Zi Xuan Wu	ec17c4f075	[CSKY 3/n] Add bare-bones C-SKY MCTargetDesc ... Add basis of CSKY MCTargetDesc and it's enough to compile and link but doesn't yet do anything particularly useful. Once an ASM parser and printer are added in the next two patches, the whole thing can be usefully tested. Differential Revision: https://reviews.llvm.org/D93372	2020-12-22 11:32:39 +08:00
Zi Xuan Wu	365c405411	[CSKY 2/n] Add basic tablegen infra for CSKY ... This introduce basic tablegen infra such as CSKY{InstrFormats,InstrInfo,RegisterInfo,}.td. For now, only add instruction definitions for basic CSKY ISA operations, and the instruction format and register info are almost complete. Our initial target is a working MC layer rather than codegen, so appropriate SelectionDAG patterns will come later. Differential Revision: https://reviews.llvm.org/D89180	2020-12-07 11:56:09 +08:00
serge-sans-paille	9218ff50f9	llvmbuildectomy - replace llvm-build by plain cmake ... No longer rely on an external tool to build the llvm component layout. Instead, leverage the existing `add_llvm_componentlibrary` cmake function and introduce `add_llvm_component_group` to accurately describe component behavior. These function store extra properties in the created targets. These properties are processed once all components are defined to resolve library dependencies and produce the header expected by llvm-config.

Zi Xuan Wu	e1c38dd55d	[CSKY 1/n] Add basic stub or infra of csky backend ... This patch introduce files that just enough for lib/Target/CSKY to compile. Notably a basic CSKYTargetMachine and CSKYTargetInfo. Differential Revision: https://reviews.llvm.org/D88466	2020-10-10 10:44:08 +08:00
