[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

[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] 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] 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

[SystemZ] Correct the SchedModel regarding vector unit / instructions. * Use a generic vector unit to model the issue unit more accurately. * Update some vector instructions that actually use the vector unit for more than one cycle. Review: Ulrich Weigand llvm-svn: 286112
