Alex Crichton 2f3fde60c3 Implement an address_insignificant attribute ... This can be applied to statics and it will indicate that LLVM will attempt to merge the constant in .data with other statics. I have preliminarily applied this to all of the statics generated by the new `ifmt!` syntax extension. I compiled a file with 1000 calls to `ifmt!` and a separate file with 1000 calls to `fmt!` to compare the sizes, and the results were: fmt 310k ifmt (before) 529k ifmt (after) 202k This now means that ifmt! is both faster and smaller than fmt!, yay!		2013-08-09 13:49:41 -07:00
