1) In my P.C. gcc version 4.1.2 has been installed. I have a look at http://gcc.gnu.org/. In that it is said that 4.1.2 is the "current release series", "Next release series: GCC 4.2.0" and "Active development: GCC 4.3.0" What does it mean? Has gcc 4.2.0/4.3.0 been released??? If so from where can I download 4.2/4.3????? 2)From which version "auto-vectorization" has been included? In http://gcc.gnu.org/projects/tree-ssa/vectorization.html#status4.0 it is said that gcc 4.0 also does "auto-vectorization". Deos it mean auto-vectorization cababilities of gcc4.0 and gcc4.1/4.2 are same?? 3)-ftree-vectorize is the flag that enables autovectorization. isn't it?? 4) where can I get C programs for which gcc can do autovectorization and for which it cant? 4) I know all languages are internallay converted to same representation(in the context of gcc compiler). So what is said in gcc manuals about auto-vectorization is applicable to all languages gcc supports. Isn't it?
