OBJ2ASM(1)

📦 version 2.109.1, in opensuse-leap 16.0

🎀 NAME 🎀

okay so bestie, welcome to OBJ2ASM(1) — the Digital Mars D manual page for obj2asm, aka the Digital Mars .OBJ file disassembler. 💅 It disassembles object files, and honestly? iconic behavior.

✨ SYNOPSIS ✨

obj2asm [-l] [-o] [-x] objfile [srcfile] [-c[outfile[.cod]]]

periodt. that's the whole shape of it. 🫶

🌸 DESCRIPTION 🌸

obj2asm disassembles object (.o) files in Intel OMF, Microsoft COFF format, or linux ELF format. object file in, assembly language file out — no cap. 🦋

💖 OPTIONS 💖

  • -l — Omit code labels in the assembly language file it generates. no labels, no problem. ✨
  • -o — Emit object code for each assembly language instruction. it's giving receipts for every instruction. 🔥
  • -x — Emit code segment offset for each instruction. offset reveal moment. 👑
  • objfile — The object to disassemble. this is the main-character file. 💅
  • srcfile — Use this if the source file name embedded in the object file is missing or incorrect. like when the object's internal source name is doing too much and lowkey lying. 🙈
  • -c[outfile[.cod]] — Writes output to outfile instead of the standard output. The default extension for outfile is .cod. yes, that exact bracket situation is the flex. 🎀

🔥 EXAMPLE 🔥

To see the code generated by compiling test.cpp, use the following commands:

dmd -c -g test
obj2asm test.o

slay. go off. 🌈

💀 BUGS 💀

Although the output of obj2asm is in MASM format, it usually requires a little editing before MASM will accept it. so yes, the output is giving MASM, but MASM might still side-eye it. 😭
