将std :: string转换为llvm :: MemoryBuffer [英] Convert std::string to llvm::MemoryBuffer

问题描述

我希望从现有的LLVM IR代码创建LLVM模块.

I am looking to create an LLVM Module from existing LLVM IR code.

我发现的两种方法如下:

The two methods I have found are the following:

• ParseIRFile-这将接受文件名并生成一个模块
• ParseIR-这接受MemoryBuffer并生成一个模块

• ParseIRFile - This accepts a file name and generates a module
• ParseIR - This accepts MemoryBuffer and generates a module

当LLVM IR已作为std::string或const char *读取到字符串时，我想创建一个模块.

I want to create a Module when the LLVM IR is already read to a string as an std::string or const char *.

是否可以将IR字符串转换为llvm::MemoryBuffer?

Is there a way to convert an IR string to llvm::MemoryBuffer ?

推荐答案

我在同事的帮助下解决了这个问题.

I figured this out with the help of a colleague.

这是您要执行的操作:

std::string IRString = readfile("add.ll");
MemoryBuffer *mem = MemoryBuffer::getMemBuffer(IRString);
