在LLVM中,IR有三种表示,一种是可读的IR,类似于汇编代码,但其实它介于高等语言和汇编之间,这种表示就是给人看的,磁盘文件后缀为.ll;第二种是不可读的二进制IR,被称作位码(bitcode),磁盘文件后缀为.bc;第三种表示是一种内存格式,只保存在内存中,所以谈不上文件格式和文件后缀,这种格式是LLVM之所以编译快的一个...
代码生成器 code generator是LLVM中最复杂的一个部分,任务是将相对high-level,不依赖目标机器的LLVM IR转化为 low-level的,依赖目标的机器指令(Machine Instr)。在生成Machine Instr之前,LLVM IR的指令会经过“Selection DAG node”转化。 Selection DAG Node Selection DAG Node是由Selection DAG Builder在Selection DA...

Back-end: compiles IR to machine code. Getting the Source Code and Building LLVM The LLVM Getting Started documentation may be out of date. The Clang Getting Started page might have more accurate information. This is an example workflow and configuration to get and build the LLVM source: ...

The LLVM suitemaycompile on other platforms, but it is not guaranteed to do so. If compilation is successful, the LLVM utilities should be able to assemble, disassemble, analyze, and optimize LLVM bitcode. Code generation should work as well, although the generated native code may not work ...
I'll look into your issue when that is done. Can you provide an LLVM IR bitcode file of the failing test? That'd help pin the bug down. 👍 1 Author saudet commented Jan 8, 2021 I'm attaching what I get from compiled_lib.lib.get_source() for the BERT model above on llvm...
