Valgrind helper

The Valgrind plugin Callgrind can be used to profile D code, but it does not know how to handle D's mangled names. This program can be used to clean up the callgrind.out.nnnnn file so that tools like KCachegrind can display them more legibly.

Code

dcallgrind.d

import std.stdio;
import std.demangle;
import std.regex;
import std.conv;

auto re = ctRegex!(`(_D\d[\w_]+)`);

void main(string[] args)
{
    auto isStdin = args.length == 1;
    auto inFile = isStdin ? stdin : File(args[1]);
    auto outFile = isStdin ? stdout : File(args[1] ~ ".demangled", "w");
    foreach (l; inFile.byLine(KeepTerminator.yes))
        outFile.write(replace!(a => demangle(to!string(a.hit)))(l, re));
}

Usage

./dcallgrind callgrind.out.27497

This will create a file called callgrind.out.27497.demangled that you can then view using KCachegrind.


Interactive D Compiler

If you want to see the assembly your D code compiles to, please use the following Interactive D compiler.

MiniLibD - Embedded D usage

This collection has libraries and tools to compile D language programs for embedded systems with the gdc compiler.

The original D runtime library uses libraries from the operating system. It can not be used in embedded systems when there is no operating system.
