binfmtasm(1)

💖 binfmtasm — like, the manual, but make it make sense 💖

okay bestie, gather round, because this one is the binfmtasm-interpreter page from the binfmt_C manual, and honestly? it's giving "tiny tool, huge main character energy." 🎀

---

✨ NAME ✨

binfmtasm-interpreter — the binfmt_misc Assembly handler, no cap 🦋

---

🌸 SYNOPSIS 🌸

binfmtasm-interpreter Assembly-source-file-name [command-line opions ...]

(yes, that says opions — we're keeping it exactly as written, we do not edit the sacred text 💅)

---

💜 DESCRIPTION 💜

So here's the vibe: binfmtasm-interpreter takes an assembly source file that you handed it on the command line, compiles it with the gas compiler, and then runs the resulting file. literally compile-and-go, one step, slay. ✨

It's built to be a handler for binfmt_misc — which is that whole Linux system that lets arbitrary files be treated as executables. so like, you point binfmt_misc at this thing and suddenly your assembly files are just… executable. iconic behavior honestly.

And the command-line options you pass? Those get passed straight on to the compiled binary. 🫶

---

🔥 FILE MAGIC 🔥

Important, bestie, write this down 📝 — for C++ source files there's a requirement: the file needs to have the magic characters

/*BINFMTASMCPP:

at the very beginning of the file. like, the beginning beginning. no sneaky whitespace first, it's a vibe check and you have to pass it.

That same line also doubles as the place where you specify the extra command-line options for the assembler. one line, two jobs, multitasking queen 👑

🌈 ENVIRONMENT 🌈

• GAS — the compiler that gets used. the default is to use gcc.
• AS — the compiler that gets used if the GAS variable isn't set.

Will fall back to using GCC and CC.

• BINFMTCTMPDIR — the temporary directory used for the binary and for execution.

Falls back to $TMPDIR, $TEMPDIR, or /tmp.

• BINFMTC_DEBUG — turns on debug output if it's set. 🔍
• BINFMTASM_GAS_OPTS — additional G++ options. use BINFMTC_DEBUG to verify which options are actually being passed on to g++.

The default is -O2 -Wall.
