disassembly

I am studying Compilers course, compilation of program follows below steps Lexical analysis Syntax analysis Semantic analysis Intermediate code generation Code optimization Target code generation. How can I see output of each step e.g I want to see parse tree after syntax analysis. I am compiling program on Linux machine with GCC compiler. We can see assembly code of the program by using -Wa compiler option in gcc, similarly is there options to see Tokens, Parse tree and Inetmediate code. While you can use the -fdump-tree-all and -fdump-rtl-all options in gcc, I don't think that their output

I'm interested in writing an x86 dissembler as an educational project. The only real resource I have found is Spiral Space's, " How to write a disassembler ". While this gives a nice high level description of the various components of a disassembler, I'm interested in some more detailed resources. I've also taken a quick look at NASM's source code but this is somewhat of a heavyweight to learn from. I realize one of the major challenges of this project is the rather large x86 instruction set I'm going to have to handle. I'm also interested in basic structure, basic disassembler links, etc. Can

How can I see the assembly code for a C++ program? What are the popular tools to do this? Employed Russian Ask the compiler If you are building the program yourself, you can ask your compiler to emit assembly source. For most UNIX compilers use the -S switch. If you are using the GNU assembler, compiling with -g -Wa,-alh will give intermixed source and assembly on stdout ( -Wa asks compiler driver to pass options to assembler, -al turns on assembly listing, and -ah adds "high-level source" listing): g++ -g -c -Wa,-alh foo.cc For Visual Studio, use /FAsc . Peek into the binary If you have

So I was googling for a long time and i found almost nothing. I found some info about possible implementation of Math.Pow from this url , but they are inaccurate, for example this code public static double PowerA(double a, double b) { int tmp = (int)(BitConverter.DoubleToInt64Bits(a) >> 32); int tmp2 = (int)(b * (tmp - 1072632447) + 1072632447); return BitConverter.Int64BitsToDouble(((long)tmp2) << 32); } static void Main(string[] args) { double x = 12.53, y = 16.45; Console.WriteLine(Math.Pow(x, y)); Console.WriteLine(PowerA(x, y)); } provides output: 1,15158266266297E+18 8,9966384455562E+17
