Also, if youNot gcc, but when debugging in Visual Studio you have the option to intersperse assembly and source.
The generated assembly so you can more easily see what the compiler did to optimize your code.

I have a compiler that targets the .NET runtime (CLR). The current version of the compiler is written in standard C++ (non-managed). The compiler currently lacks support to reference assemblies at compile time, so the way I "import" .NET libraries is ...

Ask for IID_IMetaDataAssemblyImport, it has a bunch of methods.
HRESULT hrStart = pClrHost->Start(); // Load an assembly and execute() lets you open the assembly metadata.
); // Now, start the CLR.

I want to use the bts and bt x86 assembly instructions to speed up bit operations in my C++ code on the Mac. On Windows, the _bittestandset and _bittest intrinsics work well, and provide significant performance gains. On the Mac, the gcc compiler doesn...

Another slightly indirect answer, GCC exposes a number of atomic operations starting with version 4.1 .
Not a direct answer, just a link to GCC Extended Asm documentation .

I am trying to optimize a lot of multiplications and pointer arithmetics and would like to see what the compiler does underneath when I put in optimization flags.

How to restrict it to a specific function or a code block?

Edit: Do not forget that it will place the assembly to the files you specified under -o switch.
Add -S switch to your command line.

I am encountering a strange build issue in .NET 3.5. The compiler is crashing when it attempts to build a Web Deployment Project.

Try clearing out your [Windows folder]\Microsoft .NET\Framework\2.0xxx\Temporary ASP.NET Files*.* folder - that can sometimes get gummed up with GB's of temp files .

I have assembly A with class Z that inherits from class X in assembly B. Now in a completely different solution, I have assembly C, which uses class Z.
The compiler complains unless assembly C has a reference to both assembly A & B. Even though assembly...

Compiler , the image is pretty simple and takes the primordial concept.
For example, an assembler takes assembly language code as input and produces binary object code as output.

I was wondering if there's some special way to compile high-level code (preferably from c/c++ or java) to get the corresponding assembly code.

Gcc can dump an assembly listing using -S switch - it will emit the assembly code to a file with a .s extension.
S -c foo.c
look at the manual/doco for your compiler - i m sure there is an option to do it.
