Renato Golin 07d9471bc5 Add #pragma vectorize enable/disable to LLVM ... The intended behaviour is to force vectorization on the presence of the flag (either turn on or off), and to continue the behaviour as expected in its absence. Tests were added to make sure the all cases are covered in opt. No tests were added in other tools with the assumption that they should use the PassManagerBuilder in the same way. This patch also removes the outdated -late-vectorize flag, which was on by default and not helping much. The pragma metadata is being attached to the same place as other loop metadata, but nothing forbids one from attaching it to a function (to enable #pragma optimize) or basic blocks (to hint the basic-block vectorizers), etc. The logic should be the same all around. Patches to Clang to produce the metadata will be produced after the initial implementation is agreed upon and committed. Patches to other vectorizers (such as SLP and BB) will be added once we're happy with the pass manager changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196537 91177308-0d34-0410-b5e6-96231b3b80d8		2013-12-05 21:20:02 +00:00
