; All test functions do the same thing - they return the first variable
; argument.
Recommit r129383. PreRA scheduler heuristic fixes: VRegCycle, TokenFactor latency. Additional fixes: Do something reasonable for subtargets with generic itineraries by handle node latency the same as for an empty itinerary. Now nodes default to unit latency unless an itinerary explicitly specifies a zero cycle stage or it is a TokenFactor chain. Original fixes: UnitsSharePred was a source of randomness in the scheduler: node priority depended on the queue data structure. I rewrote the recent VRegCycle heuristics to completely replace the old heuristic without any randomness. To make the ndoe latency adjustments work, I also needed to do something a little more reasonable with TokenFactor. I gave it zero latency to its consumers and always schedule it as low as possible. llvm-svn: 129421

In visitSTORE, always use FindBetterChain, rather than only when UseAA is enabled. Recommiting with compiler time improvements Recommitting after fixup of 32-bit aliasing sign offset bug in DAGCombiner. * Simplify Consecutive Merge Store Candidate Search Now that address aliasing is much less conservative, push through simplified store merging search and chain alias analysis which only checks for parallel stores through the chain subgraph. This is cleaner as the separation of non-interfering loads/stores from the store-merging logic. When merging stores search up the chain through a single load, and finds all possible stores by looking down from through a load and a TokenFactor to all stores visited. This improves the quality of the output SelectionDAG and the output Codegen (save perhaps for some ARM cases where we correctly constructs wider loads, but then promotes them to float operations which appear but requires more expensive constant generation). Some minor peephole optimizations to deal with improved SubDAG shapes (listed below) Additional Minor Changes: 1. Finishes removing unused AliasLoad code 2. Unifies the chain aggregation in the merged stores across code paths 3. Re-add the Store node to the worklist after calling SimplifyDemandedBits. 4. Increase GatherAllAliasesMaxDepth from 6 to 18. That number is arbitrary, but seems sufficient to not cause regressions in tests. 5. Remove Chain dependencies of Memory operations on CopyfromReg nodes as these are captured by data dependence 6. Forward loads-store values through tokenfactors containing {CopyToReg,CopyFromReg} Values. 7. Peephole to convert buildvector of extract_vector_elt to extract_subvector if possible (see CodeGen/AArch64/store-merge.ll) 8. Store merging for the ARM target is restricted to 32-bit as some in some contexts invalid 64-bit operations are being generated. This can be removed once appropriate checks are added. This finishes the change Matt Arsenault started in r246307 and jyknight's original patch. Many tests required some changes as memory operations are now reorderable, improving load-store forwarding. One test in particular is worth noting: CodeGen/PowerPC/ppc64-align-long-double.ll - Improved load-store forwarding converts a load-store pair into a parallel store and a memory-realized bitcast of the same value. However, because we lose the sharing of the explicit and implicit store values we must create another local store. A similar transformation happens before SelectionDAG as well.

; CHECK-LABEL: va9:
Elide argument copies during instruction selection Summary: Avoids tons of prologue boilerplate when arguments are passed in memory and left in memory. This can happen in a debug build or in a release build when an argument alloca is escaped. This will dramatically affect the code size of x86 debug builds, because X86 fast isel doesn't handle arguments passed in memory at all. It only handles the x86_64 case of up to 6 basic register parameters. This is implemented by analyzing the entry block before ISel to identify copy elision candidates. A copy elision candidate is an argument that is used to fully initialize an alloca before any other possibly escaping uses of that alloca. If an argument is a copy elision candidate, we set a flag on the InputArg. If the the target generates loads from a fixed stack object that matches the size and alignment requirements of the alloca, the SelectionDAG builder will delete the stack object created for the alloca and replace it with the fixed stack object. The load is left behind to satisfy any remaining uses of the argument value. The store is now dead and is therefore elided. The fixed stack object is also marked as mutable, as it may now be modified by the user, and it would be invalid to rematerialize the initial load from it.
