Also add some more comments. I was worried about compile time impacts and did not implement reachability but used the dominance check in the initial patch. The trade-off was that the dominator tree was required. The llvm utility function isPotentiallyReachable cuts off the recursive search after 32 visits.

When converting a signed 32-bit integer to double-precision floating point on hardware without a lfiwax instruction, we have to instead use a lfd followed by fcfid. We were erroneously offsetting the address by 4 bytes in preparation for either a lfiwax or lfiwzx when generating the lfd. This fixes that silly error. This was not caught in the test suite since the conversion tests were run with -mcpu=pwr7, which implies availability of lfiwax. I've added another test case for older hardware that checks the code we expect in the absence of lfiwax and other flavors of fcfid. There are fewer tests in this test case because we punt to DAG selection in more cases on older hardware. (We must generate complex fiddly sequences in those cases, and there is marginal benefit in duplicating that logic in fast-isel.) ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@205824 91177308-0d34-0410-b5e6-96231b3b80d8

When the loop had a non-constant lower bound, the SCEV expander would end the code expansion with an add insted of a phi node and the cast would fail. It looks like the cast to a phi node was only needed to get the induction variable value coming from the backedge to compute the end of loop condition. This patch changes the loop reroller to compare the induction variable to the number of times the backedge is taken instead of the iteration count of the loop. In other words, we stop the loop when the current value of the induction variable == IterationCount-1. Previously, the comparison was comparing the induction variable value from the next iteration == IterationCount. This problem only seems to occur on 32-bit targets. For some reason, the loop is not rerolled on 64-bit targets.

Issue outcomes from DAGCombiner::MergeConsequtiveStores, more precisely from mem-ops sequence sorting. Consider, how MergeConsequtiveStores works for next example: store i8 1, a[0] store i8 2, a[1] store i8 3, a[1] ; a[1] again. return ; DAG starts here 1. Method will collect all the 3 stores. 2. It sorts them by distance from the base pointer (farthest with highest index). 3. It takes first consecutive non-overlapping stores and (if possible) replaces them with a single store instruction. The point is, we can't determine here which 'store' instruction would be the second after sorting ('store 2' or 'store 3'). It happens that 'store 3' would be the second, and 'store 2' would be the third. So after merging we have the next result: store i16 (1 | 3 << 8), base ; is a[0] but bit-casted to i16 store i8 2, a[1] So actually we swapped 'store 3' and 'store 2' and got wrong contents in a[1].

The inline cost analysis inheritted some pretty rough handling of terminator insts from the original cost analysis, and then made it much, much worse by factoring all of the important analyses into a separate instruction visitor. That instruction visitor never visited the terminator. This works fine for things like conditional branches, but for many other things we simply computed The Wrong Value. First example are unconditional branches, which should be free but were counted as full cost. This is most significant for conditional branches where the condition simplifies and folds during inlining. We paid a 1 instruction tax on every branch in a straight line specialized path. =[ Oh, we also claimed that the unreachable instruction had cost. But it gets worse. Let's consider invoke. We never applied the call penalty. We never accounted for the cost of the arguments. Nope. Worse still, we didn't handle the *correctness* constraints of not inlining recursive invokes, or exception throwing returns_twice functions. Oops. See PR18206. Sadly, PR18206 requires yet another fix, but this refactoring is at least a huge step in that direction. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@197351 91177308-0d34-0410-b5e6-96231b3b80d8
