Duncan Sands 559ef2f491 Teach GVN to also propagate switch cases. For example, in this code ... switch (n) { case 27: do_something(x); ... } the call do_something(x) will be replaced with do_something(27). In gcc-as-one-big-file this results in the removal of about 500 lines of bitcode (about 0.02%), so has about 1/10 of the effect of propagating branch conditions. llvm-svn: 141360		2011-10-07 08:29:06 +00:00
