Evan Cheng	5541068ad3	Run codegen dce pass for all targets at all optimization levels. Previously it's only run for x86 with fastisel. I've found it being very effective in eliminating some obvious dead code as result of formal parameter lowering especially when tail call optimization eliminated the need for some of the loads from fixed frame objects. It also shrinks a number of the tests. A couple of tests no longer make sense and are now eliminated. llvm-svn: 95493	2010-02-06 09:07:11 +00:00

Run codegen dce pass for all targets at all optimization levels. Previously it's

only run for x86 with fastisel. I've found it being very effective in
eliminating some obvious dead code as result of formal parameter lowering
especially when tail call optimization eliminated the need for some of the loads
from fixed frame objects. It also shrinks a number of the tests. A couple of
tests no longer make sense and are now eliminated.
