Questions tagged [intermediate-language]

An intermediate language, in compiler design, is a low-level language that typically resembles an idealized assembly language, often a textual representation of bytecode for a virtual machine. For .NET's CIL, use the [cil] tag.

An intermediate language, in compiler design, is a translation stage after the syntax tree and before the machine code. The term is usually used for final stages of the translation, after high-level optimizations have been performed, but at a stage when the translation is still independent of the target machine.

In particular, “intermediate language” often means a low-level, assembly-like language for a virtual machine such as the JVM, .NET, Prolog's WAM, etc.

For example, the .NET Common Intermediate Language is the assembly language for the virtual machine that is the target of and other compilers.

Javascript object representation format

In compiler IR representation, we know that function type can be represented using Cartesian Product. For example: function my_func(a, b) { return c; } the function type can be denoted as: (int × double)->int (note that here I assume that all…

Intermediate Code Generation for my Fortran compiler: DAG or quadruples

I'm writing a mini Fortran compiler using Flex and Bison. Up to now I've finished the lexical and syntax analysis. I'm in the semantic analysis in type checking and I must now choose an IR. My target machine is MIPS. So I want final code generation…

Does compiler optimizes unnecessary/redundant upcast away or Does it produce any IL at all?

From Do redundant casts get optimized? I can see compiler doesn't optimizes unnecessary downcast (i.e. castclass) away. But now I am interested in a simpler case, " if compiler optimizes unnecessary upcast away?" This question only concerns…

What happens if we add lines to IL code and add breakpoints to our program?

If I add let's say 1 line at the beggining of a method, if I set a breakpoint through Visual Studio on the first line, will it point to the first line or the second? If it will flag the wrong line, is there anything we could do when editing .exe…
