Ctasm -- Compile Time Assembler for C++ (WIP)

Idea

Ctasm is fully implemented in C++ templates (they are turing complete) and allows you to compile assembly code in NASM syntax from a string, saving the resulting machine code to an array without traces of the source string in the program.

Features

• extends: sse, sse2, sse4_2, avx, avx2 & etc...

Tested on

• clang >= 12.0
• gcc >= 11.1
• msvc >= 19.30

Example

    auto bytes = ctasm(R"(
        movdqu xmm0, zword ptr [rdi]
        paddd xmm0, zword ptr [rsi]
        movups zword ptr [rdi], xmm0
        ret
)");
    
  for (auto &i : bytes)
    std::cout << std::hex << (int)i << ' ';
  std::cout << '\n';
