Duncan Sands 3f329cb781 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141360 91177308-0d34-0410-b5e6-96231b3b80d8		2011-10-07 08:29:06 +00:00
