* Sort the remaining #include lines in include/... and lib/....Chandler Carruth2017-06-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | I did this a long time ago with a janky python script, but now clang-format has built-in support for this. I fed clang-format every line with a #include and let it re-sort things according to the precise LLVM rules for include ordering baked into clang-format these days. I've reverted a number of files where the results of sorting includes isn't healthy. Either places where we have legacy code relying on particular include ordering (where possible, I'll fix these separately) or where we have particular formatting around #include lines that I didn't want to disturb in this patch. This patch is *entirely* mechanical. If you get merge conflicts or anything, just ignore the changes in this patch and run clang-format over your #include lines in the files. Sorry for any noise here, but it is important to keep these things stable. I was seeing an increasing number of patches with irrelevant re-ordering of #include lines because clang-format was used. This patch at least isolates that churn, makes it easy to skip when resolving conflicts, and gets us to a clean baseline (again). llvm-svn: 304787
* [APInt] Move isMask and isShiftedMask out of APIntOps and into the APInt ↵Craig Topper2017-04-031-2/+2
| | | | | | | | | | class. Implement them without memory allocation for multiword This moves the isMask and isShiftedMask functions to be class methods. They now use the MathExtras.h function for single word size and leading/trailing zeros/ones or countPopulation for the multiword size. The previous implementation made multiple temorary memory allocations to do the bitwise arithmetic operations to match the MathExtras.h implementation.

* GraphTraits: Add range versions of graph traits functions (graph_nodes, ↵Daniel Berlin2017-02-091-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | graph_children, inverse_graph_nodes, inverse_graph_children). Summary: Convert all obvious node_begin/node_end and child_begin/child_end pairs to range based for. Sending for review in case someone has a good idea how to make graph_children able to be inferred. It looks like it would require changing GraphTraits to be two argument or something. I presume inference does not happen because it would have to check every GraphTraits in the world to see if the noderef types matched. Note: This change was 3-staged with clang as well, which uses Dominators/etc from LLVM.

* CodeGen: Remove MachineFunctionAnalysis => Enable (Machine)ModulePassesMatthias Braun2016-08-241-2/+0
| | | | | | | | | | | | | | | | | | | | | | Re-apply this patch, hopefully I will get away without any warnings in the constructor now. This patch removes the MachineFunctionAnalysis. Instead we keep a map from IR Function to MachineFunction in the MachineModuleInfo. This allows the insertion of ModulePasses into the codegen pipeline without breaking it because the MachineFunctionAnalysis gets dropped before a module pass. Peak memory should stay unchanged without a ModulePass in the codegen pipeline: Previously the MachineFunction was freed at the end of a codegen function pipeline because the MachineFunctionAnalysis was dropped; With this patch the MachineFunction is freed after the AsmPrinter has finished.

| | | | | | | | | | | | | | | | | | | | | | | Re-apply this commit with the deletion of a MachineFunction delegated to a separate pass to avoid use after free when doing this directly in AsmPrinter.

* Hexagon: Remove implicit ilist iterator conversions, NFCDuncan P. N. Exon Smith2015-10-201-1/+1
| | | | | | | | | | | | | | | | | | | There are two things out of the ordinary in this commit. First, I made a loop obviously "infinite" in HexagonInstrInfo.cpp. After checking if an instruction was at the beginning of a basic block (in which case, `break`), the loop decremented and checked the iterator for `nullptr` as the loop condition. This has never been possible (the prev pointers are always been circular, so even with the weird ilist/iplist implementation, this isn't been possible), so I removed the condition. Second, in HexagonAsmPrinter.cpp there was another case of comparing a `MachineBasicBlock::instr_iterator` against `MachineBasicBlock::end()` (which returns `MachineBasicBlock::iterator`). While not incorrect, it's fragile. I switched this to `::instr_end()`. All that said, no functionality change intended here. llvm-svn: 250778
