleobj' command line switch that will tell LDC to link LLVM modules internally and only emit a single object file.
The switch allows the optimizer and inliner to run on all modules at once and opens the door for template instantiation improvements that should lower compile time and executable size.

Changed templates and typeinfo to use linkonce linkage instead of weak linkage, this should fix inlining problems, fixing bug #197 . If problems show up, it's easy to change it back by changing the define in mars.h . I'm 95% sure this is safe, given how we handle templates.
