April 08, 2012 DMD/Windows: Inspect generated ASM? | ||||
---|---|---|---|---|
| ||||
Hi all, Which is the most convenient way to have a look at the ASM code generated by Win-dmd? Unlike gdc, dmd it has no -S option, so I guess I will have to disassemble .obj files. Any good tools for this (link)? So far I only found old .obj tools from the 90s on the web... Thanks, Stefan |

I use objconv. http://www.agner.org/optimize/#objconv I use this batch script to disasm an .obj file and open the .asm file: @echo off setlocal EnableDelayedExpansion objconv -fnasm %~nx1 %~n1_disasm.asm && %~n1_disasm.asm I forgot by now just how those %~ thingies work. Windows batch is a funny language. |

I'd like that. This seems a nice enhancement request for you to add in Bugzilla.

Yup, sometimes you want to look "under the hood" of the compiler to tweak things a little. Or just to understand how a 64bit multiplication works on a IA32 machine :-)
I wonder, though, if the dmd backend has a "real" ASM stage, or if some intermediate code is directly translated into an opcode stream (like the RTL stuff in the GCC backend).
Cheers,
Stefan

That's why I love cygwin, no funny percent stuff there ;-)
Cheers,
