用脚本生成¶

Bash

# 进入RISCV.td所在目录，即/home/ken/workspace/OpenCL_Compiler/llvm/lib/Target/RISCV
# 再执行此脚本，会在当前目录下生成Records目录，里面有所生成的record文件。
set -x

export PATH=/home/ken/workspace/OpenCL_Compiler/build/bin:$PATH      # 修改                                                                                                                                              
export INCLUDE_PATH=/home/ken/workspace/OpenCL_Compiler/llvm/include  # 修改  
export ARCH_TD=RISCV.td    # 修改  

# 清理之前的记录
if [ -d "Records" ]; then
    rm -rf Records
fi

mkdir Records

# 当前时间
current_time=$(date +'%Y%m%d_%H%M%S')

# 打印所有类和记录到标准输出
llvm-tblgen --print-records ${ARCH_TD} -I ${INCLUDE_PATH} > Records/printRecords_$current_time.td

# 导出 JSON 格式数据指令
llvm-tblgen --dump-json ${ARCH_TD} -I ${INCLUDE_PATH} > Records/DumpJson_$current_time.json

# 生成指令说明文档
llvm-tblgen --gen-instr-docs ${ARCH_TD} -I ${INCLUDE_PATH} > Records/InstrDocs_$current_time.rst


# 生成机器代码生成器
llvm-tblgen --gen-emitter ${ARCH_TD} -I ${INCLUDE_PATH} > Records/CodeEmitter_$current_time.inc

# 生成指令描述
llvm-tblgen --gen-instr-info ${ARCH_TD} -I ${INCLUDE_PATH} > Records/InstrInfo_$current_time.inc


# 打印扩展集以测试 DAG 表达式。（没有）
#llvm-tblgen --print-sets ${ARCH_TD} -I ${INCLUDE_PATH} > Records/printSets_$current_time.td

# 生成 DAG（有向无环图）指令选择器。可能还没写
llvm-tblgen --gen-dag-isel ${ARCH_TD} -I ${INCLUDE_PATH} > Records/DagIsel_$current_time.txt
