* [Fast-math] Disable "(C1/X)*C2 => (C1*C2)/X" if C1/X has multiple uses.Shuxin Yang2013-09-192-3/+18
| | | | | | | | | | | | | | | | | | | If "C1/X" were having multiple uses, the only benefit of this transformation is to potentially shorten critical path. But it is at the cost of instroducing additional div. The additional div may or may not incur cost depending on how div is implemented. If it is implemented using Newton–Raphson iteration, it dosen't seem to incur any cost (FIXME). However, if the div blocks the entire pipeline, that sounds to be pretty expensive. Let CodeGen to take care this transformation. This patch sees 6% on a benchmark. rdar://15032743 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191037 91177308-0d34-0410-b5e6-96231b3b80d8

* Unshift the GDB index/GNU pubnames constants modified in r191025David Blaikie2013-09-193-67/+56
| | | | | | | | | | | | Based on code review feedback from Eric Christopher, unshifting these constants as they can appear in the gdb_index itself, shifted a further 24 bits. This means that keeping them preshifted is a bit inflexible, so let's not do that. Given the motivation, wrap up some nicer enums, more type safety, and some utility functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191035 91177308-0d34-0410-b5e6-96231b3b80d8

* GVN proceeds in the presence of dead code.Shuxin Yang2013-09-199-28/+384
| | | | | | | | | | | | | | | | | | | | | | | This is how it ignores the dead code: 1) When a dead branch target, say block B, is identified, all the blocks dominated by B is dead as well. 2) The PHIs of those blocks in dominance-frontier(B) is updated such that the operands corresponding to dead predecessors are replaced by "UndefVal". Using lattice's jargon, the "UndefVal" is the "Top" in essence. Phi node like this "phi(v1 bb1, undef xx)" will be optimized into "v1" if v1 is constant, or v1 is an instruction which dominate this PHI node. 3) When analyzing the availability of a load L, all dead mem-ops which L depends on disguise as a load which evaluate exactly same value as L. 4) The dead mem-ops will be materialized as "UndefVal" during code motion. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191017 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | This puts all the global PassManager debugging flags, like -print-after-all and -time-passes, behind a managed static. This eliminates their static initializers and, more importantly, exit-time destructors. The only behavioral change I anticipate is that tools need to initialize the PassManager before parsing the command line in order to export these options, which makes sense. Tools that already initialize the standard passes (opt/llc) don't need to do anything new. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190974 91177308-0d34-0410-b5e6-96231b3b80d8
