Chris Lattner	b0bf058d33	The smallvector dtor should destroy the elements. ... Implement pop_back. Chage some code to use 'iterator' instead of T*. This unbreaks operators=. llvm-svn: 29380	2006-07-28 05:03:42 +00:00
Chris Lattner	f2d0e0296a	Use std::copy instead of custom loops to take advantage of STL optimizations. ... Add a new append method for appending a range. llvm-svn: 29323	2006-07-27 03:38:08 +00:00
Chris Lattner	d4d69f64dd	Add a new llvm::SmallVector template, which is similar to the vector class, but ... contains optimizations to avoid heap allocation if the vector size is smaller than some threshold. This can significantly improve the performance of code that allocates many small vectors by eliminating tons of small malloc/free's. llvm-svn: 29281	2006-07-26 06:22:30 +00:00
