Question 1

How to install vas without using Docker?

Accepted Answer

You need to have the V compiler installed, then build from source using 'v . -prod' as per the README. This requires manual setup and may not be as straightforward as Docker for all users.

Question 2

vas vs NASM: which is better for x86-64 assembly?

Accepted Answer

vas is minimal and V-based, ideal for learning or V ecosystem projects, while NASM offers more features like macros and wider platform support. Choose vas for simplicity, NASM for robustness.

Question 3

Can vas handle macros in assembly code?

Accepted Answer

Based on the minimal philosophy and lack of mention in the README, vas likely does not support macros or advanced preprocessing, sticking to basic assembly translation without such features.

Question 4

How to link vas output with C code?

Accepted Answer

After assembling with vas to produce an ELF .o file, use a standard linker like 'ld' or 'gcc' to combine it with C objects, similar to the example but with additional C source files.

Question 5

What platforms does vas run on aside from x86-64?

Accepted Answer

vas is an assembler for x86-64 code, but it can run on any system with V or Docker support; however, it only outputs x86-64 ELF files, limiting cross-architecture use.

Question 6

Is vas suitable for embedded systems programming?

Accepted Answer

Not typically, as it targets x86-64 ELF and lacks features for embedded constraints like memory optimization or specific microcontroller architectures, making tools like GNU AS more appropriate.

Question 7

How to debug assembly code assembled with vas?

Accepted Answer

You would rely on external debuggers like GDB, as vas does not include built-in debugging tools; ensure symbols are kept with '--keep-locals' for better traceability.
