BRIR的GetOperands返回空数组

针对下面的输入：

int main() {
  int a = 10;
}

生成下面的LLVM IR

define i32 @main( ) {
block114514:
  br label %block114514
block114514:
  ret i32 0
}


declare i32 @getint()
declare i32 @getch()
declare float @getfloat()
declare i32 @getarray(i32* %0)
declare i32 @getfarray(float* %0)
declare void @putint(i32 %0)
declare void @putch(i32 %0)
declare void @putarray(i32 %0, i32* %1)
declare void @putfloat(float %0)
declare void @putfarray(i32 %0, float* %1)
declare void @putf(i8* %0, ...)
declare void @before_main()
declare void @after_main()
declare void @_sysy_starttime(i32 %0)
declare void @_sysy_stoptime(i32 %0)


declare void @llvm.memset.p0.i32(ptr nocapture writeonly, i8, i32, i1 immarg)

问题一：LLVM IR中的两个block的编号相同呢 问题二：BRIR的GetOperands返回空数组，导致后端运行出错
