* [Nios2] Remove Nios2 backendCraig Topper2019-01-1550-2941/+0
| | | | | | | | As mentioned here http://lists.llvm.org/pipermail/llvm-dev/2019-January/129121.html This backend is incomplete and has not been maintained in several months. Differential Revision: https://reviews.llvm.org/D56691 llvm-svn: 351231

* [nios2] Add missing Nios2CodeGen -> Nios2AsmPrinter linkageMichal Gorny2018-11-211-0/+1
| | | | | | | | | | | | | | | | Add missing linkage from Nios2CodeGen library to Nios2AsmPrinter library. The missing dependency causes shared-lib build to fail with the following reason: lib/Target/Nios2/CMakeFiles/LLVMNios2CodeGen.dir/Nios2AsmPrinter.cpp.o: In function `(anonymous namespace)::Nios2AsmPrinter::PrintAsmMemoryOperand(llvm::MachineInstr const*, unsigned int, unsigned int, char const*, llvm::raw_ostream&)': Nios2AsmPrinter.cpp:(.text._ZN12_GLOBAL__N_115Nios2AsmPrinter21PrintAsmMemoryOperandEPKN4llvm12MachineInstrEjjPKcRNS1_11raw_ostreamE+0x2b): undefined reference to `llvm::Nios2InstPrinter::getRegisterName(unsigned int)' lib/Target/Nios2/CMakeFiles/LLVMNios2CodeGen.dir/Nios2AsmPrinter.cpp.o: In function `(anonymous namespace)::Nios2AsmPrinter::PrintAsmOperand(llvm::MachineInstr const*, unsigned int, unsigned int, char const*, llvm::raw_ostream&)': Nios2AsmPrinter.cpp:(.text._ZN12_GLOBAL__N_115Nios2AsmPrinter15PrintAsmOperandEPKN4llvm12MachineInstrEjjPKcRNS1_11raw_ostreamE+0x97): undefined reference to `llvm::Nios2InstPrinter::getRegisterName(unsigned int)' collect2: error: ld returned 1 exit status Differential Revision: https://reviews.llvm.org/D47810 llvm-svn: 347387

* Rename DEBUG macro to LLVM_DEBUG.Nicola Zaghen2018-05-141-1/+1
| | | | | | | | | | | | | | | | The DEBUG() macro is very generic so it might clash with other projects. The renaming was done as follows: - git grep -l 'DEBUG' | xargs sed -i 's/\bDEBUG\s\?(/LLVM_DEBUG(/g' - git diff -U0 master | ../clang/tools/clang-format/clang-format-diff.py -i -p1 -style LLVM - Manual change to APInt - Manually chage DOCS as regex doesn't match it. In the transition period the DEBUG() macro is still present and aliased to the LLVM_DEBUG() one. Differential Revision: https://reviews.llvm.org/D43624 llvm-svn: 332240
* Sort targetgen calls in lib/Target/*/CMakeLists.Nico Weber2018-04-041-7/+2
| | | | | | | | | | | Makes it easier to see mistakes such as the one fixed in r329178 and makes the different target CMakeLists more consistent. Also remove some stale-looking comments from the Nios2 target cmakefile. No intended behavior change. llvm-svn: 329181
* [SelectionDAGISel] Add a debug print before call to Select. Adjust where ↵Craig Topper2018-01-261-3/+0
| | | | | | | | | | | | blank lines are printed during isel process to make things more sensibly grouped. Previously some targets printed their own message at the start of Select to indicate what they were selecting. For the targets that didn't, it means there was no print of the root node before any custom handling in the target executed. So if the target did something custom and never called SelectNodeCommon, no print would be made. For the targets that did print a message in Select, if they didn't custom handle a node SelectNodeCommon would reprint the root node before walking the isel table. It seems better to just print the message before the call to Select so all targets behave the same. And then remove the root node printing from SelectNodeCommon and just leave a message that says we're starting the table search. There were also some oddities in blank line behavior. Usually due to a \n after a call to SelectionDAGNode::dump which already inserted a new line. llvm-svn: 323551
* [Nios2] Arithmetic instructions for R1 and R2 ISA.Nikolai Bozhenov2018-01-095-11/+138
| | | | | | | | | | | | | | Summary: This commit enables some of the arithmetic instructions for Nios2 ISA (for both R1 and R2 revisions), implements facilities required to emit those instructions and provides LIT tests for added instructions.

* [Nios2] final infrastructure to provide compilation of a return from a functionNikolai Bozhenov2017-12-0745-109/+1857
| | | | | | | | | | | | This patch includes all missing functionality needed to provide first compilation of a simple program that just returns from a function. I've added a test case that checks for "ret" instruction printed in assembly output.

* Fix a bunch more layering of CodeGen headers that are in TargetDavid Blaikie2017-11-172-2/+2
| | | | | | | | All these headers already depend on CodeGen headers so moving them into CodeGen fixes the layering (since CodeGen depends on Target, not the other way around). llvm-svn: 318490
* Target/TargetInstrInfo.h -> CodeGen/TargetInstrInfo.h to match layeringDavid Blaikie2017-11-081-1/+1
| | | | | | | | This header includes CodeGen headers, and is not, itself, included by any Target headers, so move it into CodeGen to match the layering of its implementation. llvm-svn: 317647
* Move TargetFrameLowering.h to CodeGen where it's implementedDavid Blaikie2017-11-031-1/+1
| | | | | | | | | | | This header already includes a CodeGen header and is implemented in lib/CodeGen, so move the header there to match. This fixes a link error with modular codegeneration builds - where a header and its implementation are circularly dependent and so need to be in the same library, not split between two like this. llvm-svn: 317379
* Revert "TargetMachine: Merge TargetMachine and LLVMTargetMachine"Matthias Braun2017-10-122-3/+3
| | | | | | | | | | Reverting to investigate layering effects of MCJIT not linking libCodeGen but using TargetMachine::getNameWithPrefix() breaking the lldb bots. This reverts commit r315633. llvm-svn: 315637
* TargetMachine: Merge TargetMachine and LLVMTargetMachineMatthias Braun2017-10-122-3/+3
| | | | | | | | | | | | | | | Merge LLVMTargetMachine into TargetMachine. - There is no in-tree target anymore that just implements TargetMachine but not LLVMTargetMachine. - It should still be possible to stub out all the various functions in case a target does not want to use lib/CodeGen - This simplifies the code and avoids methods ending up in the wrong interface.

* [Nios2] Subtarget, basic infrastructure for frame, instructions and registersNikolai Bozhenov2017-09-1915-20/+545
| | | | | | | | | | | | | | This is the second minimal patch keeping Nios2 target buildable. I'm adding subtarget here and other stuff for frame lowering, instruction, register information methods. I do not add any test cases, as still there are missing parts like DAG selector and assembly printing. I plan to include them into the next patch.
