[SystemZ] Reimplent SchedModel IssueWidth and WriteRes/ReadAdvance mappings. As a consequence of recent discussions (http://lists.llvm.org/pipermail/llvm-dev/2018-May/123164.html), this patch changes the SystemZ SchedModels so that the IssueWidth is 6, which is the decoder capacity, and NumMicroOps become the number of decoder slots needed per instruction. In addition, the SchedWrite latencies now match the MachineInstructions def-operand indexes, and ReadAdvances have been added on instructions with one register operand and one memory operand.

[SystemZ] Rework processor feature definitions and add -mcpu=archX support This patch implements two changes: - Move processor feature definition into a new file SystemZFeatures.td, and provide explicit lists of supported and unsupported features for each level of the z/Architecture. This allows specifying unsupported features in the scheduler definition files for each processor. - Add optional aliases for the -mcpu processor names according to the level of the z/Architecture, for compatibility with other compilers on the platform. The supported aliases are: -mcpu=arch8 equals -mcpu=z10 -mcpu=arch9 equals -mcpu=z196 -mcpu=arch10 equals -mcpu=zEC12 -mcpu=arch11 equals -mcpu=z13 llvm-svn: 285577

[SystemZ] Improve use of conditional instructions This patch moves formation of LOC-type instructions from (late) IfConversion to the early if-conversion pass, and in some cases additionally creates them directly from select instructions during DAG instruction selection. To make early if-conversion work, the patch implements the canInsertSelect / insertSelect callbacks. It also implements the commuteInstructionImpl and FoldImmediate callbacks to enable generation of the full range of LOC instructions. Finally, the patch adds support for all instructions of the load-store-on-condition-2 facility, which allows using LOC instructions also for high registers. Due to the use of the GRX32 register class to enable high registers, we now also have to handle the cases where there are still no single hardware instructions (conditional move from a low register to a high register or vice versa). These are converted back to a branch sequence after register allocation. Since the expandRAPseudos callback is not allowed to create new basic blocks, this requires a simple new pass, modelled after the ARM/AArch64 ExpandPseudos pass. Overall, this patch causes significantly more LOC-type instructions to be used, and results in a measurable performance improvement. llvm-svn: 288028

[SystemZ] Add remaining branch instructions This patch adds assembler support for the remaining branch instructions: the non-relative branch on count variants, and all variants of branch on index. The only one of those that can be readily exploited for code generation is BRCTH (branch on count using a high 32-bit register as count). Do use it, however, it is necessary to also introduce a hew CHIMux pseudo to allow comparisons of a 32-bit value agains a short immediate to go into a high register as well (implemented via CHI/CIH). This causes a bit of codegen changes overall, but those have proven to be neutral (or even beneficial) in performance measurements. llvm-svn: 288029

[SystemZ] Reimplent SchedModel IssueWidth and WriteRes/ReadAdvance mappings. As a consequence of recent discussions (http://lists.llvm.org/pipermail/llvm-dev/2018-May/123164.html), this patch changes the SystemZ SchedModels so that the IssueWidth is 6, which is the decoder capacity, and NumMicroOps become the number of decoder slots needed per instruction. In addition, the SchedWrite latencies now match the MachineInstructions def-operand indexes, and ReadAdvances have been added on instructions with one register operand and one memory operand.

[SystemZ] Refactor branch and conditional instruction patterns Rework patterns for branches, call & return instructions, compare-and-branch, compare-and-trap, and conditional move instructions. In particular, simplify creation of patterns for the extended opcodes of instructions that take a CC mask. Also, use semantical instruction classes for all the instructions instead of open-coding them in SystemZInstrInfo.td. Adds a couple of the basic branch instructions (that are unused for codegen) for the assembler/disassembler. llvm-svn: 286263

[SystemZ] Reimplent SchedModel IssueWidth and WriteRes/ReadAdvance mappings. As a consequence of recent discussions (http://lists.llvm.org/pipermail/llvm-dev/2018-May/123164.html), this patch changes the SystemZ SchedModels so that the IssueWidth is 6, which is the decoder capacity, and NumMicroOps become the number of decoder slots needed per instruction. In addition, the SchedWrite latencies now match the MachineInstructions def-operand indexes, and ReadAdvances have been added on instructions with one register operand and one memory operand.

[SystemZ] Reimplent SchedModel IssueWidth and WriteRes/ReadAdvance mappings. As a consequence of recent discussions (http://lists.llvm.org/pipermail/llvm-dev/2018-May/123164.html), this patch changes the SystemZ SchedModels so that the IssueWidth is 6, which is the decoder capacity, and NumMicroOps become the number of decoder slots needed per instruction. In addition, the SchedWrite latencies now match the MachineInstructions def-operand indexes, and ReadAdvances have been added on instructions with one register operand and one memory operand.

[SystemZ] Reimplent SchedModel IssueWidth and WriteRes/ReadAdvance mappings. As a consequence of recent discussions (http://lists.llvm.org/pipermail/llvm-dev/2018-May/123164.html), this patch changes the SystemZ SchedModels so that the IssueWidth is 6, which is the decoder capacity, and NumMicroOps become the number of decoder slots needed per instruction. In addition, the SchedWrite latencies now match the MachineInstructions def-operand indexes, and ReadAdvances have been added on instructions with one register operand and one memory operand.

As a consequence of recent discussions (http://lists.llvm.org/pipermail/llvm-dev/2018-May/123164.html), this patch changes the SystemZ SchedModels so that the IssueWidth is 6, which is the decoder capacity, and NumMicroOps become the number of decoder slots needed per instruction. In addition, the SchedWrite latencies now match the MachineInstructions def-operand indexes, and ReadAdvances have been added on instructions with one register operand and one memory operand.

[SystemZ] Reimplent SchedModel IssueWidth and WriteRes/ReadAdvance mappings. As a consequence of recent discussions (http://lists.llvm.org/pipermail/llvm-dev/2018-May/123164.html), this patch changes the SystemZ SchedModels so that the IssueWidth is 6, which is the decoder capacity, and NumMicroOps become the number of decoder slots needed per instruction. In addition, the SchedWrite latencies now match the MachineInstructions def-operand indexes, and ReadAdvances have been added on instructions with one register operand and one memory operand.

As a consequence of recent discussions (http://lists.llvm.org/pipermail/llvm-dev/2018-May/123164.html), this patch changes the SystemZ SchedModels so that the IssueWidth is 6, which is the decoder capacity, and NumMicroOps become the number of decoder slots needed per instruction. In addition, the SchedWrite latencies now match the MachineInstructions def-operand indexes, and ReadAdvances have been added on instructions with one register operand and one memory operand.

[SystemZ] Add all remaining instructions This adds all remaining instructions that were still missing, mostly privileged and semi-privileged system-level instructions. These are provided for use with the assembler and disassembler only. This brings the LLVM assembler / disassembler to parity with the GNU binutils tools. llvm-svn: 306876

[SystemZ] Reimplent SchedModel IssueWidth and WriteRes/ReadAdvance mappings. As a consequence of recent discussions (http://lists.llvm.org/pipermail/llvm-dev/2018-May/123164.html), this patch changes the SystemZ SchedModels so that the IssueWidth is 6, which is the decoder capacity, and NumMicroOps become the number of decoder slots needed per instruction. In addition, the SchedWrite latencies now match the MachineInstructions def-operand indexes, and ReadAdvances have been added on instructions with one register operand and one memory operand.

[SystemZ] Post-RA scheduler implementation Post-RA sched strategy and scheduling instruction annotations for z196, zEC12 and z13. This scheduler optimizes decoder grouping and balances processor resources (including side steering the FPd unit instructions). The SystemZHazardRecognizer keeps track of the scheduling state, which can be dumped with -debug-only=misched. Reviers: Ulrich Weigand, Andrew Trick. https://reviews.llvm.org/D17260 llvm-svn: 284704
