[RISCV] Support and tests for a variety of additional LLVM IR constructs Previous patches primarily ensured that codegen was possible for the standard RISC-V instructions. However, there are a number of IR inputs that wouldn't be appropriately lowered. This patch both adds test cases and supports lowering for a number of these cases: * Improved sext/zext/trunc support * Support for setcc variants that don't map directly to RISC-V instructions * Lowering mul, and hence support for external symbols * addc, adde, subc, sube * mulhs, srem, mulhu, urem, udiv, sdiv * {srl,sra,shl}_parts * brind * br_jt * bswap, ctlz, cttz, ctpop * rotl, rotr * BlockAddress operands Differential Revision: https://reviews.llvm.org/D29938 llvm-svn: 318737

[RISCV] Introduce codegen patterns for instructions introduced in RV64I As discussed in the RFC <http://lists.llvm.org/pipermail/llvm-dev/2018-October/126690.html>, 64-bit RISC-V has i64 as the only legal integer type. This patch introduces patterns to support codegen of the new instructions introduced in RV64I: addiw, addiw, subw, sllw, slliw, srlw, srliw, sraw, sraiw, ld, sd. Custom selection code is needed for srliw as SimplifyDemandedBits will remove lower bits from the mask, meaning the obvious pattern won't work: def : Pat<(sext_inreg (srl (and GPR:$rs1, 0xffffffff), uimm5:$shamt), i32), (SRLIW GPR:$rs1, uimm5:$shamt)>; This is sufficient to compile and execute all of the GCC torture suite for RV64I other than those files using frameaddr or returnaddr intrinsics (LegalizeDAG doesn't know how to promote the operands - a future patch addresses this). When promoting i32 sltu/sltiu operands, it would be more efficient to use sign-extension rather than zero-extension for RV64. A future patch adds a hook to allow this.

[RISCV] Introduce codegen patterns for instructions introduced in RV64I As discussed in the RFC <http://lists.llvm.org/pipermail/llvm-dev/2018-October/126690.html>, 64-bit RISC-V has i64 as the only legal integer type. This patch introduces patterns to support codegen of the new instructions introduced in RV64I: addiw, addiw, subw, sllw, slliw, srlw, srliw, sraw, sraiw, ld, sd. Custom selection code is needed for srliw as SimplifyDemandedBits will remove lower bits from the mask, meaning the obvious pattern won't work: def : Pat<(sext_inreg (srl (and GPR:$rs1, 0xffffffff), uimm5:$shamt), i32), (SRLIW GPR:$rs1, uimm5:$shamt)>; This is sufficient to compile and execute all of the GCC torture suite for RV64I other than those files using frameaddr or returnaddr intrinsics (LegalizeDAG doesn't know how to promote the operands - a future patch addresses this). When promoting i32 sltu/sltiu operands, it would be more efficient to use sign-extension rather than zero-extension for RV64. A future patch adds a hook to allow this.

[RISCV] Introduce codegen patterns for instructions introduced in RV64I As discussed in the RFC <http://lists.llvm.org/pipermail/llvm-dev/2018-October/126690.html>, 64-bit RISC-V has i64 as the only legal integer type. This patch introduces patterns to support codegen of the new instructions introduced in RV64I: addiw, addiw, subw, sllw, slliw, srlw, srliw, sraw, sraiw, ld, sd. Custom selection code is needed for srliw as SimplifyDemandedBits will remove lower bits from the mask, meaning the obvious pattern won't work: def : Pat<(sext_inreg (srl (and GPR:$rs1, 0xffffffff), uimm5:$shamt), i32), (SRLIW GPR:$rs1, uimm5:$shamt)>; This is sufficient to compile and execute all of the GCC torture suite for RV64I other than those files using frameaddr or returnaddr intrinsics (LegalizeDAG doesn't know how to promote the operands - a future patch addresses this). When promoting i32 sltu/sltiu operands, it would be more efficient to use sign-extension rather than zero-extension for RV64. A future patch adds a hook to allow this.

[RISCV] Introduce codegen patterns for instructions introduced in RV64I As discussed in the RFC <http://lists.llvm.org/pipermail/llvm-dev/2018-October/126690.html>, 64-bit RISC-V has i64 as the only legal integer type. This patch introduces patterns to support codegen of the new instructions introduced in RV64I: addiw, addiw, subw, sllw, slliw, srlw, srliw, sraw, sraiw, ld, sd. Custom selection code is needed for srliw as SimplifyDemandedBits will remove lower bits from the mask, meaning the obvious pattern won't work: def : Pat<(sext_inreg (srl (and GPR:$rs1, 0xffffffff), uimm5:$shamt), i32), (SRLIW GPR:$rs1, uimm5:$shamt)>; This is sufficient to compile and execute all of the GCC torture suite for RV64I other than those files using frameaddr or returnaddr intrinsics (LegalizeDAG doesn't know how to promote the operands - a future patch addresses this). When promoting i32 sltu/sltiu operands, it would be more efficient to use sign-extension rather than zero-extension for RV64. A future patch adds a hook to allow this.

[RISCV] Introduce codegen patterns for instructions introduced in RV64I As discussed in the RFC <http://lists.llvm.org/pipermail/llvm-dev/2018-October/126690.html>, 64-bit RISC-V has i64 as the only legal integer type. This patch introduces patterns to support codegen of the new instructions introduced in RV64I: addiw, addiw, subw, sllw, slliw, srlw, srliw, sraw, sraiw, ld, sd. Custom selection code is needed for srliw as SimplifyDemandedBits will remove lower bits from the mask, meaning the obvious pattern won't work: def : Pat<(sext_inreg (srl (and GPR:$rs1, 0xffffffff), uimm5:$shamt), i32), (SRLIW GPR:$rs1, uimm5:$shamt)>; This is sufficient to compile and execute all of the GCC torture suite for RV64I other than those files using frameaddr or returnaddr intrinsics (LegalizeDAG doesn't know how to promote the operands - a future patch addresses this). When promoting i32 sltu/sltiu operands, it would be more efficient to use sign-extension rather than zero-extension for RV64. A future patch adds a hook to allow this.

[RISCV] Introduce codegen patterns for instructions introduced in RV64I As discussed in the RFC <http://lists.llvm.org/pipermail/llvm-dev/2018-October/126690.html>, 64-bit RISC-V has i64 as the only legal integer type. This patch introduces patterns to support codegen of the new instructions introduced in RV64I: addiw, addiw, subw, sllw, slliw, srlw, srliw, sraw, sraiw, ld, sd. Custom selection code is needed for srliw as SimplifyDemandedBits will remove lower bits from the mask, meaning the obvious pattern won't work: def : Pat<(sext_inreg (srl (and GPR:$rs1, 0xffffffff), uimm5:$shamt), i32), (SRLIW GPR:$rs1, uimm5:$shamt)>; This is sufficient to compile and execute all of the GCC torture suite for RV64I other than those files using frameaddr or returnaddr intrinsics (LegalizeDAG doesn't know how to promote the operands - a future patch addresses this). When promoting i32 sltu/sltiu operands, it would be more efficient to use sign-extension rather than zero-extension for RV64. A future patch adds a hook to allow this.

[RISCV] Introduce codegen patterns for instructions introduced in RV64I As discussed in the RFC <http://lists.llvm.org/pipermail/llvm-dev/2018-October/126690.html>, 64-bit RISC-V has i64 as the only legal integer type. This patch introduces patterns to support codegen of the new instructions introduced in RV64I: addiw, addiw, subw, sllw, slliw, srlw, srliw, sraw, sraiw, ld, sd. Custom selection code is needed for srliw as SimplifyDemandedBits will remove lower bits from the mask, meaning the obvious pattern won't work: def : Pat<(sext_inreg (srl (and GPR:$rs1, 0xffffffff), uimm5:$shamt), i32), (SRLIW GPR:$rs1, uimm5:$shamt)>; This is sufficient to compile and execute all of the GCC torture suite for RV64I other than those files using frameaddr or returnaddr intrinsics (LegalizeDAG doesn't know how to promote the operands - a future patch addresses this). When promoting i32 sltu/sltiu operands, it would be more efficient to use sign-extension rather than zero-extension for RV64. A future patch adds a hook to allow this.
